Equipment guide
Flooring is easy to treat as an afterthought, but it's what protects both your actual floor and your equipment from repeated impact, and the right thickness depends heavily on what you're doing on top of it.
Thickness should match your heaviest impact, not your average session: 3/8-inch to 1/2-inch mats are fine for general lifting and machine work, while dropped Olympic lifts, heavy deadlifts, or a rower with a hard footprint call for 3/4-inch or thicker rubber to protect the subfloor underneath.
Interlocking tiles are easier to install and replace piece by piece if one section wears out, while large rolled mats give a more seamless surface with fewer seams to catch a bar or wheel, which matters more for cardio equipment than for a lifting platform.
Subfloor matters as much as the mat itself: concrete slabs generally need less cushioning than floors over a wood subfloor or joists, where more thickness helps absorb impact and reduce noise transfer.

3/8 to 1/2 inch is usually enough for general lifting and machine work. If you're dropping bars from overhead, doing heavy deadlifts, or using a rower on a hard floor, 3/4 inch or thicker protects the subfloor and equipment better.
It's still worth it. Concrete is durable but unforgiving on joints and loud when weight is set down; rubber flooring protects both the concrete and your equipment, and cuts down on noise and vibration.
Interlocking tiles are easier to install yourself and let you replace a single worn section without redoing the whole floor. Rolled mats give a more seamless surface with fewer seams, which is nicer under cardio equipment with wheels or sliding motion.
