Curve treadmill SI-20B

Run Reinvented: the SI-20B Curved Treadmill

The SI-20B Cooper Silver Line curved treadmill introduces a new paradigm in running: entirely motor-free, your own stride powers the belt. This 100 % manual operation increases demands on strength, explosiveness, and the posterior chain while removing mechanical constraints.

With its curved design, the treadmill encourages a more natural posture and dynamic propulsion. This mechanism results in greater muscle activation, self-regulated intensity, and improved metabolic return — ideal for HIIT and interval training.

Built for intensive use with a robust frame, the SI-20B remains relatively compact. It requires no electricity or wiring: no motor and no power cord needed. This lowers maintenance costs and simplifies installation in any facility.
