The evidence, written plainly.

Sauna and cold, ranked by evidence — not by podcast

Heat has a 21-year Finnish cohort behind it. Cold has small soreness trials and a documented bill after lifting. Here's what the literature actually supports, and in what order to care.

Stress is a training load

A brutal work week slows the same recovery your squats depend on — measurably. One ledger, one column, and the arithmetic for adjusting a program around a loud life.

HRV: what your watch is actually measuring

The gaps between your heartbeats, the math your watch runs on them, and why the number only means something compared with your own baseline.

Sore or hurt? What DOMS is, and when pain means stop

The soreness schedule, why the first session back bites hardest, and the plain difference between sore and hurt.

Rest days: how many you need, and what counts as rest

Recovery is per-muscle, not per-body — how to space hard sessions, and why a rest day doesn't mean the couch.

The recovery hierarchy, ranked

Where sleep, food, massage, and the cold plunge actually land — ranked by evidence, not by feed.
