NordicTrack ellipticals are exercise machines that provide a low-impact cardio workout. These machines simulate the movements the body makes when walking, climbing stairs or running with less impact on the joints.
NordicTrack sells three types of elliptical machines as of August 2014: rear drive, front drive and mid-mech. The rear drive ellipticals are designed for users without a lot of space at home to store workout equipment; they have the smallest footprint and can be folded prior to storing. Front drive ellipticals from NordicTrack allow the user to take longer strides than rear drive ellipticals but are still relatively small. Mid-mech ellipticals are built to withstand a similar level of use that equipment at a gym would have, but they are still small enough to fit in a home.
