Abs

Cable Crunch

The cable crunch is a kneeling crunch with a rope: your abs work against a load you can add to like any other exercise.

Setup

Clip a rope to the high pulley and kneel facing it. Hold the ends beside your head. Hips over your knees, thighs still.

Kneel below the high pulley, holding the rope ends at your face — starting position.
Exhale and curl down, bringing your elbows toward your thighs using your abs, not your arms.
Inhale and return to the starting position.

Sitting back onto your heels by bending at the hips — your thighs stay put, only your spine curls.
Pulling with your arms — the rope stays by your head, your abs pull.
Going too heavy — if you can't round your back, your arms and bodyweight are doing it.
Letting the weight yank you up — come back slowly.
