This is a good page beastskills I can do the 1 arm push up elbow in my problem though to much pushing not enough pulling exercises for chinnies would probably need 2 pulling exercises to get my chinnies up. The muscle up looks solid just a different grip on the bar .My upper body was always the strongest though in the infantry always the last man out the plank .

Trick to the muscle up (on a bar) is explosiveness. When you transition from a pull up to a dip there is a slight adjustment on grip. Personally I use a normal grip, not a false grip, on the muscle up. The way to do it is to slightly propel your feet forward as you feel the point where you begin to swing back, pull yourself up with maximum force. Aim to get the bar to your nipples or lower. As you reach that point it is vital you bring your legs up and pitch your upper body over the bar otherwise you will automatically descend. Once stable in that position you can extend your forearm in to a dip. On descent, use the momentum at the bottom to propel yourself for a second muscle up, your body will be like a spring. The muscle up is not strict but it is far more technical than a cross fit kip muscle up.
Using resistance bands to help get muscle memory in training muscle up and other cali moves is helpful. I'm using a resistance band to help with one arm pull ups.
I recently got rings and getting used to them. Its like learning to walk again.
