Log heat training sessions manually and track thermal adaptation over time.

New heat training session

Z1Warm zone 1 — Minimal heat load. The body cools easily, ideal for recovery and light training.

Z2Warm zone 2 — Moderate heat load. Core temperature rises slightly while cooling still works well.

Z3Heat zone 3 — High heat load. This is the main sweet spot for heat training.

Z4Heat zone 4 — Extreme heat load. High risk for heat illness and rapid performance drop.
