Unfortunately, with the arts, skill only comes with time. There is no speed up process; it all accumulates through time. There are no short cuts. Think of it like this: you take up the arts as a teen. You do thousands of reps through the years, and yeah, know the techniques, forms, etc. Then you watch or feel your instructor, assuming they've been a practitioner for years. Is it the same? Knowledge wise, in terms of execution, and arrangement, sure. In terms of substance- no. A young person might not be able to lock up a large adult. An older artist, throws all very easily. Why? The techniques are the same. The movements for all are the same. It's just a level of skill accumualted through the years. Maybe it is chi, ki, or whatever. It's definitely something.
