I'm looking for something to put over a section of my hardwood floor when I do HIIT workouts and then hide away in a closet afterwards. Will the tiles stay in place without being anchored or would I need a non-slip mat underneath? How durable are the puzzle edges in terms of repeated assembly/disassembly?

White the Premium Soft Wood Tiles are very durable and meant to be assembled and disassembled often, we do not suggest these tiles for HIIT workouts. The quick lateral movement of HIIT workouts can pull the tiles apart. We often suggest using one of our rubber mats or Home Wrestling Mats for HIIT workouts.
