Everyone wants to run faster, right? Part of getting faster is of course doing the shorter repeats; one must build that explosive power of course. BUT, there’s another part to getting faster and it’s training your BRAIN and nervous system to respond at a quicker rate.
A runner can’t utilize that explosive power to run faster without the nerve and synapse networks first being created to ‘tell’ your foot to move faster off the ground. Isn’t science and the brain cool?
