Working out is already enough of a challenge without having to do it on a hard, cold floor. With the 24 Square Foot Interlocking Eva Foam Exercise Tiles from BalanceFrom Fitness, you get a large area of thick padding so you can complete your set of crunches without unnecessary pain.Made from high-density Eva foam, this 1-inch thick floor mat comfortably cushions your spine, hips, knees, and elbows on hard floors. The double-sided non-stick surfaces have excellent slip resistance to prevent injury and hold the mat in place. The moisture-wicking technology repels any sweat or spilled liquids that could cause a smelly or stained mat. When the time comes for cleaning, rub down the mat with warm water and soap.
