Never heard of it? You are not alone. Bound is probably the least known transition by name, although it is utilized often. Bounds are a catch-all for unified transitions. Simply put, they are any unified transition with an adjustment step in the middle. This means that there are 3 main types of bound, one emulating a punch, a pop, and a reverse pop, but with an extra step on the ground. It could be said that bounds are the redirects of 2 footed transitions, and mastery of them comes through mastering the unified transitions and the redirect.
