The Gym Gear gym rings are fully adjustable and designed to be used on any rig or fixed bar. Constructed from hardened PU, the rings offer excellent grip. As the rings aren’t fixed they tend to move naturally, meaning users need to control their core and balance to execute the exercises. The rings allow for safe and effective exercise progressions and can be used by anyone. Ideal for exercises including: pull ups, dips, muscle-ups, straight-arm holds, leg raises and free-shoulder stands. Our Gym Rings are an excellent tool for building dynamic, upper-body strength.
