Eh, depends. My internet sucks so hosting is basically a no-go. Joining others’ servers is a game changer when all you got is potato-quality speed.
VR's great, but you gotta consider internet bandwidth and platform accessibility. Not everyone's got fiber-fast internet for streaming HD sweaty avatars. And if you're targeting global, think about server locations. Otherwise, you're gonna have laggy workouts and bad reviews from half the planet.
Download some more RAM for it, that should fix it 😆 Seriously though, if you can't get it sorted, might be time for an upgrade. Nothing lasts forever unfortunately.
