Lu explains how to do a 180 regrab. This is when you end up in a inverted pull up position, or the end of a skin the cat, you then pull, twist, and kick out your legs to turn around and regrab the bar to starting position.

  Must strengthen your backwards pulling which is a movement many people don’t practice. Must separate your legs and propel them to give you that extra boost up. Body alignment is also important. You want to make sure your shoulder is positioned in front of the bar slight further then it would be if you were going for back lever. At the high point you pull and turn. Doing it, earlier will make it much harder. Proceed with caution.
