The Power of Big Data

The amount of power data we collect grows with each ride, each month of rides, each year of rides. A whole record of our history begins to emerge, and the result is enlightening.

Winter Hydration

In winter the cold weather tends to dull our sense of thirst, and water is less appealing in the cold. But we need just as much water after workouts in the winter as in summer!

Off Season Homework for Triathletes

While "off season" sounds so vacation-like, most of us know it's anything but. It's the crucial time to get in your homework for next year's season, especially if you're aiming for the next level of success.

How to Interpret Power Data and What to Do With It

A power meter is an incredible tool and one of the most important purchases a cyclist or triathlete can make. But it won't do you any good unless you know how to use the information it gathers.

Winter Bike Maintenance

Winter Bike Maintenance Peaks Coaching Group

We are smack dab in the middle of winter here in the USA. The roads are snowy and icy in most parts of the country, leaving many of us stuck on trainers, riding indoors. Our bikes haven't seen pavement in weeks. But all is not lost: spring is just a few months away!

During this period of winter training, it's easy to forget to maintain our equipment. But right now is actually a great time for maintenance. If you're a triathlete, your bike is most likely your most important piece of equipment. If you're a cyclist, your bike is your main piece of equipment. Take time now to run through the following list of preventive chores:

  • Clean and lubricate your drivetrain and gears.
  • Replace your brake pads.
  • Clean the rims of your wheels.
  • Check and tighten up the screws and bolts on your bike, and make sure they're all at the proper torque.
  • Check your pedals and shoes. You may want to replace your cleats or at least tighten the screws that hold your cleats to your shoes. You may also want to replace the insoles inside your shoes and any piece of your cycling shoes that's worn out.
  • Replace the batteries in your power meter and, if needed, send in your power meter to get calibrated.

A little bit of winter maintenance will make your winter training a lot easier and set you up for success in your early spring training.

If you do ride outside during these winter months, remember that the salt left on the road often causes corrosion on your bike. Don't forget to clean your bike well after these “salty” winter rides.

Stay warm and safe!

How to Get Started Training with Power

So you’ve made the commitment and purchased a power meter. Congratulations! Now it’s time to suit up for the weather and head out for your first ride.

During your first ride with your power meter, and even your first several rides, try not to look at the head unit at all. Your power meter is much more responsive to changes in input than your heart rate monitor or your speedometer, so just ride. Besides, until you know what you are looking at, the watts readout on your head unit will be almost meaningless. Power is not like speed. Your watts will fluctuate much more than you expect, and this is normal.

Take a couple days or a week to go on several rides that target different levels of perceived effort, otherwise known as rate of perceived exertion (RPE). Ride a long endurance ride. Find a hill that takes you 5-8 minutes to ride and hit it as hard as you can, or do a few hard sprints to the mailbox at the end of the road.

Then find a long stretch of uninterrupted road to do a hard 20-minute effort. This 20-minute effort is the standard effort to determine your functional threshold power (FTP).  Make sure you get a good warm-up, then crank out twenty minutes as hard as you can go. Calculate 95% of the average power for this effort: this is a reliable estimate of your FTP. Click here for a more complete description of functional threshold power and the testing process.

Hint: Make sure you hit the lap function on your head unit so you can easily find your efforts when you look at your data in an analysis software package. WKO+ and its online companion, TrainingPeaks, are two good options for analysis tools.

The next step is to determine your power zones, which will add structure and efficiency to your training. You can use the chart below to establish your zones.

Now you’ve got the basics to start riding with power. But this is only the beginning! You’ll enjoy ride analysis, targeted training data for you and your coach, event planning, and immediate feedback from your head unit. You’ll soon understand why training with a power meter is far superior to working with any other training tool.

Want to get even more out of your power meter? Request information about our coaching packages or schedule a consulting session with one of our expert coaches. With power training, we get powerful results.

Using Power-Based Metrics in an Annual Training Plan

PCG athlete Lefteris Bokas wins the Parnis Race
Since the advent of periodization over fifty years ago, coaches have sought to quantify the amount of training their athletes perform as part of developing training plans that ensure peak performance at key events. Traditionally, training load has been measured two ways—total distance and/or total hours ridden. While these measures provide some indication of training load, they lack the specificity required to assist the athlete in achieving peak fitness and minimizing the risks of over-training.

