There are definitely many good suggestions here! And like all of the suggestions, there are choices for everyone and that is the key!!

I have used the Spinervals DVD'S since the 90's and have enjoyed them. I will also say that I generally set up a program for myself in addition to Spinervals or whatever else may be going on.

With that said, I also think that having a personal program/coach is also a great idea. It all comes down to how detailed you want to be, whether you are motivated to stay on a plan, or whether you simply need some help in that area. I know LOTS of people who choose both avenues, and as long as you are aware of what is going on, I think you can be successful with either.

Keep that winter training going everyone!
