Steps:

1. Sit in a sturdy chair with your back straight or stand with feet hip-distance apart.
2. With arms shoulder distance apart, hold the band tightly in each hand.
3. Twist your body to one side. Keep your feet firmly planted on the floor or hips firmly planted into the chair. Picture your waist and back being wrung out like a towel.
4. Slowly come back to the center and twist the other way.
