French Fitness CT70 Manual Curve Treadmill

Unlike motorized treadmills that force you to keep up with a set speed, a manual curved treadmill is entirely self-powered. You control the pace by adjusting your position on the curved deck—moving forward speeds it up, while moving toward the rear slows it down. This creates a more natural running experience that engages more muscle groups.

While the CT70 is built to commercial-grade standards for high-volume use in fitness centers, it is perfectly suitable for home gyms. Its durable aluminum belt construction and lack of electrical requirements make it a reliable, low-maintenance choice for serious runners who want a gym-quality workout at home.

Yes, the curve encourages a mid-foot strike rather than a heel strike, which is generally considered more efficient and less impactful on your joints. By forcing you to drive with your legs to move the belt, it naturally promotes a more upright posture and a quicker cadence compared to running on a flat, motorized surface.

Because it lacks a motor, electrical components, and an incline system, the maintenance requirements are significantly lower than standard treadmills. You will primarily need to keep the aluminum belt clean and periodically inspect the belt tension to ensure smooth operation.

You can certainly walk on the CT70, but it is specifically engineered to reward a running or jogging gait. Walking on a curved treadmill can feel slightly different than on a flat surface, so it may take a few sessions to get used to the mechanics if you are primarily a walker.
