back/bi's proportion....

I have been consistantly working out for 5 years...weigh 235 and have descent proportion. My two down falls are that my rt bi is almost a 1/2inch bigger than my left and my right Lat is slightly bigger than my left. Here is what i do for workouts:

Bi
bb curls 4 sets 6-8
seated curl 4 set 6-8
one arm preacher curl 4 sets 6-8
concentrations........4 set 8-10

Back
Pull downs or pullups 4 sets 8-10
t bar rows 4 sets 6-8
cable rows 4 sets 6-8
one arm db rows 4 set 8-10
extension 4 set 10-15

Any suggestions what so ever would be great. Thanks.

Use dumbells, though I've had the same problem for the ten years I've been lifting--some of it's just genetics and there's nothing you can do about it (my brother seems to have the same right/left dominance issues that I do, so I don't beat myself up about it anymore).

it drives me INSANE! I'll have to try to figure it out. If you ever do let me know and i'll do the same. Thanks bro
