Consistency: if you want to do anything well, you have to do it often. This applies to exercise. A recent study done by the University of Georgia showed that regular exercise improves oxygen consumption by 11 percent and muscle strength by 33 percent, compared to no exercise. These two factors are key in almost any type of physical performance a person could engage in. The more oxygen you consume, the more efficiently you can process it.

This, combined with stronger muscles, allows you to labor with less stress for longer amounts of time. A fit body makes movement easier and performance higher. The surest way to attain a fit body is through consistent exercise
