Generally, all projects are open and receive money at one time. Why is there an item collection? Nanning's Beyond Fitness and Wuxiang Fitness are all annual fees. I think a monthly subscription can attract more people.

To open a gym, you should prepare some combined equipment, such as barbells, dumbbells, treadmills, mirrors, spinning bikes, dressing rooms, etc. If it is very small and can accommodate 50 people at a time, I estimate that 50W should be enough.

Look at the equipment in those fitness books and estimate it.
