ROPEFLEX Progressive Resistance & DSS explained:
ONGOING INNOVATION: The first company to create the attachable endless rope, ROPEFLEX is fueled by curiosity and ingenuity, resulting in ideation and validation. It is always seeking ways to innovate, improve and expand the landscape to enhance the exercise experience.
Ropeflex was the first company to create and perfect the inertia-fee, gearless and belt-free magnetic resistance for the endless rope training machines (also refereed to as infinity rope or relentless rope). With this maintenance free mechanism user can control resistance or tension in the rope by simply changing the speed or intensity of their pull. This eliminated the need for external resistance control levers or knobs.
Constantly moving forward among our newest innovations is the patent-pending Multi-Level Dual Action Technology. This adds a quick-mode-change to existing progressive resistance. By simply changing the pulling direction and reversing the direction of the drums rotation, users can activate either the cardio or strength mode in which the progressive resistance automatically adjusts from five to 300 pounds based on the pull acceleration.
DSS innovation - pull direction changes resistance
Integral to this technology is the one-of-a-kind Dual-Speed-Strength (DSS) drum, which facilitate lighter resistance for cardio and heavier resistance for strength work, providing a smoother pulling experience with virtually silent operation.
