How are rings any different to a pull-up bar?
There are many reasons why gym rings are a better choice over traditional fixed apparatus – Rings are height adjustable, portable and offer the element of free motion which is kinder on the joints than a fixed bar because it allows for more natural paths of motion throughout the exercises. The instability of the rings increases the intensity of the exercise making them more difficult, yet effective than standard methods. The rings are so versatile due to their portability and height-adjustment and there are many exercises that just aren’t possible on a fixed pull-up bar such as push-ups, dips and the iron cross, to mention but a few.
