Crunch with Legs on Bench
Abs


Core / Beginner / Isolation (single joint)
A cable isolation exercise for the abs.
Why it hurts: It becomes a hip movement and the abs do little.
✓ Instead: Keep the hips fixed and curl the ribcage down toward the pelvis.
How specific this exercise is to each movement.
