I received one of these Eclipse Elliptical Machines by winning a contest about 2 years ago. I try to use it for at least 30-45 mins per day 3-4 days per week, because it definitely is a good work out. When I first started using it, I had to work myself up to 15 mins at a time, because my body was not used to it at all, it gradually got easier to do longer time periods on the machine as the 1st week or two progressed. I don't really like going to public gyms, I feel much more comfortable working out in my own home but dont have the room for a full gym setup of course. I focus on doing some pilates/yoga, followed by weights, and then using the elliptical and I've gotten great results. I love it, and recommend anybody try this! =) If you're not too sure about it, test one out at a local gym/recreational center first, but I'm sure you will like it!
