TGS/SP Training:

TGS has developed sports training and conditioning techniques adopted from many sports, adapted to create efficient athletic performance. Many referred to this style of sports training as cross – training. TGS began to develop our training techniques before the term cross-training became popular. As a result, we understand what is needed to develop an ATHLETE.

We apply several known theories and principles of Kinesiology and Olympic athletic preparation, to help develop our athletes. We use the training principles and techniques of boxing, football, martial arts, track and field, soccer, and basketball. The sports training and preparation requirements for these sports have influenced the development of the unique True Grit Sports / Sports Performance training.

Our understanding of the principles of human movement and the efficient use of movement is applied in the development of our athletes. The adjustments required specifically for the athlete and the sport are evaluated and determined. Therefore, we tailor the training to the athlete and to the sport. At TGSC we develop an athlete, who plays sports. Any sport!

Our emphasis is on the male or female athlete’s individual needs and abilities. Our plan for your organization or athlete is to build on your current athletic status. We will continue to develop agility with speed and balance. We will continue to developed core strength to assist with the development of speed. We will continue to develop balance through the development of lateral and vertical movement. This is all accomplished through various TGS/SP - sports conditioning drills and exercises.

Our training schedule will be designed to develop your athlete or athletes throughout the season. We will not train or develop your athletes to their PEAK PERFORMANCE, before he or she needs to perform at his or her best.
