The plank is a classic core-strength exercise with the fitness ball:

  • Lie on the ball on your stomach, with your feet touching the floor behind the ball. Lean forward until you touch the floor with your hands.
  • Walk your hands away from the ball until you feel the ball reach your upper thighs, as shown. Keep your feet suspended above the floor while you balance on your hands and on the ball. Keep your shoulders directly above your hands.
  • Tighten your abdominal muscles. Hold for three deep breaths or as long as you can maintain your balance and form.
  • Return to the starting position and repeat.
