Our Square Gym Mats are made out of high quality, shock absorbing rubber, and are designed to protect your floors from any type of free-weight lifting, powerlifting, and various other gym workouts. They are also made to provide comfortability and ease while performing lighter workouts such as pushups, sit-ups, and squats. With our rubber floor mats, you will absorb the shock from any dropped weights or pressure and prevent damage to the flooring underneath. You can use them both indoors and outdoors, with the durability to last and provide the protection and support you need.
