Start on your knees with your hands placed close together (narrower than shoulder-width). Keep your back straight and core engaged. Slowly bend your elbows to lower your chest toward the floor while keeping your elbows close to your body. Once you reach a comfortable depth, push through your palms to extend your elbows and return to the starting position. Maintain control throughout the movement and avoid letting your hips sag.
