Used Life Fitness FlexStrider Discover SI
The Life Fitness Flexstrider Discover SI is one of the most intuitive and intelligent fitness machines on the market today. Unlike other trainers in this class, the FlexStrider enables users to change their stride length on the fly—perhaps to change from walking to jogging to sprinting—while the machine adapts and readjusts to support those movements. The wide tactile pedals or platforms include straps to ensure constant contact between the feet and the pedals. This in turn leads to a less impactful workout in terms of stress to the lower body joints and muscles. The handlebars on the machine, which include the proprietary LifePulse digital heart monitoring sensors, also move forward and backward—with resistance—which gives users the unique opportunity to also work their upper body as they walk or run.
