There are several keys areas that define a well designed treadmill. All Spirit Fitness models offer comfortable belts and cushioning systems, convenient storage and adjustments, generous features and programs, and eye catching aesthetics. Select the design elements you desire to create a product that will retain its value for years to come. The XT385 has the same options as the XT185 and 285 plus two User programs and up to 15% elevation capability. This model is very appealing to someone that is a walker, at a transitional stage from walking to running, or a mid level runner. This model features a bright blue backlit LCD console, Quick Speed and Incline keys, wireless heart rate (telemetric chest strap included), remote Speed and Incline controls, and an anatomical figure that specifies which muscles are minimally and maximally activated.
