hello all

ok, no doubt this topic has been raised a thousand times before, but could'nt find it anywhere so will ask again if you don't mind :)

been working out at home with dumbbells, and doing push ups (getting pretty good considering the weight i need to actually push up!)
but beginning to notice my right arm looking slightly bigger than my left, especially my triceps

i try my hardest to do exactly the same with both arms, have a big mirror and watch as best i can to ensure both arms are doing the same thing,
however my right arm always feels its had better workout, and its beginning to show i think,
the only thing i can think is that when i was about 9 or 10 i broke my left wrist (both bones in my arm just above the wrist) and previously had not noticed but i can rotate my right arm more than my left slightly, but not to the point where i cant do similar bicep curls etc

is there a solution, i'e add an extra couple of lbs to my left dumbbell or do an extra rep or two with it?

beginning to be really conscious of it :(

thanks
