USEFUL: Gymnastic Rings 101: Why to Use Them, How to Buy Them, and Where to Hang Them. “Skill work on gymnastic rings integrates strength and coordination training in a way that’s much harder to achieve with other equipment, and it gives you a lot of bang for your buck with regards to training time. It’s very common to hear of strong and fit people that exercise with weights and machines all the time, but are humbled and amazed by how difficult it is to perform even the most basic rings exercises. It is intense training that only requires a few movements to equal the impact of a dozen other regular exercises available in the gym.”
