Crossbody Crunch to Leg Extension

  • Lie flat on the floor with your lower back pressed to the ground. Place your hands behind your head.
  • Bend your left knee and bring your right elbow up, as though the two would touch. For an extra challenge, lift your right leg and keep it suspended a couple inches above the ground.
  • Keeping your right elbow in place, extend your left leg out, then bend it again, bringing it back toward your chest. This is a unilateral exercise.
  • Do three sets of 10 reps on each side.
