Hello Danny Oh,
This is a great question. Fads come and go along with gym members’ interest in cardio machines. The best way to approach this is to find out what your members like to use most of the time and work from there so you have enough equipment to go around at all times of the day. Also, what to place on the first floor, in a room, or in a loft, etc.
You could also rotate equipment availability to keep things fresh for your members.
The greatest, latest thing is not always the most popular and profitable, either.

Sorry, I copied and pasted in the middle of my text on the last one. This particular planner looks really cool, like sketching on graph paper. You can put your machines in and then once you like the layout, shop for your own equipment.
Another way to go is to go to a company that sources several brands of exercise equipment. Like this one. They help you with the basic layout design, and can order various items for you, compare / contrast, etc. to get the best layout for your budget and goals.
