Hey guys, Jim from BeastSkills.com, just reviewing some rings from RingTraining.com. The new EXF Rings are the 3rd version of rings that has been offered by the site. Lots of new innovations - rubberized grip, S-hook system that allows doorway mounting and easier ceiling mounting, as well as measurements on the straps. A great piece of equipment I'd recommend picking up for your workouts - http://tinyurl.com/y9fd6as - We use them at my gym extensively and they work great and last forever.