Using training zones in workouts adds some specificity to simple measures of time or distance. However, training zones indicate only the quality of the training performed and are too broad to provide an accurate indication of overall training load. For example, consider the difference in intensity between riding one hour at 60% of threshold power versus one hour at 70%. Both would fall within the endurance training zone, yet clearly the second ride is going to produce more training stimulus, possibly as much as 36% more, a significant difference when trying to plan a steady, safe progression in fitness.

Adding Power-Based Metrics

With the introduction of power meters, coaches had a new metric at their disposal: the kilojoule, a measure of the actual work performed by the athlete. The kilojoule provides a more specific measure of training volume than do total hours or distance. If we take the same two rides mentioned above but set a goal in terms of kilojoules achieved rather than time or distance, the ride at 60% would simply be extended to 70 minutes in order to equal the amount of work performed in the one-hour ride at 70%.

The use of kilojoules works very well for rides at lower levels of intensity, but because the power-work relationship is linear, it still fails to adequately represent the true training stimulus produced by harder efforts, such as intervals. The muscular fatigue and recovery requirements following an hour workout in which an athlete does six five-minute efforts at VO2Max are much higher than riding one hour steadily at 75% of threshold power, yet the two rides require the same number of kilojoules of work.

A New Method for New Data

With the development of more capable cycle computers and robust analysis software, coaches and athletes now have numerous power-based metrics at their disposal to quantify training stimulus and fitness much more accurately. It is now possible for coaches to design and implement an annual training plan that utilizes these power-based metrics instead of the more traditional miles or hours ridden. Most software programs designed to analyze power data provide the three metrics needed to design an annual plan:
  1. The relative intensity of the workout (adjusted by an algorithm to account for the higher impact of super-threshold efforts)
  2. The training stimulus for the workout (a number of points based on relative intensity and workout duration)
  3. The athlete's current level of fitness (a number of points based on the cumulative effects of several weeks of workouts)
A plan that uses power-based metrics still uses many of the core principles found in more traditional training plans. The macrocycle will be composed of several mesocycles designed first to develop the athlete's aerobic fitness and then to work on more specific energy systems in preparation for the racing peak (I’ll discuss some variations to this more traditional approach later in the article). Maintaining a familiar overall structure to the annual plan makes it easier for an athlete to adapt to a new way of thinking about training and provides the coach with a familiar methodology from which to adjust to this different approach.

After determining the athlete's current level of fitness (either through the analysis of past workout files or through an approximation of average daily training load), the coach plans the athlete's progression by entering future values for weekly training stimulus, taking into consideration recovery, planned breaks from training, and other events that may affect training. For example, if an athlete currently has 60 fitness “points” and the goal is to build that up to 100 in eight weeks, the coach plans a weekly training load that allows the athlete to reach this score of 100 at an average of 5 points per week. These weekly training load goals, in combination with a graphical representation of their impact on athlete fitness (as in the chart below), can be a useful means to help an athlete visualize the annual plan and how it will prepare them for goal events.

A graphical representation of athlete fitness can help athletes see the big picture.

Next, the coach plans each microcycle, ensuring that the workouts meet the specific training needs of the athlete and also elicit the weekly training stimulus desired based on the annual plan. Factors such as available hours to train and the athlete's daily schedule are considered during this step. As the athlete completes the microcycles, actual values for weekly training stimuli are entered, and fitness progression is adjusted up or down based on the actual training load.

Providing Data-Driven Feedback to the Athlete

In addition to the fitness progression graph shown above, creating graphs that compare actual versus planned progress can be an excellent way to present the athlete a quick picture of his weekly performance in relation to his goals and evidence of his overall fitness progression. They also motivate the athlete beyond just completing each individual workout by providing both medium and long-term feedback about the athlete's progress.

Graphs representing actual (dashed red line) vs. planned (solid blue line)
weekly stimulus (left) and overall fitness (right)

The coach makes modifications to the weekly goals as needed to suit the athlete's situation. This will occur frequently when first developing the plan, as both the coach and athlete will still be learning how much training stimulus the athlete can perform each week and how the athlete handles the overall training load across each mesocycle. With time, however, both coach and athlete will be able to tailor the workload and recovery periods to suit the athlete's needs and abilities. Since the plan is power-based, increases in the athlete's threshold power are automatically factored in to the calculations of training stimulus, as long as the coach and athlete make the appropriate changes in the program they’re using.

