Starfish Crunch

Muscles worked: Abs & Core, Legs & Glutes · Also: Back, Calves

Starfish Crunch is a wide crunch: lying on your back with arms and legs spread out like a starfish, you lift one arm and the opposite leg toward each other, then switch sides.

The wide start position makes the core work to bring opposite limbs together, which adds a balance and coordination challenge. Reach diagonally with control, keep your lower back on the floor, and alternate sides evenly.

How to do it

1. Lie on your back with your arms and legs spread out like a starfish.
2. Lift one arm and the opposite leg toward each other in a diagonal reach, with control.
3. Lower back down and switch sides.
4. Keep your lower back on the floor throughout.
5. Reach diagonally with control and alternate sides evenly.
