Life Fitness's goal was to build treadmills that people would want to use instead of running outside, even if weather conditions were perfect. No small task to say the least. But their product engineers are runners too, so they welcomed the challenge. In the end, they built the best machines, revolutionary treadmills that are fully-loaded with patented technology and exclusive performance features. Life Fitness treadmills are powerful running, walking, and jogging machines that are the top choice among exercise enthusiasts around the world. From the introductory model to the ultimate home version of their club model, there's nothing like training on a Life Fitness T-Series, F-Series, Club or Platinum Club Series Treadmill.
