I have been spinning for a few months approximately 3 times a week. I was wondering if I increased my spinning frequency to over 3 times a week if I would receive any additional benefits (staying in shape, burning calories, etc). I know there comes a point where the muscles get used to the movements and was concerned that there wouldn't be any additional advantage to the extra spinning days. I also take a step class once a week and weight train 2 times a week. Thanks much.
