Misslegs are funny. For people who don't know what it is: http://www.club540.com/trick/missleg
You just land on one of your legs and then throw everything to your back, extend other hip, extend pecs, extend abs, ramming your foot into the ground so you bounce back up. I tend to transition into some kind of swingthrough by relaxing my non standing hip not sure if that's necessary. Definitely no classic missleg. Just shove your foot really hard into the ground so you bounce back up. Then some extend glutes work and shoulder stuff and you get a little spin out of it.
