Comparison
Loadcast or WHOOP if you run and lift?
WHOOP is a screen-free band you wear around the clock, and it says it measures strain and recovery and gives you personalized coaching. Loadcast decides each day from the sessions you logged, and it counts lifting as load on the same legs you run on.
