syedee CT01 Black Curved Manual Treadmills sku-13872518918

The syedee CT01 is a Black, user-powered curved treadmill in the Treadmills category (SKU sku-13872518918; UPC 607609285236). Its belt moves as you run, so speed follows your stride without fixed speed settings or electricity.

The maker states that its curved surface engages the glutes and core, raises heart rate and oxygen intake, and burns 35% to 40% more calories over the same distance than a traditional motorized treadmill. The curve encourages forefoot running, which the maker says reduces knee, joint and lower-back impact and the risk of injury.

A flexible, shock-absorbing belt also reduces impact, particularly for longer runs or users with higher body weight. Stride-controlled speed supports interval training, including HIIT. Because it has no motor, it needs no outlet, uses no electricity and avoids motor overheating and fire hazards; the maker also describes easier maintenance and a longer lifespan.

The monitor shows time, distance, speed and calories burned. A holder accommodates a phone or tablet. The treadmill weighs 146 pounds and has transport wheels and a handle for moving it.
