I have spent more than a year doing a lot of research on this subject. There are many books, videos, and websites that offer training for Agility and/or other sports. There are two types of athletes who need more agility: those who don't want to run, and those who want to run fast. This page is the source for agility training for anyone who wants to improve his/her agility. A study in which researchers asked people to perform a certain amount of squats while they were in a standing position. The study looked at the effects of using a higher or lower speed. The researchers found that subjects were more able to keep their balance if they were able to perform a slower (higher) speed. A fast and the fastest are two sides of the same coin. A fast runner is a much better athlete because he/she can control the speed of his/her foot and the body's natural reaction to movement. If a faster person cannot perform a higher speed, he/she can not improve his/her agility. In other words, the faster the runner, the less likely he/she is to be able to run fast. The researchers concluded that, in general, "speed training is a superior strategy for improving athletic performance in runners." A low speed is a low rate of movement.
