Two 106-pound stacks of vinyl-covered weights provide 212 pounds of muscle-sculpting resistance on the Weider Pro 9400. Best of all, the stacks operate separately so two people can work out simultaneously. The Pro 9400 has seven complete stations. The upper-body station focuses on the chest press and military press. The butterfly arms station gives you a complete pectoral workout to add definition. Quads get a balanced workout with the leg press and leg developer stations. Add to all this the high pulley/lat bar, ab developer, and low pulley, and the Weider Pro 9400 gives you a complete workout at half the price of most products providing the same exercises. The Weider Pro 9400 is definitely a great Budget Buy.
