Definitely a real kick to the jimmies. I can normally do 15-20 pullups at a stretch using a regular pullup bar, but I can barely do a dozen straight with a set of rings. Definitely a great way to help build one's upper body strength, shoulder and rotator cuff strength and range of motion and grip strength. I'd say great fitness training technique for the martial artist, especially the grappler (I intend to take up BJJ when I get back from my present deployment).
