Helping High-Achievers Build a Body That Matches Their Ambition
Our Mission to Transform Your Lifestyle
At Total Life Fitness, we don’t believe you should have to choose between a successful career, a present family life, and an elite physique. Most fitness programs fail because they demand you revolve your life around the gym. We’ve flipped the script. Since 2012, we’ve specialized in lifestyle-integrated transformation, helping over 2,500 parents and busy professionals lose body fat and gain functional strength while keeping their social lives intact.
Our philosophy is simple: Fitness should be the fuel for your life, not the thief of your time. We combine the precision of sports science with the reality of a 50-hour work week to deliver results that don't disappear the moment you go on vacation.
Meet the Visionary
Luke Briggs
Founder & Head Coach
I’m a husband, father of three, and founder of Total Life Fitness. I’ve been coaching since 2012, helping over 2,500 clients transform their bodies and lives.
After spending eight years as an in-person trainer, I saw a major gap - traditional coaching focused only on the 3 hours in the gym, but not the other 165 hours that truly determine success. That’s why I took my coaching online, providing parents, busy professionals and even retirees with a sustainable, science-backed approach to getting stronger, leaner and more confident without giving up their lives.
I understand the challenges of balancing a career, family and social life while trying to stay fit. That’s why our coaching focuses on real-world solutions - no extreme diets, no cutting out your favorite foods and no spending hours in the gym. Instead, we help clients build strength, boost energy and create habits that last.
I’m proud to lead a team of dedicated coaches who provide personalized guidance and support every step of the way. Each of us is passionate about helping high achievers unlock their full potential through fitness because we know firsthand how it can change everything.
I’ve been featured in EliteFTS, Yahoo, Breaking Muscle, Stack and Muscle & Strength, but my real passion is seeing clients succeed in their journey to better health and fitness. Our approach works anywhere, anytime and for anyone who wants real, lasting results.
COACH
Mark McCoy
Relatable Results
He’s worked with HUNDREDS of clients inside Total Life Fitness since 2020.
Mark himself lost over 60 pounds in his late 40s and early 50s and has now sustained his results for years.
He practices what he preaches, and our members love working with him because of how relatable he is - he achieved his results even with working 40-50+ hours as a mortgage lender and having a wife and two kids.
Mark is a certified nutrition coach (Nutritional Coaching Institute) and delivers actionable, no-fluff advice so our members know exactly what to focus on each week.
COACH
Lexi Casselton
Women’s Health & Metabolism Specialist
She’s one of our women’s health specialists, with extensive knowledge around hormones, metabolism and all topics related to women’s health.
Coach Lexi herself overcame an eating disorder and understands both the art and science of body transformation very well.
She’s given a number of amazing talks to our members about alcohol and its interaction with hormones, how to read protein supplement labels, the impact of stress and cortisol on transformation and more.
Lexi has a degree in exercise science and is a certified personal trainer through the International Sports Sciences Association, and she is a voracious learner and stays on the cutting-edge of research and practical application so she can deliver the best possible results to the members she coaches.
COACH
Christina BROWN
Women’s Health Specialist
Christina is one of our women's health coaches, specializing in helping women navigate perimenopause and menopause through sustainable nutrition, strength training and lifestyle habits that fit real life.
After spending nearly 30 years trapped in the cycle of dieting, overexercising and struggling with body image, Christina understands firsthand how frustrating it can feel when nothing seems to work. It wasn't until she shifted her focus from restriction and perfection to balanced nutrition and strength training that she found lasting results and, for the first time, genuine confidence in her body.
She is passionate about helping women break free from the all-or-nothing mindset, build strength, improve their health and create habits they can maintain for life. Christina believes that lasting transformation comes from consistency, not perfection, and that every woman deserves to feel strong, confident and at home in her body.
Christina has been in the fitness industry for more than 20 years. She holds a master's degree in exercise science, is an ACSM Certified Personal Trainer, an ACE Certified Group Fitness Instructor and a Precision Nutrition Certified Coach. She combines evidence-based coaching with empathy, practical strategies and ongoing education to help every woman she works with achieve lasting success.
At Total Life Fitness, we focus on the other 165 hours of your week. My goal is to provide parents, professionals, and retirees with a science-backed, sustainable bridge to peak health.
