Recovery, Sleep, and Wearables
Heart rate variability, sleep architecture, cold and heat exposure, and the wearables that track them. What's signal and what's marketing.
What this pillar covers
Recovery is the half of training where adaptation actually happens. Most lifters under-invest in it because the work is invisible. The wearable industry has converted that invisibility into a category — sometimes well, sometimes hand-wavingly. We pull apart what each metric measures, how reliable it is, and how to use the daily number without becoming a slave to it.