Special Considerations and Potential Pitfalls

Naturally, each athlete is an individual, and this approach to developing an annual plan requires attention to that fact. Since power-based metrics are derived from both intensity and duration, an athlete can derive the same number of stimulus “points” riding long duration at low intensity as they would doing intervals at aerobic capacity for a short duration, yet the physiological benefits they would receive are quite different. Therefore, the coach must ensure that the prescribed training focuses on targeting the energy systems specific to the athlete's stage of development and the demands of his goal events, not merely the achievement of some arbitrary number of training stimulus points.

In addition, special attention must be paid to the overall fitness ramp rate: the rate at which an athlete increases his fitness level each week. Depending upon the software one uses, there is typically a range of points that is considered an acceptable rate of weekly increase, beyond which the athlete runs greater risk of over-training. Additional factors such as athlete age, prior injuries, and overall resilience can affect the range of points that will be most productive. Utilizing a graphical representation of an athlete's weekly ramp rate can be a very effective means of ensuring that the athlete is able to steadily progress.

Charting the fitness “ramp rate.” The colored lines indicate the range of rates appropriate for the athlete.

As with all annual plans, unforeseen disruptions will prevent the athlete from completing both prescribed workouts within a microcycle or even entire microcycles within a mesocycle. When this occurs, traditionally the athlete either writes the missed work off entirely or attempts to make up the missed work by suddenly increasing training volume. With a power-metric training plan, the coach and athlete can collaborate to determine how much, if any, additional training load can be applied across several weeks while still keeping the athlete's ramp rate within the appropriate range. This collaboration is most productive when combined with a graphical representation of how the lost training stimulus and the resulting alterations to the upcoming weeks will get the athlete back on track, since it allows the athlete to see how short-term setbacks in training self-correct over time.

The charting of athlete fitness helps the athlete see the impact of missed training (sudden dip in dashed line)
and adapt the training plan to regain lost fitness without risking over-training.

Variations to the Plan

Using power-based metrics presents several opportunities for modification of the annual plan to suit the needs of the athlete. A few possible variations include:
  • Athletes engaged in a weight-loss phase during the post- or pre-season can include the number of kilojoules burned along with the training stimulus metrics to ensure that they consume enough calories to lose weight without losing power.
  • Athletes desiring to maintain a higher level of fitness during the post-season can adjust their weekly training to minimize or eliminate the drop in fitness that normally occurs during the transition period.
  • Athletes can tailor the frequency of rest weeks to suit their physical and mental fortitude. Some athletes may be able to handle a decrease in the frequency of rest weeks during the base cycle, and a few may even have the resilience to eliminate rest weeks entirely. Other athletes may determine that more frequent rest helps prevent bigger setbacks such as illness and injury.
The use of power-based metrics to develop annual training plans still requires the same level of attention to detail and to the “art” of coaching that is required of any other training plan method, and the metrics used are certainly not flawless indicators of an athlete's fitness or perfect predictors of an athlete's performance in races. However, they do provide a more effective means of gauging athlete development and managing an athlete's preparation for key events than more traditional methods such as total time and total distance. As power meters become more ubiquitous, not only among professional and amateur racers but also among serious recreational riders, using power-based metrics has become a viable and effective method of training plan development and deserves a place in every coach's repertoire.

Eating Protein and Fighting Aging

Peaks Coaching Group Eating Protein and Fighting Aging
Protein gets way less bad press than fats or carbs. Sometimes I think it gets too much good press, actually, like with the super high protein diets that are promoted for weight loss. The truth is that protein is very important since it supplies the building blocks for just about every tissue in your body. It also helps with recovery after workouts and satiation after meals, helping you to stave off hunger until the next meal or snack. However, loading up on excess amounts (beyond what your body actually needs) isn’t going to help out your health or fitness. I think people forget that excess protein can be stored as fat, just like excess carbs or dietary fat.

I once read a statement in SCAN’s "PULSE" newsletter that caught me off guard. The comment was regarding protein intake after exercise as it relates to muscle repair, which it said “could make a meaningful difference over the course of a year, particularly for athletes over 30 years old who slowly lose muscle as a normal part of the aging process.” Well, crap. I feel I handled my thirtieth birthday relatively well, mostly by ignoring the fact that I'd entered this decade in life. I’ve always said age is just a number anyway. But this comment bothered me. Whether I tell myself I have the fitness of a 22-year-old or not, the reality is that my body is over 30, and apparently that means I’m losing muscle mass. Another joy of aging! So I’ll do my best to fight it.

