Of all the features, Whoop 4.0 is most popular because of its applicability on various workouts. It automatically detects activities such as running or riding a bike, however, for specific gym exercises, it is best to upload your regime to the app to achieve the most precise results in workout logging. This can be seen as a drawback as it takes time to set up, but the advantage here is that you will be able to accurately track your workouts. In addition to this, if someone’s wearing a Whoop, their heart rate will be constantly monitored and that enables them to only work out at suitable heart rate zones. Only when doing outdoor runs, one regrettably cannot use the phone to check the data – therefore a smartwatch seems much more practical.
