In January of this year, after several years of not riding my bikes, I decided that sitting around and gaining weight was not what I wanted to do. I used to ride a lot with both of my sons but since they have grown up and moved I didn't have anyone to ride with so I just sorta stopped riding. I've finally just said the heck with it and started riding again, by myself. Anyway, I have a stationary bike that I have been riding since January to get into shape and have toyed around with the idea of getting a trainer instead of using the stationary bike. I've been riding the stationary bike a minimum of 3 days a week for 60-80 miles and often more. I live in upstate NY and so far this year, have been pretty limited as to when I can get out either on my road bike or mountain bike because of the weather. I've noticed that when I go from the stationary bike to the road/mtb that it is a completely different type of ride. My question is, would I be better off buying a trainer and putting one of my bikes on it or continue just using the stationary bike for indoor workouts? Which would be more beneficial?
