Pattern
Lateral flexion
Setup
- 01Sit on a bench or chair placed with one side close to a wall.
- 02Sit tall with the head, shoulders, and upper back lightly touching the wall.
- 03Place the fingertips behind the ears with elbows wide.
- 04Brace the trunk and keep both hips planted on the seat.
Execution
- 01Slide the torso down toward one hip, bending sideways along the wall.
- 02Crunch the ribs toward the hip on the working side.
- 03Pause briefly at peak contraction of the obliques.
- 04Return to tall sitting under control and repeat, then switch sides.
Checkpoints
- -The wall contact keeps the movement in a pure side-bend plane.
- -Both hips stay planted; the pelvis does not hike.
- -Ribs move toward the hip rather than the elbow diving forward.
- -The return to upright is controlled, not a rebound.
Common mistakes
- -Twisting forward off the wall instead of bending sideways.
- -Lifting the opposite hip to fake a bigger range.
- -Pulling on the neck with the hands.
- -Rushing the reps and losing the peak squeeze.
Programming notes
- -Use 2 to 3 sets of 10 to 15 reps per side.
- -Add a slow 2 second squeeze at the bottom before adding any load.
- -Pairs well after a heavy anti-rotation or carry exercise for the obliques.
