I have been reading so much about the bench not being the best exercise for pec development. So I starting doing isolation exercises and tweaks on the bench and incline. I felt more pump in the muscles but the development hadn't come like I had hoped. Well I decided to enter a local bench contest for the hell of it and started hitting bench again this time with a more narrow grip than usual for me.
Well holy cow the pump and density of my pecs has increased dramaticsally. I have been using your double progression model and it has been great. Any reason why the bench is now working so well for me now?
