How to Do a Plank With Clamshell

  • Lie on your left side with knees slightly bent and your elbow underneath your shoulder.
  • Press into your bottom forearm to lift the hips as high as possible, keeping your abs engaged.
  • Raise your top knee to open the thighs like butterfly wings, then slowly lower the knee, completing one rep. The move is similar to the clam.
  • Complete two sets of 10 reps on each side.
