In this book Dr. Yessis delves into the major body actions used in producing force in all hits. He explains in detail the three actions that produce up to 80% of the total force produced in hitting. These actions are explained in detail using the major sports that require hitting such as baseball, golf, tennis and MMA/boxing. Also looked at are less force producing actions that when combined with the major actions, produce the total force seen in the hit. The more these actions are learned and perfected the more successful you will be at hitting and you will also have greater accuracy.
