This exercise is intended to open the chest and widen the collarbones, which will prepare the shoulder girdle for some abdominal strengthening work
To do this exercise you will need a mat. Start by lying on your back with your knees bent and your feet planted in the ground. Your hands will be by your sides with your palms facing the ceiling. Inhale as you begin sliding your arms along the ground as if you are making angel wings in the snow. As your arms are becoming even with your shoulders, exhale to continue the slide. Once you get to your full range of motion then inhale as you start to bring the arms back and then exhale to return to the starting position
Things to think about
It is important to keep the collarbones open during this exercise. As your arms are sliding along the floor be sure to be aware of the shoulder blades keeping them as flat to the floor as possible.
