What home workout setup genuinely gets used, not just owned?

I've had my share of purchases that seemed like a great idea and then quietly became very expensive coat racks. I'm curious what equipment — or complete absence of it — has actually made home workouts sustainable for you rather than just aspirational. Whether your answer is a pair of dumbbells, a resistance band, or nothing but your own bodyweight, I'd love to know what's earned its place in your routine.
