When everything shut down for Covid, I was glad that we had equipment at home to continue our workouts. The shutdown did force me to acknowledge the weak areas in our home gym. While we had weights and cardio covered, we didn't have a good surface that was conducive to stretching and practicing BJJ techniques when we couldn't go to class. I set out to find a solution that would produce an acceptable surface on a concrete basement floor.I looked at many alternatives and had settled on a huge supplier of MMA mats. The one I honed in on would roll up out of the way when not in use. I started looking for the least expensive place to purchase the mats and landed at Amazon. What I found is that those mats are significantly more expensive for less coverage and that they never go on sale. Since I was shopping Amazon at this point I looked for alternatives and found these. After reading the reviews I ended up ordering 3 mats, which gave us a 10x12 area for about $250 less that what I had been shopping for. These mats seem very sturdy and easily fold out of the way. The velcro appears to be strong enough to hold the mats tightly together while we roll around on them and I don't think we will take them apart often enough to have this wear out. The padding is also thick enough so we do not have any issues using these directly on an epoxy coated concrete floor. The vinyl seems thick enough to be good for the long haul as well.In the end, we will use these several times a week for a little practice but the commercial mats that are more expensive were probably overkill. These mats came with a 2 year warranty so while I don't anticipate any issues with them, I will probably just replace them if something happens to them down the road. These are probably the best value out there in folding gym mats and they are working great for why we bought them so far.
