It’s the first of its kind to combine smooth manual running with real sled-push capability—all powered by patented VPR™ air resistance. Whether you're doing a speed session or a strength circuit, the Treadsled adapts to your effort instantly. One machine. Two powerful modes. Infinite training potential. .video-container { position: relative; width: 100%; padding-bottom: 56.25%; /* 16:9 Aspect Ratio */ border-radius: 16px; box-shadow: 0 4px 16px rgba(0, 0, 0, 0.2); overflow: hidden; } .video-container iframe { position: absolute; top: 0; left: 0; width: 100%; height: 100%; border: 0; border-radius: 16px; } Run or Push—Switch Between Modes Instantly The Treadsled XL is engineered for both sprinting and sled-push training. Flip a switch and shift from free-run mode to resistance-loaded sled drive. There’s no power cord, no motor—just you and the machine. VPR™ adapts to every stride and push, giving you complete control from light jogs to full sled drives. This is indoor conditioning with zero compromises. Dual-mode: Free run or sled push on demand Train speed, acceleration, and raw drive power Ideal for strength circuits, intervals, or rehab No motors or magnets—just dynamic, real resistance Real-Time Adaptive Resistance That Moves With You The Treadsled XL uses STEPR’s patented VPR™ technology to scale resistance in real time. The harder you run or push, the more resistance it delivers. It’s frictionless, fluid, and feels exactly like the resistance you’d face pushing a loaded sled or grinding through a hill sprint. No manual knobs or settings—just effort-driven resistance every time. Over 100 virtual resistance levels via VPR™ Adaptive turbine adjusts instantly to your output Great for sprints, sled pushes, and strength work Designed for all fitness levels and goals Strength Training Meets Sprint Mechanics in One System Whether you're conditioning for sport or just training hard, the Treadsled gives you the tools to load your legs, build your base, and improve your power. In Sled Mode, resistance mimics pushing heavy objects like a car or truck. In Run Mode, inertia feels smooth and natural—ideal for improving cadence, gait, and form without the shock of a motorized belt. Push-style workouts with realistic sled feel Sprint with proper form and consistent load Train horizontal force production and acceleration Shift modes mid-workout without stopping Biomechanically Engineered for a Better Running Experience The curve and deck geometry of the Treadsled are designed to feel natural underfoot, reducing joint stress while improving posture and movement mechanics. Whether you're moving fast or slow, resistance adjusts without throwing off your rhythm. And the anti-rollback system adds extra confidence for high-load pushes. Curved deck supports natural stride and posture Built-in anti-rollback system for safety under load Frictionless running feel even at high speeds Supports full stride and sprint mechanics Train Anywhere—No Power, No Setup Required The Treadsled XL requires no power source, making it perfect for any training space.
