Hey Jogesh, I would say from what I have seen you are doing all the right things, he is putting in the time and effort and also doing fitness drills which you sent us. The next stage for his improvement is to keep improving and work on what he is doing but also look at the serve and return areas of the game, these are the areas that will make the most difference in match play and his results. Of course winning and losing at this stage isn’t everything but still a good way to measure how he is doing.
Maybe send us in a couple of short match clips and we can analyse them again and see where we feel he needs to work on his game and the parts he needs to improve.
Thanks Dan 🙂
