Swiss Ball Plank

The ball plank is a version of the plank exercise which works the core and abdominal muscles. Performing it on a ball rather than on the floor adds an extra dimension of difficulty.

  • Lift the knees off the floor to support your weight between the toes and forearms.  
  • Try to keep a straight line between your ankles and shoulders.
  • Don't let your stomach and back drop down.  
  • Hold for as long as you can maintain good form.
