STEPR TREADSLED XL VPR™

The STEPR TREADSLED XL is built around VPR™ technology—a patented air-resistance system that redefines what a curved manual treadmill can do. By combining free running and heavy sled-style resistance in a single platform, the TREADSLED XL delivers effort-driven training that adapts instantly to the athlete. VPR™ is a patented air-resistance system that delivers over 100 virtual levels of load without motors, weight stacks, or electronics. Resistance increases smoothly as output rises, creating a self-regulating training experience where speed and force determine the challenge. This wide, responsive range supports everything from light turnover and aerobic conditioning to sprint intervals, threshold work, and heavy push sessions—all on the same machine, with no adjustments or setup changes required.
