Trainers, what’s the most common thing clients overlook when building a home gym for an actual program?

I’m curious about this from the trainer side rather than the equipment enthusiast side.

When clients build a home gym, it’s easy to choose equipment based on what looks versatile or what they personally enjoy using.

But once you actually try to program months of training around that setup, I imagine different gaps start showing up.

Maybe there isn’t a good way to progress certain movements, adjust equipment between exercises, train safely near failure, or make reasonable substitutions.

For trainers who program for clients with home gyms, what’s the thing people most often overlook when buying equipment that only becomes obvious once you try to build a real program around it?
