A muscle imbalance in the form of shape is geneticA muscle imbalance in the form of strength is also geneticWork one side more than the other and it will more often than not reduce the size of the muscle.Now, measuring the strength of an isolated muscle in near impossible, if you are unable to measure you cannot produce clear results of improved strength gains of that muscle.Make sense?Do both....win / win.But be careful if you have a lat imbalance. Working the weaker side first is a bad idea according to some.
