Weights pre-fill from your last session + the progression rule. Override anything.
Exports every saved session as a readable log + machine-readable data. Paste it back to me, or download the file and drop it in chat.
Breathing: exhale-brace every rep. No Valsalva. No belt for the first 4 weeks.
Every working set leaves 2–3 reps in the tank. No grinders. No 1RM. Ever. If a squat day bothers the SI joint, sub the front squat (drop 20 lb).
