Bro,just about the only thing you can do is isolate your weak arm/leg and hit it with a couple of exra sets.keep really strict form and concetrate on each rep.
its alway tempting to go heavier on your dominant side ,but this is a big mistake.
Oddly enough my dominant side needs to catch up. From my calve to traps my left side is bigger...even my love handels, So I'm even storing fat more. I've tried an extra couple sets isolating just them but doesn't seem to work.
