Has your back cramped after a long day at your desk? This exercise helps.

Instructions

  1. 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.

  2. 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.

  3. After 8-10 repetitions go back to the starting position. Take a short rest, then repeat the exercise sequence once or twice.
