Bodyweight Sit Up
A step-by-step form guide from the Ægir Iron exercise library: how to do the lift, what to watch for, and the muscles it trains.
- Equipment
- Bodyweight
HOW TO PERFORM
- Lie on your back with the knees bent and the feet flat on the floor, about hip width apart.
- Cross the arms over the chest.
- Curl the chin and shoulders off the floor, then keep sitting up until the torso is upright over the hips.
- Lower under control, rolling down through the spine rather than dropping back to the floor.
FORM TIPS
- If the feet lift off the floor as you come up, hook them under a loaded bar.
- Lead with the chest. Hands pulling on the head is how sit-ups strain the neck.
TARGET MUSCLES
Primary
- Abs
Secondary
- Obliques
