Machine Crunch
Seated against the pads, curl the ribs toward the pelvis against a set weight.
How to do it
Setup
Seated, chest or shoulders against the pads, feet hooked.
Steps
- Curl the ribs toward the pelvis against the weight.
- Squeeze at the full curl.
- Return until the abs stretch, no stack rest.
Common mistakes
Pulling with the arms on the pads: they only rest there. Hips lifting into the curl: seated stays seated. Racing: slow curls beat heavy jerks.
Breathing
Exhale on the crunch, inhale returning.
