Gym rings are essential for fitness use. You can use the rings for different fitness activities such as cross training, strength training, gymnastics, pull-ups, diving and more. The rings are made of heavy-duty wood. The wooden surface provides a strong grip without the need for additional chalk. Hence, you can perform your desired exercise, training or fitness activity comfortably. Furthermore, the rings have 9-foot adjustable straps that allow you to hang the rings.
