Place the BLACKROLL® vertically on the floor. Come intoa plank position with your right arm just next to the roller. Place your right hand on the BLACKROLL® and your left underneath your left shoulder. You feet stand on the toes hipwidth apart.
Keep your whole body tensioned and in one straight line. Bend your elbows and bring your chest towards the ground. The right elbow is bending far back stretching your right chest. Extend your ellbows again and repeat the exercise for 8-10 reps. Then switch sides. Make sure that you keep your body tight and your elbows close to your trunk.
