How to

1. Start on your back, holding a Pilates ring or squishy ball to the ceiling with the legs in table-top

2. Exhale to curl up with the body and twist to one side, extending the opposite leg

3. Inhale to alternate to the other side. You want to tap the opposite arm to the bent leg and straighten the other leg, hovering it above the mat.

Keep it quick and dynamic without pauses

Tip: To make this exercise harder, keep legs straight and scissor them, twisting towards the leg stretched up to the ceiling

Reps: 8 to 10 each side
