Thread: Left Bicep not growing

Do the same reps and sets with each arm.....if you can curl a DB for 10 reps with your right arm and only 7 with the left...make sure you only do 7 reps for each side.

i have the same problem, my left bicep was smaller but same in strength, back work got rid of it, dont ask me why though!

This was my same exact problem awhile ago, I can do the same weight on each arm and everything. Right bicep is bigger, left is smaller.

2 sets alternating curls

2 sets preacher curls with ez bar - dont do these. They isolate the inner bicep head, especially with a stronger right bicep, youll b pulling more. Inturn this will make your right bicep have more of a peak look to it.

2 sets hammer curls

i put comment sin my quote

I never had this problem although my left arm (I'm right handed) does seem to 'shape up' better than my right though there is no size difference. That's just genetics I suppose.

I have that problem to. My right everything is bigger (no wise cracks please - but the answer is no). I always start any movements left, so on my last left lift the right is equal. You can do some extra sets with your left arm, doesn't help mine though. I really don't know what! you do about this?. Well maybe a little.

dont add sets.. always ends up leading to overtraining.

do one-arm curls, start with your weaker arm. For every rep you left arm does your right arm should do the same. If it takes 7 reps till failiure on the left arm then the right will do 7 reps also, evne if it could possibly to 9 or 10 reps before hitting failiure. The idea is not to stop progress but dont push the right farther ahead. Correct it now before it gets a big problem. But dont worry forever will your body never be exactley equal. One arm will probably always be stronger than the other.

preachers will do that to ya :P

i hate preacher curls.. ppl say its not really an isolation movement, but i mean come on.. your isolating a single head of the bicep, tell me thats not a reaaal isolation movement.

also forearm strength/symmetry should be corrected too, it can seriously contribute to arm weakness/ symmetry.

When I did extra sets, it was on an off day. I would just pick up a dumbbell, and do a few. Done with reason it won't over-train. But it just does not seem to make a lot of difference.

When we are small, and start favoring one, or the other we probably set the pattern then. It may be more shape than size actually. My right has a better peak, while the left seems to be a little longer.

Thats interesting.
Typically for right handed people the LEFT gets bigger.

The left is used for less and typically end up working harder in balancing free weights etc...

nope im right handed and left arm always needs bringing up to right arm standard!

Chances are that you're the only person who notices. No one has a perfect body and this is quite common. I think my right bicep is bigger than my left, but I don't really care. Like Foreman said, do the same reps with each arm, accommodating your weaker one. If you do extra work with your stronger arm, you'll just widen the gap.
