Pattern
Loaded trunk flexion
Setup
- 01Attach a rope to a high pulley and select a moderate weight.
- 02Kneel facing the stack about one step back from the machine.
- 03Hold the rope ends beside the head or in front of the forehead.
- 04Set the hips slightly back and start with the spine long, abs stretched.
Execution
- 01Exhale and curl the spine down, driving the ribs toward the pelvis.
- 02Bring the elbows toward the mid thighs while the hips stay mostly still.
- 03Squeeze the abs hard in the fully rounded position.
- 04Uncurl slowly back to the tall starting position, feeling the abs stretch.
Checkpoints
- -The spine visibly rounds; this is deliberate flexion, not a hip hinge.
- -Hands stay fixed relative to the head for the whole rep.
- -Hips stay in roughly the same place instead of sitting back to the heels.
- -The return is as slow as the curl down.
Common mistakes
- -Hinging at the hips so the load moves without the spine flexing.
- -Pulling the rope down with the arms like a triceps pushdown.
- -Sitting the hips onto the heels at the bottom of every rep.
- -Loading so heavy that the range collapses to a few inches.
Programming notes
- -Use 3 to 4 sets of 10 to 15 reps and progress the stack like any other lift.
- -Small weight jumps preserve range; add reps before adding load.
- -One of the few ab exercises worth logging weight on long term.
