Daily base

Every morning, ~8 minutes. Three descending sets. Each rep is a 10-second hold, not a repetition — so “5 / 3 / 1” means five holds, rest 20–30s, three holds, rest, one hold.

Stop rules

Symptoms below the knee, numbness, foot weakness, or any bowel or bladder change means an appointment — not a program tweak.

First Sunday of the month: Sørensen hold (target 3–4 min) · side plank left vs right within 5% · re-film box squat depth · review the tweak log.
