Building a cardio corner on our survival server — anyone else into home gym props?

Running a small survival map with a few friends on CraftersLand, and I've been thinking about adding a cardio corner to our community base. The idea is mostly decorative: a couple of treadmill-style props in a glass-walled room, maybe some item frames for that gym look. My concern is redstone — I'd like the belts to animate or at least have a pressure plate trigger lights when someone steps on, but I'm not sure if that's worth the lag on a shared server. We're on a fairly busy world, so I don't want to tank the tick rate for everyone else. I also can't decide whether to build it above ground near spawn or underground so it doesn't clash with the spawn architecture. Anyone here built something similar, and did the moving parts cause issues? Also curious how you handled the flooring so it reads as a gym rather than just another room.
