BODY

A skill you are learning, one rung at a time. Calisthenics is the open path.

IT ASKS SIX THINGS, ONCE

Ten minutes. Whatever you score is the start — there is a rung for every result, including zero push-ups. Under every test there is I don’t know yet: take it and you start at the bottom, and in four weeks the retest finds out where you actually are.

THEN, EVERY DAY

One decision and its reason. A session, something smaller, rest, or nothing — and a rung will not open before the tissue has had time to catch up, however well it is going. That is the whole product; there is no feed under it.
