Start on your hands and toes. Gently lengthen and align your body through your heels to the top of your head. Push your chest slightly away from the floor.
Shift the weight onto one arm and touch your shoulder with the other hand. Keep your pelvis and upper back level.
Through the supporting hand, push your body away from the floor. While keeping your arm straight, slowly allow your shoulder blade to glide towards your spine and lower your chest, then push up again.
