I can no longer do jumping jacks on a hard surface and running can be painful. So last year I swam and biked. But this year I wanted to add to the routine. I shopped around and bought the bellicon. My wife was not pleased at the price but now she loves it too. I can exercise right next to her and the process is virtually silent. When you add in the time and expense of driving to a gym, it is obvious the thing pays for itself.
