I am a sophomore in high school and started on JV at cornerback with a 40 of only 5.5. I am 144 lbs and only 5' 6" but as of right now I am the projected starter for Varsity next year. (Every other corner was a senior and I'm the next best up). I despratley need to increase my speed for next year, so does anyone have a link to a web-site that has a specific program to increase my 40 yard dash? Thanks everyone.
