My DH wants to set up a spare bedroom as a home gym with a treadmill and weights.

The room has hardwood flooring which I obviously don't want damaged.

i was thinking of some of these interlocking rubber floor tiles from Home Depot or similar. Would I need to put anjthing down between the tiles and the hardwood? Wondering if a rug pad would add more protection or be overkill or cause the tiles to slip?

anyone have experience with these products?

Something like this is what I had in mind http://m.homedepot.com/p/FANMATS-Titan-Tile-Black-18-in-x-18-in-Rubber-Tile-Flooring-6-Pack-MM7010/202702690
