About Us!
Driven by a passion to help others through fitness, Science Fitness Personal Training was founded by San Diego State University Graduate Michael Jensen in the year 2001. A pioneer of the personal training studio business model, Mike was determined to raise the standards in an industry filled with unsafe and inconsistent practices.

His business focus was simple, to deliver personalized fitness programs based on proven scientific principles guarenteed to achieve results. These programs were to be designed and delivered by only the most qualifed professionals in the industry. Trainers who hold not only a national personal training certification but also an advanced college degree and individual specialties. Progams free of gimmicks and fads, focused solely on each individual's unique needs. Private, personalized and professional to guarantee results.
These principles formed the core of Science Fitness then and still prove successful today as Science Fitness has delivered safe and effective fitness solutions enhancing the lives of thousands of individuals for over 10 years.
