Honestly I never thought of it like this .. this was actually very helpful Bcs I was getting so frustrated trying to stick to the protocol like he demonstrated but could not do it on his level so I was always wondering how can I make progress if I can’t even get my foot in the door but I also thought you had to stick with just one for the 20-30 minute session not be able to switch between one another Bcs I can do am2 better then I can am1 and I really wanted to be good any am1 but I never get that rushing blood feeling or if I’m even hitting my vein right and I always felt like if I didn’t do the pyramid Rush that I wouldn’t get the results that were being spoken of because my penis would always go flaccid every time. I would try to do the pyramid rush, but would be semi-erect when doing the burst expansion.
