The life preserving and life enhancing qualities of exercise have been well established. The exercise revolution which began some years ago is still in my view the only way to improve your overall fitness. Whether, a world class Martial artist, soldier, athlete or just someone who wants to keep fit and healthy and you want more out of life, you need to be ready to commit more and invest more of your time into staying fit and eating right. 
While there have been innumerable diet plans and exercise programs all claiming to provide the fastest results,  we all know the basic equation to staying fit and healthy is regular exercise and proper nutrition. It has been called by many names, and presented in so many forms but all health and fitness programs boil down to these two factors: DIET and EXERCISE, if you want lasting results.  
Fitness is the general term for the complex changes that take place as a result of good, regular exercise. Among people there are many different definitions of fitness. Some focus on body shape others look for strength and muscularity. The nine components for fitness are: *Strength *Speed,*Agility *Endurance *Power *Coordination *Balance *Flexibility * Body control. It‟s obvious that some of these components are related to workload. For example: Power, speed, strength and endurance.
