Elliptical machines offer an alternative cardiovascular workout to treadmills. The elliptical machine is so named because of its innovative leg motion. Unlike the pounding motion of running, the oval movement of elliptical pedals makes for a smooth, low-impact workout. The performance of your elliptical depends on several factors including its design and how well you maintain it.
Function
Elliptical machines were designed to provide the user with a low-impact cardio workout. An engineer from Precor created the first elliptical to help his daughter continue training after she suffered a heel injury. She could no longer run due to the pain in her foot, so he designed a machine that offered a low-impact alternative to running.
Front- or Rear-Drive
How an elliptical machine performs is partially determined by the location of the flywheel. The flywheel is located in the back on a rear-drive elliptical and in the front on a front-drive elliptical. Rear-drive elliptical machines were the first on the market. They are generally more expensive and provide the user with a smoother, more natural motion. Front-drive elliptical machines have a flatter foot motion. This design can feel more cramped and uncomfortable. Articulating foot pads that turn inward with the natural motion of your foot are recommended when using a front-drive elliptical to minimize the awkward feel of the machine.
Stride Length
Stride length is an important factor in the overall performance of an elliptical machine. Stride lengths vary from 16 inches to 21 inches, on average. Short stride lengths, especially 18 inches and under, make the elliptical feel jerky and hesitant. Taller users should use an elliptical with a longer stride length.
Design
Some elliptical machine models are designed with an incline ramp. The pedals have wheel rollers that slide up and down this ramp. Although this design provides a smooth motion, it may affect the performance of your elliptical if you don't keep the ramp clean. Over time, dust and dirt, from the air and the shoes of users, collect on the ramp. The wheels have to roll over the debris, resulting in a bumpy, jerky motion.
Maintenance
The overall performance of your elliptical machine will depend on how well you maintain it. Wipe the pedals, wheels and the incline ramp regularly. Depending on the design of your machine, you may also need to lubricate some moving parts to keep your machine running smoothly.
