Two more thoughts on this, because it's a complicated issue.
1. Why not show your coach the Yodkhunpon shadowboxing session so he knows what page you are on. It could be that you are doing it earnestly, but maybe missing elements of what could be found in the video. It helps to have an educated eye looking on. If you want to gift him a month of Library access for free, we can do that. Just have him sign up and we'll send a refund for that month.
2. In a very different direction, we have a philosophy of gyms and training opportunities what is the logic of the Cupcake Bakery. If a bakery is really great at making cupcakes, and everything that comes out of it is cupcakes...and you don't want to be a cupcake, you want to be something different, it doesn't mean that you can't "go" to that bakery. It just means that you have to look at what the process (the gym, the coach) produces, and know that at a certain point you have to break off, or include other processes...or, you'll become a cupcake. For someone like Sylvie there just is no gym, trainer, promotion, NOTHING that will produce what she wants to become. None. So it is all cupcake bakeries, croissant factories, ice cream cake showrooms, it's all processes that make things other than what she wants to be. So, it takes a careful combination of processes - processes that make other things - to (possibly) create something new, the thing she wants to be. It means, unfortunately, ALL the processes are "wrong" in some way. But taking elements from many of them, changing those processes over time, could combine some of their strengths into a virgin ground territory.
It also takes great patience and perspective for any particular process. It just isn't going to be baby bear. All are going to be mis-fitting.
