The result is lower body fat ratio and faster metabolism. Since an increased percentage of the athlete's weight is muscle tissue, the athlete can perform at a higher level of efficiency and performance. The increases in strength and efficiency of the body's metabolism and musculature while decreasing excess body fat leads to an increased potential for moving with speed, quickness and accuracy. However, it is not the strength training alone that accomplishes these increases. It is the applications of the total training cycles with the skilled sports specific training drills that effect change.
Confidence is everything to an athlete.
Don't underestimate the importance of this point.
