Scratch Stretch

Anterior Deltiod flexibility is sometimes measured in terms of how far an individual can reach behind their back and up the opposite shoulder blade. This is often referred to as a scratch test. To improve flexibility, start by reaching arm behind back and up the opposite shoulder blade as high as you can, then grab a secure object the same height. Next, with lower back arched, abdominals drawn in, and chin up, slowly lower into a squat increasing stretch height. Take care not to overstretch as no stretch should be painful.
