Hanging Leg Raise

You swing the legs up with momentum and let the body pendulum between reps.

You lift the legs with the hip flexors only, never curling the pelvis so the abs barely work.

You drop the legs fast on the way down instead of resisting the descent.

Think about rolling your belt buckle up toward your ribs, not just lifting your feet.

Kill all swing by pausing a beat at the bottom of each rep.

If straight legs force you to swing, bend the knees and do the movement strictly instead.
