My Left Bicep Smaller Than My Right Bicep ??

[Von Milash]

It happens to everyone, ICB. Whichever side is dominate is doing more work.

You need to do some extra work using just your left arm. Various dumbell curls should do the trick. Another angle to take is doing some dumbell curls with your right arm first to weaken it and then do barbell curls so that your left arm has to pick up the slack for your right.

yep. my right arm is naturally stonger than my left, but i've done so much work on my left with my pulley system that my left is now bigger and stronger than my right. but my right will always be naturally better coordinated so it doesn't need as much strength.
