If you are a serious runner, you want to improve your ability to run faster and longer without injury. Many runners have bought better shoes or spent longer hours on the track trying to improve, only to end up frustrated with back and leg pain. But the secret to improving your run is simple--your stride is only as good as your physical abilities allow. Making a few simple changes in strength, flexibility, speed of movement, and technique will help you reach your genetic potential. In Explosive Running, Dr. Michael Yessis, a respected sports fitness expert, demonstrates the method he has used successfully with thousands of runners. His method consists of three overlapping steps all runners should go through in order to improve their performance and make the transition to effective, efficient, and faster running. Included are detailed discussions of the biomechanics of running, special strength exercises, stretching, troubleshooting common problems, nutrition for optimal running, and tips to maintain a running program. This book employs unique sequence photography that captures and analyzes movements that are key to a good running stride. Explosive Running will give you a much greater understanding of the sport and help you improve in a much shorter amount of time than most other books on the subject. Michael Yessis, Ph.D., is president of Sports Training, Inc., a training facility for professional athletes.
