Advanced plank - Core exercises with a fitness ball

Advanced plank

When you're comfortable with the plank, try the advanced plank:

• 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 (A). Keep your shoulders directly above your hands.
• Tighten your abdominal muscles.
• Push your body weight forward until your shoulders are in front of your hands and the ball is beneath your shins (B). Hold for three deep breaths.
• Return to the start position and repeat.
