Personally I think training like jay cutler, you got to be on roids and other enhance chemicals just like what he's taking in to expect to get good gains close to him or even just like him or even those guys in flex, muscle mags ect. Ofcourse he is able to lift within those 8-12 reps because of those 8-12 reps he is lifting massive weights compared to normal natural bodybuilder and don't forget these "stars" are able to train almost everyday with the same massive poundages and the same high intensisty due to
substances and chemicals they are taking in. Believe me if you consider wanting to get big and not take steroids you have to lift heavy wieghts, not that it has to do with ego but lifting weights within 8-12 reps and not going heavy won't get you the size you want. Pumps don't mean anything other then lactic acid producing. Naturally you can't get big without getting strong and as well you gotta eat big meals and have good rest and recuperation. Please don't waste your time and expecting to get gains lifting 8-12 reps and not lifting heavy unless your just like these "stars" consuming enormous amounts of chemicals. You won't get injured unless you have good perfect technique and form.
