Hello its over a year ago since i left school where i used to be one of the best badminton players at the school but now im at college and dont really play badminton at all, now ive been given a coaching job for badminton and im a bit rusty. i spent around 20 minutes earlier just getting a feel of the shuttle *#*#*#*# and the racket again.Im quite busy lately so i dont know if i will have time to go to a local gym or anything to play badminton. Any idea's how i can keep sharp?
