Greg Roskopf


Greg Roskopf has devoted his career to the study of the “cause and effect” of the muscular system and how it relates to pain.  As the author of the Roskopf Principle and the founder of Muscle Activation Techniques® he not only developed the MAT® program but also created a curriculum for this technique that has been taught to students all across the globe. Muscle Activation Techniques® fills the gap between the medical and the exercise fields. Greg has over two decades of experience applying MAT® to his clients and developing students into competent and respected practitioners.

Greg has worked as a consultant for various professional sports teams including: the Denver Broncos, the Utah Jazz, and the Denver Nuggets.  Beyond this, Greg works with clients at all physical capability levels who are looking to address challenges they experience due to injury, stress, or trauma to their muscular system.


Greg started his career in California as a Strength and Conditioning Coach at Fresno State University from 1985-1988. He received his Masters Degree in Physical Education with an Emphasis in Exercise Science from Fresno State University. Greg left his full time role as a strength coach in 1988 to develop a business in personal training and sports performance, yet continued to work with Fresno State’s medical staff, as a consultant, until he was hired to work full time with the Denver Broncos in 1997.

The development of Muscle Activation Techniques® began in earnest while Greg was working with performance athletes at Fresno State. Greg began questioning why some athletes would break down and get injured, while others could work through fatigue and achieve optimal levels of performance. Knowing that there had to be a fundamental explanation, Greg took his exploration efforts to a new level.

Greg began to focus on the biomechanics of the body and how the muscular system handles the demands that come with sports and/or training. He recognized that each athlete has his/her own specific limitations in muscle function that, if severe enough, could make certain athletes predisposed to injury. It was at this point when he began to focus on the specific muscular attributes that are consistent with injured athletes.

In this refined focus, he recognized that he had to individually evaluate each athlete’s muscular capabilities. It was these individual assessments that shed so much light on why conventional exercise programs were actually contributing to many of the problems that plagued athletes. Greg realized that most documented training programs (whether prescribed for performance enhancement or rehabilitation) could not be universally applied to broad group of clients with efficacy.

It was observed that clients with the most significant muscular imbalances were most likely to respond negatively to the protocol based programs. Greg found that if muscular imbalances existed, the exercise programs designed for these athletes would reinforce their compensation patterns, making the strong muscles stronger while the weak muscles remained weak, thereby, magnifying their imbalances.

This led Greg to believe that depending on the physical capabilities of a client, exercise based training programs may actually be contributing to their injuries, rather than preventing them. He theorized that by ignoring the individual mechanics of each person’s body, practitioners might be unknowingly inhibiting the injured tissue from properly mending.

Through the process of continually looking at the “cause and effect” of the muscular system and how it relates to pain, Greg has become recognized as a pre-eminent specialist in the improvement of muscle function. Jumping forward, today we see the results of his research in the program we now call Muscle Activation Techniques® (MAT®).  This systematic process (MAT®) is designed to evaluate and correct the muscle imbalances that contribute to chronic pain, injury and altered performance levels. It is a bio-mechanically based process designed to positively impact anyone affected with muscle weakness and its associated pain. Due to the impact of these MAT® principles in both the exercise and rehabilitation fields, MAT® practices are gaining recognition throughout all facets of sports and recreation.
