It helps a lot to understand where a movement is coming from. With embellishments, many times, the lift of the leg needs to come from the hip.

When a foot beats over and then escapes, it most often is also something that happens as a logical result of the movement of the hip, rather than as something the follower does purposely.

It surprises people how easy it is for us to tell the difference, but there is a huge difference in how natural or unnatural the movement looks.

It also surprises people how hard it is (for many) to learn to just let the embellishment flow rather than doing it.

As a case study, if you were to tap your toe on the ground or strike your heel, you can ask what muscles are engaged and which ones are the most important. We would say the low back, the butt and the upper thigh. Yet, many people, when they exercise this type of movement (or a front boleo) make it about the muscles around their knee and their ankle rather than about the muscles around their hip and thigh. When it is about these wrong things, then the movement becomes stiff and stilted.

As always, it's about the core.
