text: i am 13 and i weigh 160 pounds. how can i make myself faster in the 40 yard dash? it is for football and i have all summer to work with. a few simple things will go a long way. stay active all summer so you get in great shape. work on staying low when you start and getting up to speed very quickly. you can do jumping drills to help get more explosive. also work on your sprinting form, learn about proper form and train with a friend so you help each other out. better form and a better start mean a lot for the 40.  running a 40, resting 20 seconds then running another, resting 20 and running another, then taking a few minutes rest is also a drill that some of the college kids use before the nfl combine.
