You may not feel the earth move when you use the Powertec WB-MS Multi-System Gym, but its trademark Earthmover construction bright yellow coloring reflects its rugged durability. Not only is the WB-MS Multi-System Gym built to last, it’s built to give you a wide variety of workouts. This three-station home gym is designed for dozens of free weight exercises in leverage form. Lever arms are driven by pillow block bearings, making it one of the sturdiest in the industry. Since this leverage approach doesn’t use any cables or pulleys, the WB-MS Multi-System Gym is virtually maintenance free. A linkage seat system makes for fast and precise seat adjustments. The frame is a solid 3x2.5-inch steel tubing with a 12-gauge wall thickness--that’s one of the highest specs for any gym. The WB-MS Multi-System Gym is not only a great home gym, it’s a Powertec gym and that’s saying a lot.
