Get ready to obliterate your obliques with the ultimate core move. Mountain climbers are especially great because they also provide intense cardio. Start in plank position and prepare to burn some major calories.
- Engage your core.
- Explosively bring your right knee up toward your left elbow while twisting your obliques.
- As soon as you return your right foot to the floor, explode with your left leg, pushing your left knee toward your right shoulder. The movement and transitions should be fluid, without pauses, in this exercise.
- Aim to complete 10 reps on each side for a total of 20 reps. Rest and then do one or two more sets.
