I came up with this one today while doin some clamping. I don't know if any of you guys already do this but I haven't read anything about yet so I figured I'd share. To do this exercise first get clamped and really hard, then fold your hands over themselves kinda like you begging or somethin. Fit your hands around your dick( 1 palm on the top 1 on the bottom) and squeeze the hell out of it. I just started clamping so I only do about 5 of these for 30 secs, but do as many as you want. My palms cover the area between the base and head perfectly but for you big guys you may need to do this twice to cover the whole shaft. Hope I explained it alright. Let me know what you think.
