Ubin Lantai Karet

These went down in my garage gym in about ten minutes and barely budged under my squat rack. The thickness actually absorbs the drop when I set down dumbbells, so my concrete floor isn't taking the beating anymore.

Wasn't sure 4 tiles would be enough for my rack area but they lock together tight with no gaps. Deadlifts and kettlebell swings feel way more solid now, and my downstairs neighbors stopped complaining.

Dropped a 45 lb plate on these and the tile barely dented. The four tiles snapped together tight enough that my rack doesn't wobble anymore. Way better than the flimsy foam mats I had before.