Here’s my plan and how you can do it too: getting enough total daily protein, incorporating optimal amounts of protein post workout, and strength training regularly.

Post-Workout Protein Recommendations

According to the article (and many others on the same topic), eating optimal amounts of protein shortly following a workout can help speed recovery and prevent muscle loss, since post exercise not only do the muscles need protein but they're primed and ready to utilize it. There isn’t a lot of good data that suggests that one protein type is significantly better than another (i.e. whey, casein, soy) so pick the one you like best. If you like it, you’ll be more likely to be consistent with consuming it. Generally it’s recommended to consume 10-20 grams of protein in the recovery window (within 30-60 minutes post workout).

Daily Protein Recommendations

Another key point the article (which was based on a recent study) suggested was that the optimal amount of protein at meals for athletes is about 30 grams. Beyond this amount there are no additional health benefits, and you run the risk of storing the excess protein as fat. Fall significantly short of this number and your muscles may not be getting as much protein as they need, which means you could lose muscle mass. The 30-grams-per-meal recommendation actually equates to a higher daily protein intake than what typical recommendations have called for (depending on body weight), which this study did not factor in.

According to traditional guidelines, the minimum amount of protein necessary to prevent deficiency is 0.8 grams per kilogram of body weight per day (0.36 grams per pound of body weight). That equals 49 grams for a 135-pound person. However, that’s the minimum to prevent problems; if you're an athlete you definitely need more. The typical recommendation for endurance athletes is to consume 1.2-1.4 grams of protein per kilogram of body weight per day (0.54-0.64 grams per pound). A 135-pound runner, for example, would need about 73-86 grams of protein a day, slightly less than 30 grams x 3 meals. Strength athletes need more: 1.4-1.7 grams per kilogram of body weight per day (0.64-.77 grams per pound).

Whether you go with the body weight recommendation or the 30 grams X 2 meals, these protein levels are not difficult to obtain if you are a meat eater. The key is to space your protein intake more evenly throughout the day, as it’s likely that your breakfast falls short. An egg, for example, has 6 grams of protein, while a 6-ounce steak has about 42. Vegetarians will have to work harder to make sure they meet their protein needs. It’s okay to add a protein powder or bars as a supplement if you aren't getting enough protein from food alone, but aim to meet your needs from food first, supplements second. Some good sources of protein are lean meats, chicken, fish, eggs, soy, dairy, nuts and nut butters, seeds, and beans.

So there it is: my plan to fight the aging process. Obviously it’s more complicated than this, but it’s a start. Wish me luck!

The Power of Big Data

Peaks Coaching Group Power of Big Data

One of my favorite magazines is Wired, which is all about technology. Almost every issue contains some sort of article on human performance, which makes sense when you think about it; after all, pretty much all technology in the world exists to improve human performance in one way or another. From your cell phone to a CAT scan machine to the voice-activated GPS in your car, technology helps us improve ourselves, our effectiveness, and our productivity.

Several years ago Wired published a story by Chris Anderson entitled, “The Power of Big Data” with the subtitle “The End of Science.” The introduction read, “The quest for knowledge used to begin with grand theories. Now it begins with massive amounts of data. Welcome to the petabyte age.” Anderson welcomed us into the age where a massive amount of data thrown at any problem will eventually lead to meaningful and significant answers, the age where computers crunch more numbers than ever and algorithms applied to any large enough data set give us the correlations and patterns that science cannot. It’s this sheer quantity of data and the ability to process it that Anderson argued is the reason for the end of the traditional scientific method of hypothesize, model, and test.

This article really hit home for me, since the amount of power meter data we collect grows with each ride, each month of rides, and each year of rides. The power of big data really makes a difference for a power meter user. When taken alone as a few data points here and there, your watts or cadence data cannot provide you with any new insight. When you start to capture data every second of every ride, ranges of time become more and more interesting. A whole record of your workout starts to become recognizable as you point out the hills you went over, the attacks you made, or the intervals you did. You can compare sections within a workout to help determine whether you should have done five or six intervals or held a higher cadence, etc.

