I remember someone else selling a back-pumping machine, or am I mistaken? About six months ago I saw some pictures and got a reply. But at that time I was offered the opportunity to buy it with a bathroom scale so that my fitness routine would be optimal. I laughed at the time, but took the scale. But I didn't buy that exerciser. Only now there is an opportunity. Is anyone selling any of their arsenal? I'm planning a year-long post-rehab exercise program and really need some advice on how to organise my classes.
