Well, I made this video to show some methods for developing the Russian dip and the false grip pull up.
I didn't go into much detail on the false grip pull up, because I didn't think about it at the time. I've talked about it other places here but to recap: Once you're doing the more advanced pull ups for sets of 5-10 reps pretty easily with 2 seconds up and 2 seconds down to deadhang each rep, you've got the strength to start working false grip pull ups. False grip is when your wrist is on top of the bar. If you watch my hands in the video you should be able to figure out how to do that. On the rings, your wrist will be at the bottom of the ring curve. If it's off to either side it will hurt. The goal is to have your nipples level with the bar at the top of the pull up, which should have your forearms nearly or completely parallel with the floor. You may not achieve this right away. If you get your shoulders over the bar at first keep doing that until it is easy for 2 sets of 5-10 reps, just to make sure you let your joints adapt. Then go up further. If you can only get to mid-chest, spend time there until you can do 2 sets of 5-10 reps with no strain, 2 seconds up and 2 seconds down. Keep going higher each time you feel no strain for a few weeks at the target sets and reps. You'll be doing great false grip pull ups before you know it!
Once you've got both the full russian dips and full false grip pull ups down pat, no strain, you'll be able to do a muscle up with no problem quite soon, but probably right out of the box. If not, slowly lower down through most of the transition and then push back up. Slow negatives with an emphasis on feeling the body position can help a lot, but for me all it took was powering right up.
