Whats the best way to incorporate some kind of clamping into my sessions? Right now I am doing the newbie routine. I want to add some girth and wondering if there is a way to clamp with just my hands. Im about 4.6” girth, and almost 7.5” long, so would definitly like to add more girth. Give me some ideas I could do along with my newbie routine where I would not need any type of “equipment”.
