Do your elbows hurt? Do you do lots of pull ups on a bar? Well the Metolius Rock Rings may be your answer. Basically hanging handholds, allowing the arms to rotate through the pullup motion, helping to prevent that dreaded tendonitis in the ole elbows. Plus the pockets isolate the fingers emphasizing the body parts that really need the training anyway, the fingers and forearms!!! We are training for rock climbing anyway right? Metolius Rock Rings are a must for anyone wanting to be a stronger climber. Portable and affordable as well.
