OK, I have a dilemma so I'm looking for advice. I am so not a health club/gym person, I have wasted so much money on memberships I never used. I've got tons of dvd's, pilates, tony banks or whatever he's called, I've got something called "flowin", where you slide all over the place, basically I've spent tons of money on exercise crap and obviously I've used none of it. And actually about a year and a half ago I got this rowing machine, which unfortunately caused me to have a disc sequestration which I've been suffering with since. I've been thru physical therapy, drug therapy, etc. Now, I know that I will never use any sort of mechanical thing but what is your opinion about a treadmill? I'm thinking that it's the best thing I can buy, any ideas??
