Guys I'm having trouble developing lower quad. Vastus medialis(sp?) to be specific. The staple of my leg workout is the squat of course. I know extensions hit the lower quad but I feel with ext is latic acid buildup...that's the way it seems any way. Do you guys sqaut and leg press in the same workout? How many of you guys sissy squat? Or front squat? Just trying to see what you guys would do...
