After analysing data from thousands of Whoop users — including elite athletes — Kristen Holmes (@TheLine-Podcast) proves that bypassing your natural pressure for sleep comes at a massive cost to recovery, HRV, and performance.
You’ll hear why perceiving your day as threatening instead of challenging destroys your sleep quality, how Zone 2 training is actually a recovery modality (not exercise), and what happens when you fight sleepiness and get a second wind that crushes your melatonin and growth hormone release.
Tune in for her jet lag protocol, why meal timing matters more than most people realise, and the single behaviour that improves almost every health metric: consistent sleep timing.
