I am considering a roller for winter exercise. It looks like it's a helluva lot more challenging, as well as more fun and engaging, than stationary bikes.

But they also look very tricky, especially for a rickety 50 year old like me. I am looking for educated opinions on this. Should I go the stationary route or do I dare try this at home?
