Folks, the poster said she can't do squats because of a bad knee. Until we know how bad the knee is, we can't tell her what exercises to do specifically. Also, squats as I said don't make the butt smaller, they make it more muscular somewhat, but they really more affect the part of body doing the work, which are the thighs and calves. When you do a squat, you're working the buttocks some, but the power to do them comes from the more powerful muscles beneath it.
