I like pull-ups, easily my favorite exercise and I do a lot of them whenever I get the chance. I'm quite familiar with form, do them very strict (elbow lock-out, chin way over bar etc) and vary my grip often. Still, I'd like to add some more peak power to the movement and I'm not sure how. My eventual goal is to progress to a muscle-up, but the bar in my apartment is too close to the ceiling for me to practice this. :)
I guess learning to do a kipping pull-up would be a good idea, but as long as I remember I've been focusing on maintaining absolute control and tension, and a kipping pull-up is completely opposite all that. If kipping pull-ups are the answer, I'd appreciate a link to some good resources on learning to do them.
While my goal is more speed-strength in general, I'd be even happier if the suggestions have carry-over to muscle-ups. Currently, I can do about 10-12 pulls without much problem. I tend to train by "greasing the groove" and doing sets of 4-6, but I also travel a lot and don't have a bar everywhere, so this isn't daily or anything. I'm more interested in exercise suggestions than full programs.
Also, I rock-climb, so any carry-over is welcome (but I am looking for power outside the context of rock-climbing, too).
