BOSU cable crunch

Abs

• Target muscles: abs, obliques
• Equipment: gym machine
• Level: advanced

How to do it

1. Attach a handle to the low pulley of a cable crossover station and lie back on a BOSU ball, head toward the machine.
2. Bend your knees, plant your feet on the floor, and grip the handle with both hands, holding it at your lower abdomen.
3. Brace your abs and crunch your torso up, lifting your shoulder blades off the dome and rotating your shoulders slightly to one side.
4. Hold briefly at the top, the pull coming from your abs, not your arms.
5. Slowly lower back down onto the dome, keeping tension on the cable.
6. Repeat for the desired number of reps, then switch the rotation side.
