[Lightweight gym mat that does not slip with excellent grip] The TRNR gym mat is eco-friendly, 6mm thick and reversible. It provides optimal grip and comfort for any workout in the gym. Natural rubber mats usually become heavier as they thicken, but we have achieved weight reduction by incorporating lightweight and non-toxic TPE (thermoplastic elastomer) foam into natural rubber. Natural rubber provides anti-slip effect during training, providing good support and stability. It provides optimal joint cushioning for wrists, elbows, back, hips, knees and ankles. In addition, the closed-cell structure prevents dirt and can be easily wiped off. This mat is suitable for hardwood, vinyl, tile, polished concrete, carpet and any floor surface. It doesn't slip even during the most intense workouts, so you can move with confidence.
