As I've posted before, I'm spinning and on the weights consistently. I recently bought a body fat % scale. The first day with the new scale I was at 190.5 lbs. and 21.5% body fat. Today (a week later) I'm at 192.5 lbs and 20% body fat. I know the weights are having an effect because my biceps are at 14" which represents an increase. My assumption: I'm gaining weight and losing body fat because muscle weighs more than fat. Does this make sense? And, if my goal is to get leaner and lighter for cycling, should I give up the weights and do more cardio? TIA.
