how do you protect your face doing barrel/nohand windmills?
also do you pop mostly with your back, or with your shoulder?

With your shoulder. On barrelmills just tuck your head in a little bit and keep your head stiff just let the momentum bring your head down on the floor, once your head is on the floor let it roll (you should be on the upper part of your forehead), remember to keep it stiff and use your arms to protect your face and get high on the mills.
