Wow,
I am really inspired by your story. I am 47 and feeling old. Not riding much yet. But since your doing it, I can't make up any excuse that will hold water.

One ab tip for neck pain. I would stretch my elbows to the sides, so that I knew that I was not lifting with my neck. Also, I had a video by Tony Little. He only did a few exercises, but he spent a lot of time talking about isolating your muscles. I haven't done the Firm, so I can't compare them. Also, I am not trained in this stuff, so I don't know if his exercises were the best to do.