This ability is very enlightening. I’ve mentioned many times that I believe a power meter satisfies two of our primal desires as humans: First, it gives us a way of looking at our workout history and reliving our experiences. We all like to relive the “good old days” and talk about the time Bob attacked up that hill and then the yappy dog jumped out from behind the bush, bit Bob’s tire, and got stuck in the wheel going flop-flop-flop like Wile E. Coyote on Saturday morning cartoons. This reliving of experiences is made even more permanent by having a power meter file of your ride; it’s like having a second-by-second diary of your entire workout or race.

The second desire a power meter helps satisfy is the desire to learn from our experiences. With the power of big data at our fingertips, learning from our rides becomes more and more viable. The more data we have, the better. Even just looking at one individual workout and comparing intervals to each another allows us to learn from them.

The power of big data becomes even more valuable when we put it together over a longer period of time, or when we collect more data, making the data set even larger. An individual ride is great, but a week of rides is better, a month even better than that, a year even more so. Multiple years of data are amazing. I have one client who has used his SRM since 2003 and religiously recorded every single ride he’s done, which makes his data set quite large and highly valuable for analysis purposes. As his coach, I’ve been able to track and direct his progress over the years, learning about his specific responses to his training dose, pinpointing the type of training that brings him into form, and knowing with a high degree of certainty that his current training is correct. This sort of knowledge is priceless, and it’s not something coaches or athletes had been able to ascertain before power meters. Only with big data have we been able to make sense of the hundreds of rides athletes have done over time.

Let’s look at an example. In the screenshot below you can see an athlete’s mean maximal power curve over several years, which is one of my favorite ways to view changes in physiology over a long time period. There are two lines; the solid black line represents the athlete’s best numbers from all his rides in his current year, and the dashed line represents his best numbers from all his rides in the previous year. When TrainingPeaks WKO+ software goes through every workout for the time period, compares it to every other workout, and looks for the very best wattage values for each time period, the power of big data really starts to shine. The shape of the curve in the mean maximal power curve tells us about the athlete’s strengths and weaknesses, and by comparing curves from two time periods we learn how each physiological area has changed.

If you’ll look closely, you’ll see that the solid black line (current year) is above the dashed line in many places, indicating that the wattages were higher during those time periods and proving substantial improvement. When the more recent line is higher than the second line only in certain places, we can see points of specific physiological areas that have improved. Maybe your power at VO2Max improved or your sprint improved or your functional threshold improved. By analyzing lots and lots of data, you can see these trends and review the truth about what is really happening with your fitness.

Let’s look at another example of the power of big data. In this example we’re looking at the mean maximal power periodic chart, which shows your peak watts for specific times that you select. These are then charted over whatever time period you want to see, such as your current and previous seasons. In the chart below we see data for this athlete over a two-year period; by looking at the chart, it’s immediately obvious how much more consistent his wattage numbers are in the current year and how clearly he progressed throughout the season. Especially notice the steady progression of the green line and blue line (his one-minute and five-second bests), which relate to the anaerobic capacity and neuromuscular power systems, respectively. When all of the best wattages are charted for each week over a year or two of data, it’s much easier to see changes to the training regime, incremental improvements, and new personal bests.

The chart below is from the same athlete, but it includes only his data from one month, which is a smaller slice of the data set. We see that it looks like the one-minute (green) line and five-minute (red) lines have decreased, while the five-second (blue) line and sixty-minute (black) lines have increased.

Without a larger view and data set, true increases and decreases in wattage are hard to see. Since fitness changes over a longer period of time than just four weeks, it’s hard to say what’s going on by looking at only these numbers. Referring back to the year comparison allows you to see the bigger picture, the forest above the trees. That’s the power of big data.

When we combine the incredible number-crunching power of personal computers with the ability to record incredible amounts of data, the power of big data really does start make sense for us lowly cyclists. We aren’t curing cancer, calculating satellite orbital trajectories, or creating world peace, but cycling gives us that sense of personal satisfaction that is hard to find in other places in life. Using a power meter to help remember your experiences and learn from them can be deeply satisfying, while the power of big data can help you become even more successful.

Review: ErgVideo's Alpe d'Huez Goodness

If you're a regular reader, you know we've been a big fan of ErgVideo since the beginning. So when ErgVideo founder Paul Smuelders approached us last year to film some new videos focused on specific winter training, we jumped at the chance. This year Paul asked us to send him a handful of PCG kits to outfit his team of riders for some filming. We gladly agreed, but we never imagined they'd show up in eye-popping 1080p Alpe d'Huez video! Putting that out right here at the front gets the disclaimer out of the way: yep, we are biased. We love ErgVideo.

