I know I should be winning a lot more service games than I am doing and I just can't get to the bottom of the problem! I have a problem with the joint in my shoulder and it moves out of positions if I hit big when I'm not warm... Any ideas on what I should do?
If you're 17, from the UK and and about to play ITF's then you're probably training at an iHPC or at least an HPC - which should mean you have some very good coaching resource on your doorstep, try speaking to them rather than asking on here where you'll get replies with absolutely no basis or background (especially seeing as you've not posted a video).
Good luck though
