Hey, I play on the wing now, I think I'm 3rd fastest following our full back and scrum half/wing/center. I'm 5"10 and weigh 74kilos / 162lb. Anyway to the point, I want to increase my speed. At the moment, I spend a large proportion of my time in the gym on my legs, do interval training when I have time (rarely unfortunately) and do plyo's. Does anyone know any specific exercises, drills etc. that are good for increasing running speed?
