준비 자세
- 01Lie on your back with knees bent and feet flat on the floor.
- 02Place the fingertips lightly behind the ears, elbows wide.
- 03Press the lower back gently toward the floor.
- 04Keep the chin off the chest with eyes toward the ceiling.
수행

- 03Pause briefly with the obliques fully contracted.
- 04Lower with control and repeat to the other side or finish the set on one side.
체크포인트
- -The shoulder, not just the elbow, travels across the body.
- -Hands stay light behind the ears with no neck pulling.
- -The lower back stays connected to the floor.
- -Rotation happens at the top of the crunch, not as a flat swivel.
흔한 실수
- -Yanking on the head and neck to create the twist.
- -Flapping the elbow inward while the torso barely rotates.
- -Rushing reps so the obliques never get a full contraction.
- -Lifting the entire back off the floor into a sit-up.
프로그래밍 노트
- -Use 2 to 3 sets of 10 to 15 reps per side.
- -Slow the top pause to 1 to 2 seconds before adding volume.
- -Alternating sides each rep keeps tempo honest and even.
