HOW: Starting in a tall plank position with your hands and feet on the ground. Push your arms into the ground and protract your scapula to push your hips into the air in the down dog position. Really drive this motion through your shoulder blades. Next, shift your weight forward and let your hips sag to the ground. Arch your upper back as you assume the up dog position. Then repeat.
FEEL: You should feel all the muscles in your shoulder working, especially in your shoulder blades under your arm-pit during the down dog. During the up dog, you should feel a gentle stretch you’re the front of your hips and your middle back.
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. Do not let your hips touch the ground during the up dog, keep them elevated just slightly.
