Although all these athletes train with weights, they all achieve different results. Speaking on this topic in his book, Supertraining, sports scientist, Dr. Mel Siff, says Finnish researchers found that of these three types of athletes, the Olympic-style weightlifters were the most powerful. Says Siff,  The special advantage of high-velocity concentric training [such as the Olympic lifts] is tat it conditions the nervous system, whereas lower-velocity training [such as typical bodybuilding exercises] is better suited to development of muscle hypertrophy and slow-speed strength. Let s look at a practical application of the specificity principle. <br><br>For improving jumping ability, a begnner can make excellent progress on powerlifting exercises such as the squat and deadlift, take it to the next level with more explosive lifts such as the power clean, and finally, take it to the highest level with specialzed jumping activities such as plyometrics. To achieve the highest levels of specificity in improving running speed, BFS offers athletes two important running tools: sprint sleds and sprint chutes.<br><br>A sprint sled is a weighted sled that attahes to your torso with a harness, whereas the sprint chute is a parach
