up until recently i was a very skinny guy, except for my upper legs, which were pretty muscular, probably from all the bike riding i did. 8 months of weight training have helped, A LOT, but i still have a ways to go. here's the problem -- i do squats because they're a conerstone compound lift and good for skinny guys to do, right?. the thing is, in my case they're making my upper legs too big for the rest of my body. i'm still a very slim guy overall but i'm starting to have problems fitting on some of my jeans, just on the upper legs part. this is starting to get out of hand, and if it keeps going like this, i'm gonna start looking silly, with huge tree trunk legs below a slender upperbody. should i quit doing squats? i don't want my legs any bigger but do want a bigger back (and chest and shoulders and arms) what do i do? can i address this by changing form? should i do deadlifts instead? help!
