A stability ball adds an unstable surface that challenges balance, coordination and the smaller muscles that support larger movements. The original selection includes:

  1. Wall squat
  2. Single-leg wall squat
  3. Balancing reverse lunge
  4. Balancing push-up
  5. Plank to pike
  6. Ball pass
  7. Balancing oblique crunch
  8. Glute bridge to hamstring curl
  9. Lower-back extension

Use a clear area, choose the right ball size and progress from stable variations before adding speed or range.
