5.21 EFX® - Features
Crossramp® Technology: With Precor patented adjustable CrossRamp® technology, you can alter the height of the elliptical path your foot travels. Called Variable Stride Geometry™, this allows you to focus on a specific muscle group or all major lower-body muscle groups, so you can work the muscles you want, when you want. The Precor EFX® 5.21 Elliptical Crosstrainer™ features a manually adjustable ramp that the user can easily manipulate to alter the ramp angle from 15 to 20 to 25 degrees.
Handlebars: Fixed, for lower-body focus
Biomechanics: Patented, low-impact EFX® motion is smooth and natural, providing the lowest Rate of Perceived Exertion of any cardio exercise system to make your workouts more comfortable, even though you are working out strenuously. The patented motion allows your heels to remain in contact with foot pedals, reducing muscle and tendon stress.
