Here is a good trick that serveral people here might know of...
First take one coin and flip it in to the air and catch it...
Then take anouther and add to the first coin (place one on top of the other) then flip each of them in to the air and catch both with one hand.
Then try flipping three coins stacked on top of each other in to the air and catching them...Keep trying this until you can catch more coins each time.....
I personaly am faster than ALOT of people i know...and i can flip and catch 2 coins with one hand easily. And usualy catch three coins with one hand as well..
Youll find when you practice some you get quicker. I used to only be able to catch two coins and now i can catch three with practicly no difficulty.
Not only does this help your speed/reflexes it helps your hand eye cordination....
Anouther thing that helps is being able to focus and push yourself to move faster....
I know plenty of people who could maybe keep up with me in a short sprint....the thing is....if both of us are in shape sooner or later either me or the other person will get in to a mindset that will allow that person to pass the other....By simply using your mind to make your limbs move faster than your thoughts....you see...by actualy thinking about your thoughts of moving you are making yourself go slower....dont think about moving simply move.
