I don't know how big the gym your company is going to build, what age group the gym is facing, and what the ratio of men to women is. This has a lot to do with the equipment configuration of the gym. Now I'll give you a gym with an average of 300 square meters for men and women in a worker's unit as an example.
Treadmill -5 sets
Elliptical machine -3 sets
Magnetically controlled vehicles -3 sets
Single station multifunctional trainer -2 sets
Dumbbell rack-1 set (2.5-25 fold)
Platform press-1 set
Adjustable supine board-1.
Smith training rack-1
Suspended ceiling sandbag-1
