HOW: Start in a tall plank position. Then, push the ground away from you forwards/upwards which will cause your hips to rise up in the air. For those familiar with yoga, it is like a down dog position. The key is that your shoulders are doing the work!
FEEL: You should feel all the muscles in your shoulder working, especially in your shoulder blades under your arm-pit.
COMPENSATION: Do not push back simply by moving your hips backwards. Actively drive your hands into the ground and use your shoulders to perform the movement.
