Our Trainers

Sebastian Garbsch CPT - ACSM

Sebastian Garbsch, founder of Formative Fitness, always tries to turn negative experiences into positive ones.

After losing his father at a very young age, largely due to an unhealthy lifestyle, Sebastian became committed to living a healthy, balanced life. For almost a decade, Sebastian has been sharing his passion for health and fitness with others, not simply through personal training, but rather by proactively helping them make health and fitness a part of their daily lives. Over the years, Sebastian has worked with clients from various backgrounds, with a wide range of goals, and tailors their programs to meet these goals. In addition, Sebastian has been extremely successful with working around clients who have limitations such as injuries and health concerns, when necessary.

Sebastian’s diverse approach to fitness is largely reflective of his passion for many physical activities, ranging from an immense list of outdoor activities, to traditional strength training and competitive sports. Sebastian’s only requirement of his clients (and himself) is that they strive to achieve their best.

Sebastian is accredited in personal training through ACSM, and also has earned an A.A.S. degree specializing in health and nutrition. Additionally, with the goal of creating a successful personal trainer studio, Sebastian earned his B.A. in Business, and holds various technology / accounting certifications.
