How to Do the Plank

  • Stand on your elbows and feet.
  • Brace your abs, and try to form and hold a straight line from your head to feet.


The plank is a bodyweight exercise to strengthen your abdominals. The exercise can be made more challenging by placing your hands or feet on an unstable surface (such as a Bosu ball, balance board, or in suspended rings), or by placing a weight on your back.
