Bro, I track mine with Apple Watch, and it’s decent. Not Whoop-level, but it’s enough to tell me when I’m cooked.
Once you start noticing patterns like how crappy sleep tanks your lifts you’ll be hooked. Data doesn’t lie, bro.
Been thinking about grabbing one too. Sometimes I wake up feeling like I barely slept but the data says my sleep’s "fine" I trust how I feel more than the numbers but having sleep data does help give a clearer picture of your recovery. The Whoop and Oura both track heart rate variability and recovery so you get a better idea of how your body’s handling stress but at the end of the day you know your body best. If I’m dragging even if it says I got enough rest I’ll adjust my training or focus more on recovery that day. It’s all about using the data as a tool not a rule**
