We love our Progear Air Elliptical and Exercise Bike with heart pulse sensors. This is a great, low impact workout for the morning, afternoon or night. You can get in a quick workout in the morning while watching the news or an evening one watching a favorite movie or show. The machine is quiet and gives a great workout letting you regulate the intensity and/or go at your own pace. I have two daughters and they like to use it occasionally as well. We have been happy with the performance and have had no difficulties with it. Its a great machine to use during rainy weather or winter when you don't have the option of going outside for a run or jog. I like that it works legs, back and stomach, and its fun to use.
