Having been an NCAA Division I athlete, I know about this topic from personal experience as well as from a personal trainer's point of view..... You can improve your maximum running speed and other types of running speed with proper training!
Just last summer, a middle school client decreased his 40 yard dash time by 2 tenths of a second! That's a huge improvement! Imagine yourself improving your 40 yard dash time from 4.5 seconds to 4.3 seconds! The NCAA Division I coaches would take notice of you in a hurry!
Train hard and smart to get faster!
