Machine Total Abdominal Crunch
Seated in a total-ab machine with the hands on the overhead handles and the ankles behind the rollers, curl the chest down as the seat tips the knees up to meet it.
How to do it
Setup
Seated, the ankles behind the lower rollers, hands on the handles by the head, back against the pad.
Steps
- Curl the chest toward the knees as the knees rise with the seat.
- Squeeze the abs where the two meet.
- Return to upright under control, the stack not touching down.
Common mistakes
Pulling the handles down with the arms: they hold still; the abs curl. Letting the weight yank you back: resist on the way up. Kicking the seat up with the legs: the knees rise with the curl, not before it.
Breathing
Exhale on the crunch, inhale on the return.
