Those who posted had success, and I am excited that @marieb is going to integrate her 5-5-5 with a bike and do her 15 minutes three times a day. Then the second week, I hope she will add more time, as the Mayo plan calls for, but she has to do what's right for her.
It makes me happy that if we can just get started, we can modify the plan to fit each person's need. I think Mayo probably intended that. Some people may not be able to start with 15 minutes; some may do more. But just getting started is the key. If one person feels excited about exercising, then it's worth it. I didn't answer you immediately because I didn't know and waited to see if anyone would post. Now you can read their posts and mine and see what you think. I believe it's a good addition.
