The Speedfit Treadmill doesn't come with a motor. Instead, you use your body's own gravity to push the belt along, resulting in greater calorie burn. You can walk, jog, and sprint at your leisure with the shock-absorbing belt keeping you comfortable every step of the way.


Is the Speedfit Treadmill best for you?

The Speedfit Treadmill is the original curved running system. In lieu of a motor pushing the belt, you go at whatever pace is most comfortable for you. You can start with a light walk and then gradually build to a sprint without having to adjust any of the settings on the display. It's a revolutionary system that's been imitated by other brands in the years since its release.

You can also take a 10-minute test to determine where you're at health-wise. From there, the system offers you a selection of over 5,000 personal workouts to help you perform your best. The Speedfit Treadmill is a great choice for beginners and experts alike who want a machine that grows with them.

Consider Speedfit Treadmill if...

  • You need to burn more calories. The Speedfit Treadmill uses the force from your own body to move. As a result, you utilize more energy in a shorter span of time. This allows you to burn more calories, so you end up with more productive workout sessions.
  • You want a completely customized experience. This non-motorized treadmill allows you to go at whatever pace you are most comfortable with. As such, there are over 5,000 personal workouts you can choose from. There's always something new and different to try.
  • You like not worrying about the motor. The motor is often the first part to break on many treadmills. Since the Speedfit doesn't come with that, you don't have to worry about needing to buy an expensive replacement.

Avoid Speedfit Treadmill if...

  • You want a more standard treadmill experience. For newcomers, getting used to utilizing your own gravity takes some time. A lot of people prefer the treadmill belt to do most of the work. A treadmill like the NordicTrack Z 1300i may be more your speed.
  • You don't want to spend a lot of money. The Speedfit Treadmill costs quite a lot, sometimes twice as much as other treadmills. If you can't afford to spend thousands of dollars on a piece of exercise equipment, then it may not be right for you.
  • You don't like not having a water bottle present. There are no bottle holders on the Speedfit Treadmill. You're going to have to wait until you can safely come off the treadmill before you can quench your thirst.
