I know they do work and all, but if I did 10 50 yard sprints a night every night for the summer, about how much time will I take off from the start of the summer?
I play hockey and me and my coach agreed I need more speed, he suggested 50 yard sprints so I just started doing them and I just want to know how much it will help.
Also, are there any other ways to gain speed in addition to this?
