Side Sit-Up
The oblique crunch with one hand behind the head: the knees dropped together to one side, the shoulders curl up off the floor.
How to do it
Setup
Lying on the back, knees bent and dropped together to one side, one hand behind the head.
Steps
- Curl the shoulders up off the floor, the chest leading.
- Pause at the top with the knees still down to the side.
- Lower slowly; finish the side, then switch the knees and the hand.
Common mistakes
Pulling the head up with the hand: it only rests there; the ribs lead. Knees lifting as you curl: keep them stacked on the floor. Sitting up too far: a short curl keeps the obliques working.
Breathing
Exhale on the crunch, inhale lowering.
