some guys make up for lack of strenght with more excersizes. I Really am not that strong. So when I work the arms I have to hit them at every angle.Straight bar biscep curls,ez bar curls,hammer curls.single dumbell curls,concentration curls,some times curls with the pully machines,incline curls scott curls all kinds of curls to get my arms to grow and triceps lots of dips eye crushers reverse grip eye crushers,kick back to the side and above the heads lots of tricep rope extentions.
I noticed the same thing i stopped slinging around mad weight and focused on the lifts with my arms in better form. Curls with using on the biceps and no swinging or front delt help. and the biceps grew better with half the weight using a 12-15 rep range vs me slinging shit around 6 reps and swaying.
So I say its true me atleast also I keep the compound lifts heavey deads squats, bench press,power cleans..
But when it comes to arms Only pussy weight with strict form and lots of angles and excersizes in the 12 range makes my arms grow.But I will still go heavey 6 reps range on the straight bar and tricep pulldowns becuase they are not quit as much a isolation excersize as say single handed concentration curls and one arm reverse grip tricep extentions.
everyone as to find out what makes them grow some people have more red fibers then white fibers or vice versa ,some people respond to lighter weights more reps.You cant just work the bodi in the same rep range every day and expect diff results.
I watched eddie robinson at golds gym in clearwater back in 1996 when I just got into weight lifting he was a pro with his pro card already.I watched that fucker real close when all the gym ratts were gone and no one was around that dude was only doing 30 lbs alternating curls and 75 lbs on the ez bar but real slow and isolated leaning up against a awall. but days when the ratts were around he was slinging 225 on the olypmpic bar doing curls prob is he was working almost everything but his biceps .I also rember seeing lee labrada doing 60lb ez bar curls in a joe weider vedio from 1988 that came witha bucket of megga mass 2000. And lee labrada weighst he used were nothing special and he placed 2nd at the olymipia next to lee haney.
I think were some guys forget about is the form if some one is using 60lbs ex curl curl bar isolated with elbows down to the sides to swinging of the back and its pure biceps doing the curl full contraction flexing at the top lowering the weight down for the count of 3 seconds then slwoly lifting again for three seconds your looking at 12 reps taking around 1minute and 30 seconds to finish thats alot of stress for the biceps vs slinging around double the weight for 20-30 seconds.So the guy lifting the lighter weight can make up for it by having a longer hang time meaning the bicpes were under stress 4-5 times longer then the heavy bad form lifts.
shawn ray is another guy that did strict concentration full flexing of the muscle during the lifts and build a awsome quality body he open admitted to not doing abench press over 300lbs more then once or twice in his life.I think you guys would be real surprised that many of these big guys besides the 3 major lifts dont use much weight for the other lifts and use isolation alot.expect people like dorina yates colmane but and the top pros those fucker prob do one 100lb dumbell curls in each arm.but they also pay the price dorians ripped biceps and coleman ripped his also all the pros that lift with freaky weights seem to have pec tears as well.
its all on attitude some guys will lift for health and lift for 25-30 years or their entire lift.Or some guys will lift as heavey as they can untill they rip something so bad they can never lift again.
