Before WHOOP, I didn’t know my body struggled to acclimate to different time zones. After realizing that, I changed my travel schedule to Olympic Trials and because of that I crushed it on the first day.

I realized shortly after getting the whoop that my habits surrounding sleep were horrible.
 I was getting next to no REM sleep, and Whoop helped me fix that. I realized that my nightly glass of wine or beer was wreaking havoc on my sleep, and without Whoop, I would not have understood this, and without understanding, there is no action.”

Patrick McNally
Coach, CycleAnalyze

On the road to Rio, Whoop was a critical part of my recovery. There were so many distractions, fatigue, stress, training and family to juggle.

Whoop is one of the most important pieces when putting a performance goal in front of you.
