Hi due to a knee injury I am currenly not training legs. I have started doing deads again and my ass and upper thighs are growing so fast, that I struggle to fit in my jeans. I have put on about 14lbs in 4 months but worried that most is going to my ass and thighs. Seeing gains in other places too. Not on a cyle yet just creatine. Is this a result of deadlifts?
