A simple oblique abdominal exercise.
Lie supine on a mat or on the floor with your knees bent. Place the band around your upper back, holding the handles or ends of the tube in both hands and push your hands up toward the ceiling.
Exhale, pull your navel in, and lift your shoulder blades off the floor slightly. As you come up, reach both of your hands toward the outside of your left knee. Inhale and lower your shoulders and head back to the floor. Repeat 15-20 times, rest, then switch sides.
