Both monthly cards for fitness are opened together. Because fitness cards are divided into time cards and frequency cards, you must go to the gym within the specified time or times. Gym refers to a place for fitness, rehabilitation and exercise activities. Generally speaking, there are complete facilities, comprehensive fitness and entertainment programs, professional coaches to guide and a good fitness atmosphere. It can be used by many people to cycle or selectively practice on a musical instrument at the same time. This kind of fitness equipment has large volume and complete functions, and is suitable for fitness centers, rehabilitation centers, institutions or school gyms. It should be noted that, for example, the multi-function treadmill is a kind of whole-body fitness equipment, but it only adds the functions of rowing, pedaling, push-ups, waist turning, massage and so on to the single-function treadmill, so it is not very large and suitable for home gyms.
