Elliptical machines, also known as cross-trainers, provide a low-impact workout that works the legs and arms. These types of exercise machines follow behind the treadmill in popularity, according to Smooth Fitness, an elliptical manufacturer. Elliptical machines come as a rear-drive or front-drive model. The differences between the two will appeal to each user differently based on their exercise needs and budget constraints.
Significance
Typically known as a low-impact exercise machine, rear-drive and front-drive elliptical machines work differently, each providing you a different workout experience.
How They Work
Front-drive elliptical machine pedals operate on rails located on the machine's rear end. Front-drive ellipticals have single or double wheels; double wheels provide more stability.
Rear-drive elliptical machines operate on a floating system -- no rails or tracks -- with bearings that roll freely.
What It Feels Like
Using a front-drive elliptical machine feels similar to using a stair climber. You have to lean forward slightly when using this type of elliptical.
Rear-drive ellipticals closely mimic the motion of walking or running. It keeps you centered on the machine and eliminates back strain.
Cost
Front-drive elliptical machines, typically cheaper, cost less to manufacturer. You will usually find rear-drives on the more expensive elliptical machines. Cost differences between the two can vary as much as several hundred dollars.
Considerations
Some front-drive elliptical machines contain concave wheels that come off their track easier. These types of wheels cause more noise during operation and may require more cleaning and maintenance.
Front-drive ellipticals, because they have tracks, require more cleaning in general. If you don't keep the tracks clean, they can get dirty and cause components to wear down quicker. Since most rear-drive ellipticals use a floating system instead of a track system; the floating system contains fewer components and there are no tracks or wheels to keep clean.
Both types of ellipticals require regular lubrication. You must also tighten the bolts and screws as needed to keep it operating efficiently.
When buying a front-drive elliptical machine, look for articulating pedals. These types of pedals flatten the pedal to allow your feet to stay flat, offering a more comfortable motion.
