Touch-N-Go™ Programs - Green means go. All of the green buttons or any programs with a green border around them are a Quick Start button, just push and go.
Vari-Stride™ - A unique elliptical program that varies stride length throughout the workout, allowing users to target multiple muscle groups for maximum training results.
