Set new fitness goals and break personal bests with the SF-T7723 Force Fitmill Treadmill by Sunny Health and Fitness. This heavy-duty fitness training device provides everything needed for a maximum intensity workout and improved muscular power. The self-powered treadmill stands at a fixed incline of 13.5% promoting a more fluid running motion. The high-density handrails support multi-grip functioning which encourages a versatile yet challenging cardio session. The slip-resistant rails also mimic sled training which allows you to place your shoulders and push against the tread to develop acceleration strength. Increase up to an incredible 16 levels of magnetic tension for a workout proven to increase your performance during both hilly and flat terrain running courses. Dual flywheel structure work together to create a more stable and smooth response for the user. The weight of both flywheels requires a higher energy demand from the user to get the belt started. This can cause a greater metabolic demand or more calories. This is increased when you increase the resistance levels.

I really love this treadmill. Easy to put together. Best part is I did not have to think about where I should plug it in because it is manual. I get a really great workout from this thing!

E

Easy to assemble and very solid. The belt is quiet when walking or running. The incline facilitates a smooth waking motion, but it also presents a nice challenge. Running seems natural and the landing provides plenty of length for long strides. This is definitely a good buy.

Neal S.

It doesn't require electricity but it is definitely a beast of a machine. It keeps my heart pumping, sweat dripping, and legs burning. Very pleased.

M
Montana

I love this so much. I was worried it would be weird to use but you really can just set your own pace. The incline is high but it doesn't bother you like you'd think it would, very easy to use. I love that I can be pacing around and step on it for 10 seconds if I want. Folds up well and to let loose you just hit a button and it lowers itself. Doesn't take up a lot of room and is minimal so it doesn't make things feel crowded. Would recommend.
