Ball back extension

Face down over a stability ball with the feet on the floor, the trunk rises from draped over the ball until it is in line with the legs: the NSCA's beginner back extension, which on the ball worked the extensors no harder and loaded the spine less than on a mat. A plate held at the chest makes it heavier.

How to move

  1. Lie face down over a stability ball, the hips and lower belly on it and the balls of the feet pressed into the floor behind.
  2. With the hands behind the head, raise the trunk until it is in line with the legs.
  3. Hold, then lower slowly over the ball.

Form cues

  • Rise only to a straight line, not past it.
  • Widen the feet for balance.

Practice and cautions

No universal dose is assigned. Choose a manageable amount for your current capacity, leave room for controlled repetitions, and allow recovery. A clinician’s individual plan takes priority.

With osteoporosis, start with the back flat on the ball rather than draped over it. This is movement education, not an assessment or treatment prescription. Stop for sharp or increasing pain, dizziness, numbness or tingling; seek individual guidance for symptoms, injury or restrictions.
