French Fitness CT100

The curved deck forces you to strike the ground with your mid-foot rather than your heel, which encourages a more natural running gait. Because it is manual, you are responsible for driving the belt, which engages your glutes and hamstrings more actively than a treadmill that pulls your feet along.

No, the French Fitness CT100 is entirely user-powered. The belt moves only when you move, meaning there are no motors, power cords, or electrical components to worry about.

Yes, it is specifically designed for HIIT. Because there is no motor to accelerate or decelerate, you can instantly change your speed by adjusting your stride, making it ideal for sprinting and interval work.

The aluminum slats provide a very firm, consistent surface that feels more like running on a track than a traditional cushioned belt. This construction is extremely durable and designed to handle the high-impact forces of sprinting and sled-push style training.

While it is built for performance running and HIIT, you can certainly walk on it. However, because it is manual, you have to actively push the belt to keep it moving, which makes walking on a curved treadmill feel more like a light resistance workout than a passive stroll.

Maintenance is minimal compared to motorized treadmills since there is no motor or incline system to service. You will primarily need to keep the belt clean and periodically check the belt tension and alignment to ensure smooth operation.
