As I'm fond of saying... Fitness is a journey, not a destination. The bodily changes and improvement of physical abilities you seek are not determined by the equipment you need. So what are you waiting for? Traditional Exercise bikes have been around for some time. They also provide a good cardio workout if properly used, and many come with built in features such as an adjustable platform and computerized workout to help enhance the effects of your exercise routine. There is some jarring and joint stress involved with running, on a treadmill or other surface, so this equipment may not be a good choice for those who want to burn calories and get a good cardio workout with reduced impact to knees and hips. Stepping height can be adjusted to accommodate different body sizes and fitness levels, however, it can be easy to put too much stress on ankles and back when using a stair stepper. Both size and price are in the moderate range. Once you have effectively added physical activity into your lifestyle.
