Personal opinion - most of the time if the question is "Should I do a private lesson or not?" in a vaccuum, the answer is yes. The biggest question is, is it worth it compared to the money that it costs? And is it taking away from regular classes?
It's ultimately beneficial since any questions you have can be asked and answered more thoroughly, and get direct feedback on your technique. Also just time training with someone who knows exactly what's going on. But that feedback isn't necessarily needed at the very beginning (when everyone is learning the same punches/kicks/etc., and ultimately you're not expected to have great form), and if you replace regular classes with them, you're losing out on the opportunity to train with others at/close to your skill level.
As you get more and more advanced, you'll have more questions or things that you'd like to work on, and that's when they have the most use. You know what you want, but not necessarily how to get it, and you can get individual instruction.
Then at some point, you can figure out how to get to your want, and it'll be as beneficial for you to just train at home what you need and self-correct. Then have any larger corrections happen in class. And private instructions are useful if there's a specific thing you need assistance with. An example is that I was struggling with a complex series of drills that take 20-30 minutes just to practice them all once, and they were more advanced than anyone else at my dojo were ready to learn. So I scheduled a private after class to have them reviewed with me, since otherwise we just wouldn't have the time to answer all my questions about it without detracting from everyone else in class.
Zgadzam się w stu procentach – wszystko rozbija się o odpowiedni moment na ścieżce treningowej i świadomość tego, po co właściwie na tę indywidualną lekcję idziemy. Kiedy baza jest już solidnie opanowana, a w głowie pojawiają się konkretne braki do załatania, godzina sam na sam z trenerem daje potężnego kopa progresowego, na który na zwykłych zajęciach grupowych po prostu nie ma przestrzeni. Z kolei po intensywnym bloku treningowym i wyciśnięciu siódmych potów na macie warto zadbać o całkowity reset głowy – w wolny wieczór fajną opcją na niezobowiązujący relaks jest sprawdzić, gdzie wpada
