I was wondering what other ways you can build quads. been having lots of pain on my knees and barley do 45 degree squats, hack squats and leg press, I still put allot of weight just so I can feel something but I am afraid I hit bottom with this method. the funny thing is when I ride my bicycle (and I ride it hard) no pain on the knees but the next day my quads are sore as hell, great feeling knowing I hit those muscle good enough to get sore.
my question is can bicycling help build quads? not looking for Mr. O quads size here, just enough to match my upper body. in other words I don't want to have puny legs with large upper body. I've seen some pro cyclists and their legs are insane! also read some women complaining about legs getting too big from cycling! what is your take on this?
