This variation of a mountain climber targets your glutes as well as your core, including the obliques with the kick out. It's also a good cardio exercise when added into a high intensity interval.

Using a band around your knees, ankles, or feet during a crab walk is a great way to increase the difficulty of the exercise and add additional resistance training.
