Tuck Crunch
The crunch with the knees held up over the hips and the shins level, arms crossed on the chest; the raised legs keep the lower back pressed down.
How to do it
Setup
On your back, hips and knees bent to 90°, shins level, arms crossed on the chest.
Steps
- Curl the shoulders up toward the knees.
- Keep the knees still over the hips.
- Lower the shoulders slowly, the legs staying up.
Common mistakes
Knees swinging toward the chest to help: they hold still; the shoulders travel. Legs sinking toward the floor: keep the knees stacked over the hips. Arms coming off the chest: keep them crossed.
Breathing
Exhale on the crunch, inhale lowering.
