The Spirit Fitness SP-3526 Functional Trainer is what happens when durability, versatility, safety, and performance are combined. The frame is built using heavy-gauge steel tubing with a powder-coated finish to ensure solid performance year after year. With full-length steel shrouds in both the front and back of the weight stack, and heavy-gauge metal pulley housing covers, precious moving parts are protected to help reduce the risk of injury and prolong the life of the machine.
