MOUNTAIN CLIMBER ON BLACKROLL®
Hold the BLACKROLL® each side with one hand and come into a plank position. Place the BLACKROLL® underneath your shoulders and plant your feet on your toes, hip-width apart. Make sure that your body forms a straight line and don't drop your hips.
Move your right knee to your right elbow, keeping your whole body tight and in one straight line. Extend your right leg, plant it back on the floor and begin with your left leg. That's one rep. Do 10-15 reps.
