What's up, folks? Welcome back to the WOOP podcast. I'm your host, Will Ahmed, founder and CEO of WOOP, where we are on a mission to unlock human performance. That's right. We've got a groundbreaking research study on today's podcast. But first, a reminder, you can get 15% off a WOOP membership.

If use the code, Will Ahmed, that's WI-L-L-A-H-M-E-D. WOOP membership comes with hardware, software

analytics, and it's designed to help you improve your health. Now, this week, we're sharing
