I'm trying to lose weight so I can be a lighter rider. I started riding at 5'10, 175 pounds with really no fat to lose. I've cut back on the mass building type weight training, but I've really hit my legs hard for strength gains this winter. Now I'm 180 pounds, it's gotta be 5 lb of muscle added onto my legs because I know I didn't put it on my upper body. I don't know what else I can do to get some pounds off. My mother tells me that I look like I weigh 160. Does the rider's body weight even matter that much?
