California Fitness SlatMill HIIT Treadmill. Serious power. Smarter training. No limits.
SlatMill Overview
- Slat Belt Technology — Less Impact. More Performance. Forget conventional treadmill belts. California Fitness slat belt technology features individual shock-absorbing slats engineered to reduce impact on joints, muscles, and connective tissue. The result? A smoother, softer, more responsive run. Superior cushioning. Smarter engineering. No ordinary treadmill comes close.
- More Durability - Many of the features that make the SlatMill more comfortable also make it more durable, reducing the need for maintenance and/or replacement parts. Unlike conventional treadmills with a conveyor-belt running surface, the SlatMill features an extremely tough running surface made of heavily engineered rubber. This allows our running surface to last for thousands of miles, several times longer than the belt of an average treadmill.
- Low Maintenance - Each treadmill is designed to create significantly less friction and wear, so the belt never needs tracking adjustments, waxing, or deck flipping, since there is no deck to flip.
- Less Electricity - In addition to less wear and tear on its components, the SlatMill's unique design is also more efficient, requiring about 50% less electricity to operate compared to a normal treadmill. The combination of maintenance and electrical savings results in a lower total cost of ownership with less downtime than a conventional treadmill.

Three Training Modes. Unlimited Potential.
- Motorized Running: Dial in your pace from .6 - 14 mph (1 - 22 km/h) for everything from steady-state cardio to high-intensity intervals.
- Free Run: Ditch the motor and run under your own power for a natural, responsive, user-controlled workout.
- Sled Mode: Drive the belt yourself to build explosive power, strength, and muscular endurance with sled-inspired training.
