WHOOP! We talk HRV, sleep, strain and recovery from our team Craig (cycling), Luke (running) and Tommy (Crossfit)

Send us Fan MailWhoop - the wearable fitness/health tracking device worn on the wrist and claims, by them, to unlock your greatest human potential. We explain what is heart rate variability, in layman's terms and we pull apart the devices and its pretty slick app interface which gives you an in-depth understanding of your sleep, recovery and strain. We tackle this through the eyes of three different sports and athletes. Tommy is full on into crossfit and gets mega annoyed when a 45 min normal human breaking workout doesn't even beat a walk for 45 mi in terms of strain. Luke looks at it as a runner, when running is the quickest way to get high strain on the CV system. Lastly I look at it as a cyclist - cycling is the second easiest way to create strain.
