I had the exact same concern before opening my studio. One thing that really helped was using a professional 3D planning service—it lets you experiment with equipment placement without spending a dime on mistakes. I found www.genense.com/services/3d-gym-design/ particularly useful because it provides realistic layouts and even lets you visualize traffic flow and spacing. It helped me see potential bottlenecks and adjust the design so everything fits comfortably. Honestly, seeing a virtual version of your gym before you buy equipment or paint walls makes a huge difference.
