Thigh curl

A thigh curl works on your glutes and legs.

1. Lay down on the floor.

2. Bring you legs up on the pilates ball.

3. Keep your shoulders down during exercise.

4. Bring your hips up while engaging your hamstrings.

5. Go slowly and controlled down to starting position again and repeat.

Make sure not to "hang" in your hips, as that can cause injuries in your back..
