HOW TO DO SIT-UP
- Lie on your back with knees bent, feet planted, and arms crossed over the chest or reaching forward.
- Exhale and curl the trunk from the floor, then continue flexing at the hips until the torso is upright.
- Reverse the movement under control and lower the spine without dropping.
- Avoid pulling on the neck or using a fast arm swing.
- Anchor the feet only if that matches the intended variation, and choose a crunch or reduced range if repeated flexion or hip-flexor work is uncomfortable.
