Guys, let me tell you the whole story.
When i first came in my club and had a few training with my coach, i saw there was an group of an amateurs playing with average experience of 4 to 10+ years, all of them are his students, plus some other players occasionally cames, sometimes national or pro level, but only because coach is asking them. I have asked can i join to them? The coach said - no, you are too weak. I told him, that I’m master of sport, but in different ones. He told me - this is not a boxing, not mixed atrial arts, so my progression would take long time. Several years, maybe even more. I said him, that i would be playing in this group much faster, and will be one of the best in a year. He just kindly smiled on such a quotes from newbie, and repeat - no, you wouldn’t. So for me understandable, why you so sceptical about it.
Most of amateurs from those group training was about: two times a week with coach for an hour, some sparring games, and one tourney at the end of the week. No serve practise at all.
I did 5 times week 3+ hour with coach, practice matches, some time two times a day. And a lot of serving practise (almost every day) and a tourney as a 6th day of my training week. And it’s about for a year. Other than that i did two strength training in a week as well. As i said to my coach - than i should keep my promise.
If to be honest, I played TT when i was really young kid too, friends of my family, was a TT family where all playing this sport. Father and his older son was on a pretty good national level and much older than me, daughter were not so good and about my age, but again with good technique and everything. I played a lot with here when i was a boy. Maybe it takes some part in the question of my progression.
But as i said, coach invited me to a group in month, and after 8 months, i was among best players of it and constantly winning on them. Does it was an easy to do? No, absolutely. Sometimes when i woke up at 6am at Saturday, the day of a tourney, after whole week of a drained trainings, my body and mind telling me - dude, just stay in bed with your wife. But i still getting up, and going to it. Because i have feeling like i should, if i want to prove my own words that was given to a coach.
To summarise it, there is no direct answer to what exactly was the reason of me improving. Maybe my dedication to trainings, maybe playing with technically correct players when i was a boy, maybe my athletic coordination given by other sports that i did for whole life. But the point is, there is always an exception, and hard work plus good fitness is always pays off and helping you to progress. I’m not a troll, or some kind of an idiot. I have respect for all of a members for this forum, and i will upload some games for the reason, of you can be seeing the whole picture. Wish you all have a nice day, my internet TT buddies 🏓💪
