Hey Kevin, it’s always tricky to know exactly why these things do happen. The thing with table tennis is that it’s such fine margins between playing badly and playing well, it’s definitely a problem that everyone has for sure. If it’s just one week to the next I wouldn’t say it’s a problem with the rubber wearing out as this will happen gradually over time. We all just have bad days unfortunately, the bet players just train a lot and focus on weaknesses so they have less and less of these bad days. You just have to try to also not let these days get you down and try to focus on the areas that the most mistakes are happening so you can learn from them and improve.
Sometimes in table tennis it can be hard to pinpoint exactly why one day you felt good and another day you felt terrible, but I think it’s about not being to hard on yourself, trying to do some fun drills if you have a few days like this in a row to just to keep enjoying it. I’m sure you will be back to playing well very soon!
Tom 🙂
