| If you think you are disproportionate, first off all people's view of themselves is often more harsh and sometimes even unrealistic as compared to how other people see them, so posting a picture might not be a bad idea. Either way if you did not want to gain much size on your lower body/legs or even lose a little size there if there is some "reserves" there I would do your normal upper body workouts, possibly lower body workouts as well, but I would do low weight high rep and take it easy on the lower body. And also I would run relatively slower at a longer distance as upposed to sprinting. In my experience that might be something that might help you. |
