Cross-Body Crunch
Obliques, Abs


Core / Beginner / Compound (multi-joint)
A cable exercise for the obliques and abs, with the rear delts assisting.
Why it hurts: The lumbar spine is not built for much rotation, and repeated twisting under load irritates it.
✓ Instead: Let the hips and feet pivot and turn from the upper back and hips together.
