Quick backstory: A few years ago I was overweight, sedentary, and completely disconnected from my health. I signed up for a 7-month fitness transformation program and it changed everything. Lost the weight, got into ran a half marathon, and became the person who wears both an Apple Watch AND a Whoop daily (yes, both wrists).
That journey taught me something: the hard part isn't collecting health data. It's knowing what to do with it. I'd stare at HRV graphs and sleep scores and still not know if I should push hard or rest.
I've been obsessed with health data for years. I wear both an Apple Watch and a Whoop every single day. I track sleep, HRV, resting heart rate, training load and more.
