All you need is a wall, and a tennis ball. The exercises that europeans like Tretiak first introduced ( I guess? ).. Lotsa different stuff you can do there. First try catching the ball (throwing high speed at the wall) with bare hands, throw catch, throw catch.. that way at least for me when you put on your gloves they it feels sooo much easier, and this helps. Once you get good at this, try throwing it with your eyes closed, and opening them when you hear the sound of the ball hitting the wall, and catching it there. I do this just as a time-waster during boring 2nd periods of NHL games on tv, afternoons when I have to kill time.. etc.
