maybe its just me, but i find the best way to get out of your stance and into the acceleration stage in the 40 yd dash is quite simple.
To initiate the start, basically all you have to do take the arm thats on the ground and rip back violently. This will forcefully propel your body forward and it will make you fly out your stance. literally. Once i started doing this it cut my 40 yd dash by .25 seconds from a 4.60 to a 4.35 (hand timed of course, but if you add the standard .08 seconds you get 4.43 which aint bad)
Am I on to something?
Or am I insane? :eureka:
