The Elliptical Cross Trainer is a person-powered exercise machine which delivers cardiovascular benefits through elliptical motion.
The exercise completely avoids the impact stress runners often experience on feet, knees, hips and lower back. Many people cannot tolerate the jarring motion of jogging.
The Elliptical Machine improves cardiovascular fitness. Exercise levels can be of 5 to 15 minutes duration. Experiment with various speeds and different levels of intensity.
