Sit-Up
Knees bent, feet down: curl all the way up until the torso is vertical, then lower under control.

How to do it
Setup
Knees bent, feet flat, hands at the temples or crossed.
Steps
- Curl all the way up to a vertical torso.
- Keep the feet down without an anchor if possible.
- Roll back down vertebra by vertebra.
Common mistakes
Yanking the neck: hands rest, chest leads. Feet flying up: slower curl or a light anchor while learning. Flat-back plopping: the roll is the safety.
Breathing
Exhale sitting up, inhale rolling down.
