Chauncey's climbing coach, Chris Wall, at the Boulder Rock Club likes training climbers with gymnastics rings. There's a whole exercise regimen built around this idea and you can find it at ringtraining.com.

I ordered a pair and installed them on Sunday in our climbing gym. I installed a beam across the short width of the gym which is about 12 ft off the floor. Then we slung the beam with climbing anchor cords and attached the rings to those with carabiners. It's solid as a rock and even me, "gigantor" dad, can hang upside on the rings and do some of these exercises. What a great workout this is.
