Under the equipment
Foam tiles protect a floor and your joints, and they are easy to lay and lift. Half an inch is fine under dumbbells and a bench. Go thicker, or put down a rubber mat, where a barbell will be dropped.
Thin PVC mats go under treadmills and bikes to stop them walking and to catch sweat. They protect the floor from scratches but not from impact. Folding gymnastics mats are for tumbling and floor work, not for lifting.
