Tighty Whities

I'm trying to add some muscle mass to my otherwise slim and lean frame. So I'm eating basically whatever I want along with omitting cardio from my routine. In addition, I'm rotating a heavy leg workout into my schedule at least twice a week. As a result, my jeans are fitting more snug. Besides that, my undergarments are riding higher than I like. So, I guess I can't have my cake and eat it too.
