Myotatic Crunch on BOSU Ball
The BOSU crunch started from a full stretch: the arms reach overhead as the back lowers over the dome, then the trunk curls up.
How to do it
Setup
Lower back on the top of the BOSU dome, feet flat on the floor, knees bent, arms reaching overhead.
Steps
- Lower back over the dome until the abs stretch, the arms long overhead.
- Curl up from the stretch, the arms traveling with the trunk.
- Pause near upright, then lower slowly into the stretch again.
Common mistakes
Throwing the arms forward to get up: they move with the trunk, not ahead of it. Skipping the stretch at the bottom: the lowering over the dome is the point. Sliding off the top of the dome: keep the lower back centered on it.
Breathing
Exhale on the crunch, inhale on the stretch.
