What's up fellas? I was just wondering what is the benefit of doing cable internal/external rotations with a towel place under your arm pit? Like you can see here:

What is the difference between doing it with or without a towel roll?
And is there a place online I can order a pre made towel roll that was made for this purpose. Perhaps maybe from a physical therapy website? Does anyone know any good online physical therapy stores that would sell one of these?
