I've only heard great comments about the Peloton bikes. But I just can't get over the up front cost and long term costs of owning one. It seems crazy. I would love to own one, but I'd have a hard time justifying it. That being said, I don't know if a rowing machine is a great approach either. They are an awesome total-body exercise machine... But I just can't imagine that I would personally stay interested in one for very long. I think I'd get bored with it pretty quickly. That's where the Peloton system really shines. The interaction with trainers and peers, and the varying programs, that would KEEP you interested. And let's face it, interest and motivation is what's going to keep you on it regularly. There's certainly a lot of value in that aspect of the Peloton.
