Many dynamic movements with a medicine ball can be performed at high speeds and will keep the body warmed-up and ready for serious athletic training.<br>Let me give you an example of the value of adding medicine balls to traditional training from my years as a strength coach at the Air Force Academy. During the off-season the  skill players on the football team would lift on Monday, Wednesday and Friday, and pes not really anyone who has stepped up to assume the role of the dominant jumper yet."<br><brH֛sw+YFB#4{$8VOPvԚ8Ccp,x<})IW(xTmƯ=ɯC FUy5[MRaUІ$mݴo=*SH\nPᵁFƎdfa!ƁwpqJК@Dd :P%^\(2:ǽCq/~Wp -h&ڮo}$[urLm]y إQrvwYk®H^87 39=(%חonϾz u9/-38 _ְaoyN;wm+_uF#F+RKL<4x̃  u~РU`P workout, and when I'm not competing I'll be running and lifting." But in the history of high jump training, Amy admits that such discipline and dedication was considered the exception rather than the rule.<br>"In the past there was more of a laissez-faire attitude toward high jump training, and a lot of the jumping workout would be occupied by sunbathing on the high jump pit," says Amy. She recalls one story of two German high jumpers who entered a competition in the 70s. When they found out that the meet was goig to take several hours, they left the meet and went down to a local coffee shop and had a few cigarettes and several leisurely cups of coffee. Says Amy, "When they came back to the meet they found that they had misjudged the time and there was only one jumper left before them, so they had to warm up in a hurry. They ended up jumping pretty well because they were great natural talents, but these were athletes who really didn't take care of their bodies, and you wonder what they could have done if they had taken better care of themselves."<br>A major portion of Amy's training i the Olympic lifts, but she also performs several auxiliary lifts for the lower back, abs and the upper body. "It's important to keep the upper body strong for coordination," says Amy. "At the takeoff you really have to move the upper body--you can't just be a limp noodle." She also says it's important for jumpers to perform specialized exercises for their ankles. "You get a lot of power from your feet, and if your ankles are hurting you're going to suffer. I do all kinds of ankle strengthening, such as picking up sand and running on the toes to strengthen the arches, surgical tubing exercises, and rocker boards--I work on my ankles a lot."<br>For younger jumpers, Amy believes in the importance of being exposed to a variety of sports. "You learn a lot through other sports and through competition. It's just like your academic studies--you need to become a student of your sport and learn all there is about it. The high jump takes a lot of technique, but you can't stop there. You need to learn the mechanics, the physics and the psychology of the jump to really succeed."<br>Amy has given quite a bit of thought to the psychology of sports and believes there are some truths behind the stereotypes about track and field athletes. She says that sprinters are confident, bordering on cocky; throwers are the jokers and are laid-back; pole vaulters are the daredevils, and distance runners tend to engage in strange rituals lower their time to 11.9, but such training details mean a lot to a 10.4 sprinter trying to lower their time to 10.39. <br><br>Testing<br><br>In addition to their use in developing power, medicine balls are a great tool to determine if an athlete needs to concentrate more on increasing strength or power. A great test, and one that is used extensively in Europe, is to have an athlete throw various weights of medicine balls overhead
