Brian Kretsch: Owner
Brian Kretsch is the owner of TransformYourBody Fitness. I grew up in Minnesota. I am the youngest of seven kids. Family is very important to me and I believe in making my clients feel like family.
I have worked all over the country learning the best ways to lose weight, look great, and get fit. I’m easy to work with and I get you results. Everything is customized to your fitness level, your body, your goals, and your needs.
My goal is to improve my clients quality of life. What does that mean? Quality of life is when someone gets in better shape, not just physically, but also emotionally, and spiritually.
Many people tell me that by getting in better shape they perform better with more energy than ever at their job. Many clients get off of their cholesterol, hypertension, antidepressants, and other harmful medications. Many clients have better personal relationships because they have more self confidence than ever before.
Emma Van Donselaar : Coach
I started playing basketball and soccer when I was 4 years old and have always been surrounded by fitness. For as long as I can remember all of my free time outside of school and work was committed by athletics. I went on to play college basketball and college soccer, finishing my eligibility in 2019. After finishing college sports, I became very inactive and reached my heaviest weight ever. I decided I needed to make a change to improve my quality of life. I took a group exercise instruction class and it reinvigorated my passion for fitness—not to lose weight but to take care of my body and improve my overall quality of life.
My goal: help my clients reach their personal goals through a commitment to a client-centered approach (meaning respecting and helping to build the client’s dignity, autonomy, self-determination, self-efficacy, and self-expertise) while having fun!
Trenton Warnick: Coach
I was born into a family who’s always had a love for fitness and I have been learning from as early as the age of five years old. I’ve always used fitness as a way to help me stay not only physically healthy, but mentally healthy as well. Fitness has helped me at an early age from playing sports, to helping me serve in the Marine Corps. Noticing that so many individuals need help reaching their fitness goals has made me both excited and eager to want to be a part of their journey and therefore I have decided to further my knowledge through NASM and become a personal trainer!
