Injury Prevention

Grant Training Systems was founded on the belief that there is a better way to deal with: (1) lengthy injury rehabilitation after conventional treatment and (2) athletes not performing as well after surgery as they did before their injury. David Grant’s graduate degree in Kinesiology and Sports Medicine and his more than 10 years of experience in providing successful therapeutic treatment have demonstrated that traditional therapeutic approaches often do not deal with injury prevention and do very little to address proper movement mechanics. Injury prevention and proper movement mechanics are critical to avoiding re-injury and to attaining higher performance.
At GTS, we realize that injuries are inevitable in life, and we also know that it is not just the injury that needs to be fixed. It is also necessary to correct the dysfunction that caused the injury to avoid a recurring problem that could threaten an athlete’s career or make it difficult for parents to do normal things like play with their children.
GTS focuses on correct movement education and training. David teaches clients to unlock their body’s self-healing mechanisms and avoid re-injury while performing at peak levels. As David often says to his clients, “It is the victim (injury) that makes the noise while the thief (the physical dysfunction or cause) is quiet and causing more harm.”
