Warrior Heavy Duty Rubber Floor Mats - 3/8 Inch Thick Interlocking Rubber Tiles (4' x 8' Set, 8 Tiles Total) - 10% Green - Durable Gym Flooring, Home Workout Mats & Garage Floor Protection

Definitely the best that money can buy. I gave 4-stars because customer service is lacking. They forgot my corner pieces, and then didn't believe me when I asked them to send them. Also, if something goes wrong, there is no free return shipping.This flooring has worked out quite well for our garage gym. Very happy with it, sturdy, nice looking, we ordered blue speckled, but got red, however, still looks good. Easy to put together, looks like professional gym flooring. Expensive, but worth the money!It's Heavy, it's Rubber, it's good.Rubber flooring that interlocks when placed next to each other. There were some pieces that required some mechanical motivation or water-based lubricant to assist in coupling. So bring your favorite tool. A 2lb rubber mallet worked for me but to each his own.
