Ok, since its the offseason, I spend this time testing everything, trying new things, analyzing…etc
this particular thing is right before getting into the blocks, "on your marks". i see maurice greene and boldon doing some bounding toe touches and then squatting, jeremy wariner doing a frog leap and then hip flexor stretch behind the blocks, and many others taking a similar yet slightly different approach. which of these give good results, how do they work, etc. feedback needed, thanks.
