You are in your 40s or 50s, you take your health seriously, and you have put in real effort: the workouts, the diets, the lifestyle changes. And you are still not where you expected to be. Not because you are doing something wrong. Because nobody has ever looked at what is actually happening inside your body first.
This guide explains why that matters and what it changes when you do.




I’m a Clinical Health & Performance Coach specializing in metabolic optimization, hormone health, and body recomposition through evidence-based nutrition, strength training, and precision lifestyle interventions.
My coaching integrates physiology, biomarker analysis, and individualized programming to address the underlying mechanisms limiting performance, health, and physique development—creating sustainable, measurable results rather than temporary fixes.
Whether your goal is fat loss, lean muscle development, hormone optimization, or peak physical performance, I provide a strategic, science-driven framework designed to help you achieve lasting transformation
Charles Thornton is a Functional Nutritional Specialist and the lead coach at Thor Strength Fitness next door.
Mission
To redefine health and performance by delivering individualized, evidence-based coaching that restores metabolic function, optimizes human physiology, and builds resilient, high-performing individuals.

My coaching philosophy is built on the intersection of clinical healthcare and elite physique development.
As an ICU nurse, I’ve witnessed firsthand the long-term consequences of preventable chronic diseases and understand the importance of addressing health before problems arise. As a competitive bikini athlete, I’ve experienced the discipline, precision, and consistency required to build an exceptional physique while maintaining overall wellness.
These experiences allow me to bridge the gap between performance and health. Whether you’re preparing to step on stage or looking to improve your body composition, strength, and metabolic health, I create individualized, evidence-based programs designed to help you achieve lasting results without compromising your well-being.

My Coaching Philosophy
Performance Through Health
I believe optimal performance begins with a healthy foundation. Every training and nutrition plan is designed to improve body composition while supporting long-term health, recovery, and sustainability.
Precision Physique Development
Drawing from competitive bodybuilding experience, I emphasize proper biomechanics, intentional exercise selection, progressive overload, and strategic nutrition to maximize muscle development and create balanced, stage-ready physiques.
Clinical Perspective
My nursing background provides a unique understanding of physiology, recovery, stress management, and metabolic health. I use this knowledge to develop programs that prioritize both peak performance and overall wellness.
Who I Coach
Lifestyle & Wellness Clients
Individuals committed to building lean muscle, increasing strength, improving metabolic function, and reducing their risk of chronic disease through sustainable nutrition and resistance training.
My Mission
I believe strength is one of the most powerful forms of preventative healthcare. My goal is to help every client build a physique that not only looks incredible but also performs at its highest level and supports a lifetime of health.
“True transformation happens when health and performance work together. Build a body that’s strong, healthy, and capable of performing at its highest level—for life.”
I’m Kat, a Certified Fitness & Nutrition Coach with over a decade of experience in strength training and fitness. My own journey has included everything from competing in powerlifting and CrossFit to learning how to make staying strong and active a sustainable part of everyday life.
My passion is helping others discover their strength, build confidence, and create habits that work with their lifestyle. Whether you’re intimidated by the gym, frustrated by a lack of progress, or tired of starting over, I’ll help you simplify the process and build a plan you can stick to. As a grandmother, I’m a firm believer that age doesn’t define what your body is capable of. Your strongest, most confident years don’t have to be behind you, they can be the ones you’re building right now.

Lost ~60 lbs collectively • Members for 6 Months
My journey to fitness has been for approximately 30 years. Over the years I've had multiple trainers, coaches and have worked with a ton of fitness professionals. My personal experience with Thorstrength Fitness trainers Charles and Khendal has been executed with such care and concern for my health and well-being. I had big goals in 2022 of entering my first ever bodybuilding competition. With their help I was not only able to achieve this goal at 64 years young but this team helped me transition from the stage with tools to use for a lifetime! Khendal and Charles training and motivation have far surpassed anyone else I've ever worked with! Their attention to detail is superb and done in such a loving and fun way that even the dreaded of workouts are made fun and easy to endure. The club environment is clean with updated equipment, really a sight to see! I can finally say I have found a fitness, lifestyle and competition HOME!
Theresa Johnson
Bodybuilding Competitor at 64 Years Young
I started at Thor Strength Fitness in March of 2022 after a discouraging process of trying to find a gym. Other places were trying to push keto and get thin fast programs or they were trying to talk me out of my goals of building muscle. TSF was one of the few that focused on goals per case. I have now been part of TSF for almost a year. I have been challenged more, grown as a person more, and made drastic progress towards my goals. Along the way, they have helped me rediscover my passion for weight lifting and spark a passion for taking better care of myself in all aspects of life.
