Hey Deep, things are gradually getting more enjoyable for sure, hope you are well too! That’s great that you will be playing the grand prix, there will certainly be quite a few of the TableTennisDaily team members there and quite possibly Dan and myself too.
Good idea regarding the fitness routine and it will definitely help your table tennis getting into good shape for sure. Good that you have shaken off the early rustiness already in your training. In terms of preparing for the vent I would say right now you want to focus on movement and speed around the table, doing plenty of regular drills for the next couple of weeks, then you’ll need to up the irregular drills and serve and return aspects, and continue increasing the serve and return drills more and more right up to the event.
These are the most match realistic elements that will help you at the event. Also for sure playing practice matches at the end of your sessions against a variety of players if possible will certainly help before the tournament.
I also definitely recommend the week before the tournament, try to really focus on your strengths in training and your point winning areas of your game. Make sure those are going well and this will help the confidence in your game and tactics going into the tournament!
