Unit gyms can choose treadmills and elliptical machines, because these two types of fitness equipment are easy to operate and suitable for most employees. In the choice of manufacturers, we can consider Precor, a high-end fitness equipment brand from the United States. Its quality is firm and durable, and it also provides perfect after-sales service and is equipped with indicator light, which can prompt the treadmill to run normally, need to replace the running belt, restart the system, and need to be repaired if it breaks down, which is convenient for the gym managers in the unit to repair.
