#214 / KNEE EXTENSION


The most time-efficient strength training device I have ever used. nHANCE™ training maximizes concentric and eccentric loading yet offers a great and smooth servofeel.

The #214 YoYo™ Knee Extension is the ultimate machine to isolate quadriceps use, as it targets all four heads. Using a somewhat tilted seat design and anatomical lumbar support, the #214 YoYo™ Knee Extension allows for either uni-or bilateral coupled concentric-eccentric actions. It accommodates individuals of all body statures with “easy to adjust” settings for thigh-and lower leg. Range of motion (ROM) is readily set by adjusting strap length to produce partial-or full ROM actions, while avoiding over extension about the knee joint.

Like any other nHANCE™ driven by YoYo device, this tool produces eccentric overload, proprioception, stretch shortening and unique neuromuscular stimulation, unheard of before. This is a most effective knee rehab machine acknowledged by sports medicine professionals. But it is an equally effective machine to build quadriceps muscle size.

Thus, this is a most safe tool to employ in any stage of rehabilitation and return to play programs. Exhaustive research* using the #214 YoYo™ Knee Extension has shown great success in treatment of patients recovering from ACL injury and surgery. It is equally appreciated as a method to combat “sarcopenia” in the elderly, as well as muscle atrophy in “want-to-be” astronauts.