Winter Power Training

Peaks Coaching Group Winter Power Training Hunter Allen

We say it all the time, but it's still true: what you do this winter really can make or break your season next year. There are some vital components to creating a very good winter training program, and of course using a power meter is a big part of it. Once you're rested from your season's work, recharged, and ready to go, your winter should contain at least two important components: (1) focused indoor training workouts using wattage and cadence and (2) solid workouts in the sweet spot zone.

Winter Hydration

Peaks Coaching Group Winter Hydration

It’s an easy mistake to make: not hydrating enough during winter workouts. The colder weather tends to dull our sense of thirst, plus water is less appealing in the cold. We also typically don’t sweat as much. So it’s easy to assume you don’t need much water (if any) during a cold weather workout, but you do! If you're overdressed, you may be sweating even more than you would during a workout in warmer temps. Your body also loses fluid through respiration, which is magnified with heavy breathing in the cold.

So who cares? Well, hopefully you. Studies have shown that more than a 2% loss of body weight from fluids can hamper performance. Not to mention the fact that water is an essential nutrient to the human body, involved in 98% of all bodily reactions. You may feel physically unwell if you are chronically dehydrated.

So how do you know if you're dehydrated after a workout? You may be able to tell by the color and volume of your urine; if it’s dark and concentrated, you're likely dehydrated. And if you have barely any urine to expel despite not peeing in a long time, you are definitely dehydrated! Ideally your urine should be almost clear to pale yellow. (Some vitamins and foods can alter the color of your urine, however, so if you're taking supplements, be aware that they may be part of the discoloration. The same is true with beets and beet juice, which can turn your urine pink!) Another tip-off for dehydration after a workout is feeling more tired or fatigued than usual. If the dehydration is extreme, you may feel dizzy or nauseous.

How much water do you need during cold weather workouts? Recommendations vary, but you generally should drink 6-12 ounces every 15-20 minutes (18-48 ounces per hour) during exercise. That’s a pretty wide range, I know. You don’t want to over-hydrate, either, or you'll risk uncomfortable stomach sloshing, excessive bathroom breaks, and even dangerous hyponatremia (salt deficiency) in rare cases.

The best way to figure out how much fluid you specifically need is by doing a sweat rate test. To do this, weigh yourself naked before your workout, then complete a 60-minute run or ride without eating or drinking anything during the activity. Don't use the bathroom, either. Once your hour is up, immediately weigh yourself again (again naked). The difference between your starting and finishing weights (remember there are 16 ounces in 1 pound) is your sweat rate in ounces per hour. For instance, if you weigh 1.5 pounds less after a 1-hour run, you should aim to drink 24 ounces per hour (16×1.5= 24). If your workout will last longer than 60-90 minutes, consider adding a sports drink for carbohydrate and electrolyte replacement, but water is enough for anything shorter.

Keep in mind that your sweat rate will be slightly different during different conditions, at different intensities, and during different activities, so you may want to do this test several times under a variety of conditions. For instance, if you're at altitude (as in, say, cross country skiing), you need even more water than at lower elevations. At the very least do the sweat rate test once in the summer and once in the winter so you can pinpoint differences in your sweat rate between the seasons.

Are you struggling to meet your fluid needs now that you know them? Try using room temperature water during workouts, since cold water is certainly not appealing when your body is already cold. Adding flavor can sometimes help make water more palatable, so try throwing a lemon wedge, cucumber slice, or splash of sports drink into your bottle. You can also use warm beverages like hot chocolate or soup broth for your post-workout fluid replacement (or even during your workout, if your stomach can handle it). Try taking small, frequent sips instead of chugging a bunch at once. It might help initially to set a goal and keep an eye on your watch; for example, you might commit to taking a couple of sips every 5 minutes.

It’s also important to maintain good hydration throughout the day. You may have heard the “8 glasses per day” (64 ounces) recommendation, but that’s not enough for everyone. To roughly calculate how many ounces of fluid you need per day, measure your body weight in pounds and divide it in half. That number in ounces is about how much water you need just for daily life, not including exercise. For example, a 135-pound athlete would need about 67.5 ounces a day, and more for exercise. But that’s just a rough estimate. Again, one of the best ways to know if you're hydrated is to pay attention to your urine color; if it’s anything other than pale yellow, you need more water. If you can smell it, you really need more water! Go drink up.

Happy hydrating!
