I have an old DP Fitness for Life Air Strider. I call it a stand up bicycle, since their is no seat. On it, my feet go around in a pedal motion. For my arms, I hold on to two levers (handles) that go back and forth and enable my arms to make the same motion I would make if I was running. The whole exercise seems equivalent to jogging without the impact that you would get on the ground. I really liked this machine, but it is now worn out. What do they call this kind of exercise equipment today? Where can I get a good deal, possibly factory refurbished? Thanks!
