WHOOP SLEEP

WHOOP SLEEP

HOW MUCH SLEEP DO YOU REALLY NEED?

Science tells us that you don’t get stronger in the gym (that’s what breaks you down), you actually get stronger during rest. Sleep can be the forgotten third of your life. It’s the period to repair, regenerate and prime your mind and body for peak performance. WHOOP measures not only how long you sleep, but the time spent in each stage to better understand sleep quality. The WHOOP Sleep Coach tells you exactly how much sleep you need to reach your desired performance level the next day.

SLEEP GOALS

SLEEP GOALS

Quality

See how much time you spend in each sleep stage: Light, REM, Slow Wave (Deep), and Awake. A good sleep includes 3-5 cycles.

Efficiency

WHOOP calculates the numbers of disturbances during your sleep, and gives you a percentage from 0-100% on how efficiently you slept. More frequent disturbances are associated with lower sleep quality.

Consistency

Science shows that the more consistent you are with your sleep and wake times, the better sleep you'll get. The WHOOP Sleep Coach makes recommendations that match up with your circadian rhythm to achieve higher consistency.

WHOOP RECOVERY

WHOOP calculates your recovery based on 4 physiological markers: Heart Rate Variability (HRV), Resting Heart Rate (RHR), sleep, and respiratory rate. These metrics are calibrated to your baseline, which means your recovery is personalized each day.

WHOOP RECOVERY

WHOOP calculates your recovery based on 4 physiological markers: Heart Rate Variability (HRV), Resting Heart Rate (RHR), sleep, and respiratory rate. These metrics are calibrated to your baseline, which means your recovery is personalized each day.

HEART RATE VARIABILITY (HRV)

HRV measures the variation in time between each heart beat. Leading exercise physiologists agree that HRV is one of the most useful tools for determining optimal training loads.

RESTING HEART RATE (RHR)

WHOOP measures your RHR during your deepest sleep each night for consistent, controlled readings. Over time, you can monitor changes in RHR as you navigate training cycles.

SLEEP

Get unprecedented insight into your sleep, including sleep cycles, disturbances, respiratory rate, circadian rhythm, and more. Every night WHOOP tells you exactly how much sleep you need, so you can function at your best the next day.

RESPIRATORY RATE

Studies show a clear link between changes in respiratory rate and symptoms of illness and health complications. WHOOP monitors respiratory rate each night and notifies you of significant changes.

DO YOU KNOW HOW RECOVERED YOU ARE?

Recovery isn’t just about how you feel; it’s about what’s happening to your body as it adapts to training and other stressors. Have you ever noticed that you feel great one day, but your performance is weak? WHOOP takes the guesswork out by giving you quantified recovery metrics, so you make informed training decisions each day.

WHOOP STRAIN

WHOOP STRAIN

MEASURE EVERY EFFORT

Every heartbeat and every hour counts. By wearing WHOOP 24/7, you’ll get feedback on every moment of the day, whether you’re exercising, resting, or going about your daily life. Your strain will reveal how your body is responding to things like stress, travel, and work, so you can make smarter decisions when it comes to recovery.

TRAINING OPTIMIZATION

Your strain is a measure of the cardiovascular load your body takes on over the course of a day or during a given activity. WHOOP calculates your exertion and quantifies it on a scale from 0-21. Maximize the efficiency of your training by balancing your Day Strain and Recovery, and see your body evolve by comparing Strain for similar workouts over time.

OPTIMAL TRAINING

The perfect balance of pushing your body to improve without burning out.

OVERREACHING

With too much load, in time extra training can be more detrimental than helpful.
