How to perform Kneeling Cable Crunch With Alternating Oblique Twists

  1. Connect a rope attachment to a high pulley cable and position a mat on the floor in front of it.
  2. Grab the rope with both hands and kneel approximately two feet back from the tower.
  3. Position the rope behind your head with your hands by your ears.
  4. Keep your hands in the same place, contract your abs and pull downward on the rope in a crunching movement until your elbows reach your knees.
  5. Pause briefly at the bottom and rise up in a slow and controlled manner until you reach the starting position.
  6. Repeat the same downward movement until you're halfway down, at which time you'll begin rotating one of your elbows to the opposite knee.
  7. Again, pause briefly at the bottom and rise up in a slow and controlled manner until you reach the starting position.
  8. Repeat the same movement as before, but alternate the other elbow to the opposite knee.
  9. Continue this series of movements to failure.

Form tips

  • Brace as if about to take a light punch and breathe shallowly — don't hold your breath for the whole set.
  • Keep tension on the cable through the whole range — pause before the stack touches down instead of letting it crash.
  • Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
  • Stop a rep or two short of failure on most sets to keep form clean and recover faster.

Common mistakes

  • Cranking with the hip flexors or neck instead of moving from the trunk.
  • Letting the stack yank the working muscle back at the end of each rep.
  • Chasing weight jumps before the current load feels solid on every rep.
