Over the past few years, tech companies have increasingly been flexing their muscles and showing off innovations that can help people eat better, sleep more soundly, and work out smarter. What differentiates the WHOOP from just about every other fitness tracker is that it focuses specifically on fitness output and recovery. The always-on wristbands they just look like a fabric watch bands, BTW measure heart rate, heart rate variability HRV , and sleep. This is different than your heart rate, which measure beats per minute versus HRV which tells you the variation between the beats. And he was right, I felt fine when I fitnessed, but was I recovering? Eh, hard to know. Like oh, you want to know how stressed I am? You want to know how if I fell asleep with a book in my hands? Truthfully, it was stunning how closely the data matched what I felt. When I felt crappy, it told me my recovery was crappy.

Wearable companies don't always make it clear for users, especially casual ones, what they can actually do with the data they collect—which is why the estimated abandonment rate for wearables was around 30 percent at one point a few years back. High level users and serious athletes can do a little more with their data, but without professional help, the question still remains. Whoop, a brand that has put arguably the highest level of wearable tech smarts on the mass consumer market, has continually made it easier to answer that 'why' question. The company's wrist strap is designed only to inform its wearer how close they are to peak performance, and how much rest and recovery is needed to get them there.
