Two other options I didn't mention.

Develop your own training plan and hire a coach to work it over. I have a bunch of clients I do this for. I tweak their original plan and for some of them, I review their journal and plan once every month or every two months. There is no other feedback or coaching interaction.

Or, hire a coach to develop a personal plan for you without the coaching aspect. It's a one-time commitment with the coach, but you get a plan specifically developed for you with your background, goals, limitations taken into consideration.

I think either of these would be preferable to a canned plan or on-line training and the cost is probably pretty comparable.
