Has your back cramped after a long day at your desk? This exercise helps.
- Lay on your back on a mat. Roll a stability ball under your thigh. The hands are placed with the palms up next to the body.
- With bent legs, try turning the ball slowly to the left and right, without the lower back or tailbone losing contact with the mat or floor.
- After 8-10 repetitions go back to the starting position. Take a short rest, then repeat the exercise sequence once or twice.
