I was training for a marathon in the Spring of 2009 when I became ill with a very rare disease called CIDP (wikipedia has a good over view) I went from running to using a walker in less than 2 weeks. The gazelle was a big part of the many comebacks I've made thus far. You see, I used a gazelle for years before I became ill. Because my sense of ballance was so keen from the gazelle, the times that I use a walker, I can still use the gazelle with no hands. I've been crippled several times with this odd disease and have made a comeback every time. It's the best rehab machine on the market and I can sure show you how. My wore out gazelle sits in the middle of my living room. Oh, and by the way, the Lexington Herald Leader is doing a story on me and my comeback in their health and wellness section. The story will run on 9/05/12. The reporter saw the gazelle sitting in the living room and I'm hoping she mentions it in the story. Thanks for everything and remember, I believe it is the finest rehabilitation machine on the market, bar none. I have a gym membership at Asbury University, yet, I work out as much on the gazelle as I do the gym as a whole. You'll begin to truly understand my story if you google CIDP up. Thanks again, John B
