Artificial turf in gyms is a special flooring material, usually made up of synthetic fibers and filler. It looks and feels similar to a real lawn, but is more durable and easy to maintain. The reason artificial turf is used in gyms is that it provides a smooth surface that reduces the risk of injury to athletes, and can provide better cushioning and support to help athletes better complete their training. In addition, artificial turf can provide better sound absorption, reduce noise and vibration, and provide a better training environment.
