  Bill Sonnemaker, MS - brings 12+ years of business management and fitness training experience to Catalyst Fitness, which manifests itself in the personal success stories of countless clients, students and companies.

He is also an Examiner for the Medical Fitness Association (MFA) and both a media representative and "Fly Solo" Mentor for the National Strength and Conditioning Association (NSCA). In addition, Bill has professional experience as a CDC Research Scientist and a strong academic background in Molecular Biology, Molecular Genetics, and Biochemistry.  His scientific understanding of the human body, with its unique composition and chemistry, lends itself well to a logical approach to individual fitness training.

Although science is the foundation of Catalyst Fitness' approach to fitness and the basis for the remarkable results of the company's clients, Bill also understands that there is an art to working with people.  Catalyst Fitness' underlying philosophy is integrating the art and the science of fitness.

Bill is a long-time fitness advocate and a former member of the U. S. National Wrestling Team.  He has earned incredible personal results, participating and winning national-level Wrestling, Bodybuilding and Jiu Jitsu competitions.  His personal success, passion for life-long fitness, client care and concern, and overall enthusiasm provide Bill the unique ability to bring out the best in those that he works with.

When working with clients, Bill focuses on two key areas. The first is a proper Kinetic Chain Assessment and the second is Functional Training.  Assessing the combination and interrelation of the nervous, muscular, and skeletal systems ensures optimal and efficient human movement.  He uses a Functional Training model that involves exercise prescriptions specifically designed a training model that involves exercise prescriptions specifically designed to improve a client's performance of activities inside and outside the training environment, including specific movements involved in work, sports or other activities of daily life.

"If one component of the Kinetic Chain is not working properly, the client's movement is ultimately effected.  When a client's ability to move properly is affected their performance decreases and their health is compromised; specifically they are more susceptible to injuries.  A Kinetic Chain Assessment helps to provide the information I need to design an exercise program which meets the musculoskeletal needs of each client."

Educating his clients sets him apart from other trainers. "A lot of trainers don't want to impart too much information to their clients for fear the client will leave them and train on their own. But, I've never lost a client because I've taught them too much". Once clients achieve their goals with Bill, they're hooked. They either set new goals or continuously check in for periodic program updates.
