- Cross the arms over the chest or rest hands lightly behind the head.
- Brace the core and curl the spine up segment by segment toward the knees.
- Keep going until the torso is upright over the hips.
- Lower under control all the way back to the floor.
- Reset the brace before the next rep.
Watch for
- Pulling on the neck with the hands.
- Using momentum to launch off the floor.

Tip
Anchor the feet only if you cannot keep them down without it. Free feet bias the abs over the hip flexors.
