Well, I know what I'm practicing tomorrow. Is that why you guys advocate a flatter loop stroke than a mechanically inclined, TT unskilled guy would imagine?
I'm scared now. That info doesn't sound right either. Do you know any coaches or players over 2000? Better to have them show you a good stroke for shadow practice in the mirror.
Here is a story. This is a guy who is a coach and a friend of mine. He is about 2500. He had some back issues and he asked if he and I could do a trade, me fixing his back and he would give me a table tennis lesson. I said sure. And later he watched me play to see what he would need to work on with me. After a while he called me over and he said: "my back, it's not so good, but it's not as bad as your table tennis!" Hahaha. Then he brought me over to a mirror in a room that didn't have tables. The room was for dance.
He showed me a good stroke for FH and a good stroke for BH. Now, it took him about 5-7 min for me to get each, so, 12-15 min total, before he was satisfied that the shadow stroke I did would help me and not make things worse or different bad.
Once I was okay with each stroke he told me, "now, do shadow practice with a mirror 1,000 strokes each side every day from now till Wednesday." It was Saturday. And Wednesday was when he was going to give me the lesson. I did what he asked. And he told me in the lesson that he could tell I did my homework because things were already a lot better.
Anyway, long story short, get someone who really knows what a good stroke is and make them watch until you have it right with the mirror. And then do shadow strokes with the mirror for a while before you try to bring it to the table. A few thousand on each side will really do wonders. That doesn't take that long to do.
