COACH

Tim Rainer

BS Allied Health, CSCS, CF-L1, USA Weightlifting, ASCM cPT

I'm most fulfilled when I get to show someone how strong they can be. As my career and life have advanced I've found myself training to be the best father, husband and dog dad possible.

I grew up in Mount Vernon, Ohio surrounded by corn fields. During my senior year of high school I broke my back, and eventually recovered well enough to play NCAA College Baseball. I had developed a desire to help others become resilient physically and mentally during my time there. After my baseball career I moved on to Professional Powerlifting, Crossfit, Spartan races, etc. and have spent my career helping others reach massive goals as well.

COACH

Ashley Rainer

BS Kinesiology, Precision Nutrition, NASM cPT, USA Weightlifting

My professional goal is to teach women how to reach their nutrition and fitness goals without sacrificing their quality of life.

My personal goal is to show my daughter that she can be strong, confident and unbothered by the standards of social media. I was raised on a dairy farm in Green Bay, Wisconsin and have always appreciated the work ethic that taught me. I was active in sports my entire life but during my time at the University of Wisconsin I realized I wanted to help people transform physically and mentally. I have 15+ years in the fitness industry and am still fired up to help my clients reach their goals.
