TRUE TSX elliptical cross-trainers, built on a commercial platform, combines the durability and performance expected from TRUE. A more compact design to maximize space proves to be a better fit for a home fitness program. The TRUE patented Core Drive™ system provides the most natural movement while keeping the user centered for superior balance, stability and comfort. TSX ellipticals also feature our side step system for safe entry and exit of the machine. Plus, by stepping off onto the patent-pending side steps, the TSX home elliptical machine allows you to work just your upper body, a feature that only TRUE offers.
