I'm 16 and I'm a football goalie. What's the best training to become better all round??

Hi Firstly I would suggest buying a random light reactor - its one of those boards with several lights on above below in front and to the left and right. When one comes on you have to bop it to make it go out and the next come on. You get your time measured to bop out all the lights. It will be a different order time each time. It will sharpen your reactions no end and the time improvement is measured and recorded.
