A Three Turn Is a Transition on One Skate

A transition is usually done on two skates. ICP-certified coach Asha Kirkby coaches a version done on one: the forward three turn, also called a lion or free turn, is a one-legged transition from forwards to backwards on inline skates. Same destination, one skate on the ground, and a move she refines through video coaching of skaters who already have it, not a first lesson.
A transition is usually done on two skates: one turns, the other follows, and for a moment both are on the ground pointing opposite ways. A certified coach also coaches a version done on one.
The forward three turn is a one-legged transition from forwards to backwards. It is also called a lion turn or a free turn; the coach uses all three names for the same move. Same destination as the two-footed transition, one skate on the ground.
It is a move she refines through video coaching of skaters who already have it. Her lesson on it is an analysis of a skater's own footage, correcting a three turn that exists, not building one from nothing. That tells you where it sits: after the transition, not instead of it.
The name comes from the trace the skate leaves. A turn on one skate that enters on one curve and leaves on the other draws a shape like the numeral on the ground. The next page is about what makes that shape smooth, and it is not the skate.
