Whatever you get, you need some type of program to keep you motivated so you just don't go thru the motions.
Running with this thought from Toyman in my thread about spin bikes, I see this is where my mind needs to be right now. I have a magnetic resistance upright bike and need a program or train of thought to get to where I need to be, just fit with no competitive dream. Starting from scratch I am trying to get consistently fit. I suffer from degenerate disk in my upper back, and RA. Finding it very hard to get started in the morning going to the bike after some form of intake seems to be a good place to start. As Toyman says a program is needed, but there is so much out there. I rode this morning and find right now maybe intervals are best or all I can do. I am open to any trains of thought, but the simpler the better.
