You can also wear this Fitbit swimming (it’s water-resistant up for 50 meters). It also includes faves from the previous model like automatic sleep tracking intel, period and fertility insights, a long-lasting battery, and built-in GPS. New features include an on-wrist ECG app for heart health and EDA Scan app for stress management. The Charge 5 debuts a personalized 'daily readiness score' so you know if your bod is up for a sweat sesh or should log some recovery time. You don’t have to worry about forgetting to record your workout with this budget-friendly exercise buddy-it recognizes when you’re moving. 'It is designed simply, and it has a stretchy, comfortable fabric band and a rechargeable sensor that clips right on so you never have to take the band off.'īasically, if you're looking to optimize your training and recovery days and aren't as concerned with things like GPS or a big watch face, the Whoop tracker might just be for you. “I love that it gives you a recovery score to determine how hard you should train the next day.” “This is one of the most analytically accurate trackers!” says Roxie Jones, certified personal trainer. (A green circle means go for it yellow means proceed with caution red means take a rest day.) It’s also waterproof, and you still get your typical exercise stats, like calories burned. Whoop determines whether or not you're ready to tackle your next workout-or if you need more rest-based on your heart rate variability, resting heart rate, and sleep. In fact, it emphasizes what you do after exercising. It’s not just about calories or distance with this fitness tracker. It can also connect to Whoop Body, the brand's high-tech line of bralettes, underwear, performance tops, and leggings, for mobile and discrete tracking. It helps you understand when you’re making progress or if something’s off healthwise.

The 4.0 measures your blood oxygen levels, skin temperature, and heart rate. You can consider the fourth gen Whoop your own personal health and fitness coach that's conveniently available around the clock.
