The fitness equipment in the community you refer to is probably outdoor fitness equipment, which is generally unprofessional and relatively suitable for moving joints and simple aerobic exercise. Because indoor fitness equipment can't be placed outdoors in the wind, rain, sun and rain, there are some outdoor fitness equipment that imitate the related functions of indoor fitness equipment.

There are also some simple fitness equipment bought in the community, which is far from the equipment in the gym in terms of professionalism. The equipment used in gymnasiums generally requires commercial equipment (which can run for eight hours continuously), so a gym often has tens of thousands of treadmills, while ordinary treadmills are only used for home use or in a community. Therefore, the equipment used in the gym is mainly able to ensure continuous use by many people, with strong functionality and professional requirements for safety, performance and function.
