체크포인트

• -The leg stays passive; no kicking or helping upward.
• -The elbow stays braced against the thigh as a pivot point.
• -Torso stays upright rather than heaving backward.
• -The tempo stays slow enough to feel a continuous contraction.

흔한 실수

• -Lifting the leg with the hip flexors instead of the arm.
• -Rocking the torso back to create momentum.
• -Gripping too low on the leg and straining the fingers.
• -Rushing reps so tension never accumulates.
