Whats a normal progression of strength for someone who has only been traning 8-9 months and mainly for hypertrophy? iv'e noticed that iv'e gone up well in terms of load for the bench,squat, etc but in terms of bicep isolation exercises such as Hammer Curls my RM has only gone up 15.lbs while my working weight for sets has only gone up by about 7-8lbs on each arm.
It sounds like your pretty much right on track. Even training "just for hypertrophy", if you're brand new to weight training, your strength will increase. Those smaller movements like curls and whatnot won't be going up as much as the bigger moves because...they're smaller moves. Unless you're entering a hammer curl contest, it's no big deal. As long as you're getting stronger and bigger, keep doing what you're doing.
I could spew reams on this topic(or any topic... with plenty of blank pages) but one very well liked by many T-member is the pull-up. The squat should do you; it may not target the biceps but the hormonal response should make a difference.
Also, eating will do wonders. Go up to a larger beer. Start buying kegs and curling that up to your face and then hold at peak contractiong while you chug it.
I really don't buy this shit about squatting making you stronger in the bicep curl. I agree that squatting will help you add more total body mass, which may indirectly help build your biceps, but if you want big biceps, you better do exercises that involve the biceps, such as curls or supinated pulling movements.
Show me a pro bodybuilder that doesn't do curls...
If you do curls properly you'll notice and increase in weight.. Just lean forward when you have the bar in your hand and then when you flex your bicep just throw your body back and "help" the weight up.. but you HAVE to hear your back cracking hard...
You should be able to lift an additional 40 pounds like this..
I am starting to add direct arm work back into my program. Haven't done a whole lot of it in the past few months and it is really catching up to me, my arms are crapping out long before the rest of my body now, oh well, live and learn.
