I have very few problems with Whoop recognizing short spikes if I’m using the bicep band.
Here’s my tour so far:
I think what I’ve found with almost a year of Whoop (I was bored at the start of COVID :P) is that while it doesn’t correlate very well to how I “feel” (that is usually dictated by number of sleep disturbances) it does correlate highly to how deep I can go.
Case in point that I’ve noticed with Sufferfest - if I have a recovery score > 70% then typically I notice my heart rate doesn’t get up to LTHR as fast, and that it is way more ‘reactive’ in terms of dropping down faster to Z1 during a recovery period. So I do find some truth in the “I can go harder when I’m well recovered” on a green score, even if I wake up feeling like poop because I slept well.
In terms of recovery during the tour - I always stretch down right after rides (mix of static stretches and sun salutations) and then have been rolling out legs with a lacrosse ball in the evening before bed. Both of those have left me with semi-functioning legs!
