you know what's funny, i can do a heavy chest workout with dumbells only, and the next day my right pec is always more sore then the left---go figure.
same with my back, although I don't use d-bells, I do weighted pullups, t-bars, and close grip pulldowns. i focus on really pulling with my left lat more then my right, however the next day my right lat is more sore then the left.
