I'm not a young pup anymore and the situp, pushup, highspeed bike thing is out of the question. That's for younger, in-shape people. I have an irrepairable hernia that would not work with this kind of a workout.
I also need something that I can fold up and put in a very small coat closet when not in use. So, for me anyway. I think what I picked out is probably the best choice.
I've looked over the page you listed, and I still haven't been able to figure out what these things are. I don't see anyplace to sit, etc. I definitely don't want to have to purchase something that's non-portable, causing me to have to also purchase a bike and have this mess all sitting in my living room in front of the TV forever.
For me, there are no commercials.
