Manufacturing line is a production line between a single or a few varieties, a large number of inflexible automatic lines and small and medium-sized multi-variety FMS.

A typical multifunctional gym is suitable for weightlifters. It will have a bench press, detachable bench press, handles for leg press, latissimus dorsi, triceps brachii, shoulders and arms, and free weight.

Many multi-functional gyms have aerobic exercise equipment, such as treadmills on stairs and spinning bikes on bicycles.

When setting up a multi-functional gym at home, generally only one person can be used at a time, but sometimes two people can be used, depending on the weight of the machine, the weight of the exerciser and the specific model specifications. Be sure to put it in a cool room without windows or away from windows, because you don't want to exercise in the glare of the sun, and you don't want the sun to discolor the white paint over time.
