Is a WHOOP or similar biometric band worth wearing?
Answer
For a while it was, for me. Unlike most fitness bands the WHOOP is built around strain, recovery and sleep rather than around step counts, which makes it more like a mirror than a scoreboard: it tells you what yesterday cost you. I used its trend data to prepare for a 235KM ride. I have also written about why I later stopped using sensors altogether, and both positions are honest.
