Elliptical cross trainers provide a low-impact cardiovascular workout that can be a good choice for various fitness levels. The elliptical combines the movements of a stair stepper and a cross-country ski machine, reports the American College of Sports Medicine. Pedals and arm handles on the elliptical combine to provide a full-body workout.
Parts
Elliptical cross trainers consist of two pedals mounted to a flywheel assembly that allows them to move in a smooth, oval motion. Arm handles are connected to these two pedals. A central mast holds stationary handles and a control console with distance, rotation and resistance readouts. If you have a motorized treadmill, the motor will be located within the flywheel assembly.
Types
Elliptical machines can be manual or motorized. Manual trainers require power from batteries or an AC adapter for the console but not the machine itself. Motorized trainers include controls for speed as well. A motorized trainer should include an auto off function, as well as speed controls on the console. Motorized trainers can be noisier than manual ones and can require 220 volt power outlets, in some cases, reports the American College of Sports Medicine.
Function
When you use an elliptical trainer, your feet remain on the pedals. Move your legs forward or backward in a natural stride to move the pedals on the trainer, working within your natural range of motion. The arm handles will move along with the pedals, whether you use them or opt for the stationary handles.
Features
Typically, more expensive trainers are more feature-rich. Some elliptical trainers include heart rate monitors on these stationary handles. All elliptical trainers allow you to adjust the resistance to intensify your workout, either by a push button or a control-wheel mechanism. Some machines allow you to control the elevation of the pedals for a more intense workout.
Benefits
Workouts on an elliptical trainer have a low perceived exertion level, allowing you to work harder and burn more calories according to WomenFitness.net. Elliptical machines are gentle on the knees and back, making them a good choice if you are at high risk for joint injuries, according to the American College of Sports Medicine. You should check with your physician if you have any special health concerns before beginning elliptical workouts.
