How to do it

Setup

  • Kneel facing a high cable with a rope, hands at the head/neck, hips back.

Execution

  • Crunch by rounding the spine toward the pelvis (the rope follows the head), squeeze the abs, control back up; flex the spine, don't just hinge at the hips.

Common Errors

  • Hinging at the hips instead of flexing the spine
  • Pulling with the arms/lats
  • Not rounding toward the pelvis
  • Coming up too high and losing ab tension

No-Fly Zone

under 5 reps (becomes a hip hinge / pulldown with the abs static)

What about supplements?

Train hard and hit your protein first — that's most of it. If the fundamentals are handled, two are worth it for building muscle:

Creatine

Monohydrate, 5 g/day. The most studied muscle supplement.
