Congrats!!
I spent years riding a stationary bike and playing console games while riding it. It was a workout at first, but then it got so I could go for 2 hours at a time at about 25 mph and not break a sweat... but still not lose any weight... it sucked!
However I had to do it because my husband had a major hissy fit when I would spend a few hours playing a game... yet he was okay with me spending a few hours exercising
So, it may be great for you at first, but I think the benefits might slow down after a while! Either way, best of luck to you!
