I apologize right away - I'm not an athlete from the word "at all". I've been to work with a coach individually a couple of times. Everything seemed very confusing and intrusive to me. As a result, the desire to study is completely discouraged. I guess I wasn't ready for just such a pitch)))
Well, actually there are simulators. That's where the advantages ended.
The simulators are bad, they're broken, and no one's going to fix them. The prices don't justify what you get for it.
