This movement intensifies the traditional mountain climber by adding a core rotation to isolate the obliques. Perform the exercise in a slow, controlled manner to sculpt your core and fire up your entire body.

1 Begin in a high plank position with your shoulders above your hands and your toes hip-width apart. Distribute your weight evenly between your toes and hands. Inhale.
2 Exhale, and use your core to pull your right knee across your body, towards your left elbow. Maintain a stable upper body and keep your shoulders above your wrists.
3 Inhale and return your right foot to the starting position. That is one rep.
4 Exhale and repeat with your left leg. That is another rep. Alternate rotating to each side for the number of reps given in your workout.
