Running is part of just about every sport from basketball, football, track & field, crossfit, triathlon, to gymnastics and tennis and Form is the building block for performance, endurance, and resilience. Form is, and always has been, our Focus. To TRUEFORM those words are not a slick marketing phrase picked up from our competitors along the way it is our raison d'etre - our reason for being. That focus is designed into our Runners through every phase of our engineering design, manufacturing, and testing at our training facility in Connecticut, USA. Under traditional, machine-assisted acceleration, a runner tends to fall forward, perpetually trying to chase the belt, and running more "quad dominant" with less focus on the posterior. Not only does this lead to poor form, but through that an increased likelihood of injury. Even with some other curved non-motorized treadmills, a curve of 6.5 to 8 inches, allows the runner to move faster in an easier fashion since gravity is assisting with the movement downward once the foot plants. All TRUEFORMs have an innovative very gentle curve of 2.5 inches from lowest part of curve to the highest point at the front and rear. With the TRUEFORM.RUNNER, you focus more on what's beneath your feet keeping you in better dynamic balance with less focus on trying to keep up with the belt.
