http://badminton-coach.co.uk/ This is a new but up and coming website with videos and articles to improve ur badminton from an advanced coach who has lots of experience as can be found on this website. There still isn't a lot of articles just yet but each month, more are being added. Keep your eyes on this website
Is this your personal site? Im looking forward to this , particularly a very good passage and video about the CORRECT PRONATION TECHNIQUE!? Lol
No its not my site but I found it and emailed the coach asking him a few questions about badminton fitness and tactics etc and he was very quick to respond and very friendly. Seems like a nice guy with lots of knowledge of the game. Jus want to share his site with every1 else here on BC
