체크포인트

• -Fingers actually reach the kneecaps on every rep.
• -Lower back stays in contact with the mat throughout.
• -Chin stays off the chest with a fist of space under it.
• -The movement comes from the trunk, not from yanking the arms.

흔한 실수

• -Pulling with the neck instead of curling the trunk.
• -Using momentum to swing up rather than a controlled curl.
• -Lifting so high that the hip flexors take over.
• -Letting the feet slide or lift off the floor.
