My name is Amanda and I am a 40 year old single mother. I was given the Treadclimber 3000 as a 40th birthday gift by my mother. When I started working out in April 2008 I weighed 218 lbs. I now weigh 168 lbs and I feel better than I have in years. I was worried that this machine would not work for me, but I am so glad that my mother purchased it for me. I am now wearing clothes I haven't been able to wear in years. I still have to lose 28 lbs to reach my goal weight of 140 lbs. I have no doubt that as long as stay the course with the TC3000 I will reach it before the end of the year.
