'FITNESS REALITY' Real People. Real Results. The Fitness Reality E3000 is perfect for apartments or tight areas, where space saving is a priority. Instead of two exercise machines, you only need the E3000. It will provide a low impact upper and lower body workout using a natural elliptical motion to eliminate any stress on joints and ankles. Then, if you want to switch your workout to an exercise bike, a comfortable large adjustable seat makes the transition very simple. The combination of an elliptical and exercise bike workout will work more and different muscle groups than a single fitness machine.
