My form on independent exercises is just as good on my left side i can contract it pretty much just as good etc. Im also just as strong and sometimes stronger on my left side but its just not quite as full or wide on that side. I have only 1 bicep on my right arm so im thinking maybe that has something to do with it? Maybe my left side uses more bicep then my right? Im not sure what would you guys do to start working on this?
End of back day do some width isolated exercises just for my left side or what?
