What is Fit Body Boot Camp?

Fit Body Boot Camp is the world’s fastest growing fitness boot camp brand, and we offer our members around the world affordable, convenient, 30-minute fat loss boot camps that challenge the body and deliver results every time.

Our specialized Afterburn workouts use a combination of High Intensity Interval Training (HIIT) and Active Rest Training to get your body to burn up to twice the fat and calories that traditional workouts burn in only half the time. They also keep your metabolism working at a higher rate for up to 32 hours after each workout.

Every group training session is led by an experienced and certified personal trainer and is designed to be fun, high energy, and challenging so that you burn the maximum fat and tone your muscles.

We also modify our workout programs to fit your individual fitness goals and fitness level. Whether you're new to working out or you're an experienced fitness buff, our professional trainers and coaches will help modify every workout so that you'll achieve your goals!

Our workouts are done in a dynamic group setting which dramatically increases your odds of success through group accountability and an addictive atmosphere of fun and community. Plus, this empowers you to get personal-training-level results for only a fraction of what it would normally take to hire a 1-on-1 personal trainer.

Best of all, our program extends far beyond the four walls of boot camp. We support your success through personalized accountability to stay on track to your goals, nutrition coaching that shows you how to eat for weight loss without disrupting your lifestyle, and smart goal-setting and workout adjustments that make sure your body is constantly getting stronger, leaner, healthier, and more energized!

What's the secret sauce behind weight loss? What about success in general? It goes way beyond any workout, diet, or number on the scale. Beyond the Scale, Fit Body's first-ever podcast, tells the inspiring stories of people who've changed their lives through fitness and health. This podcast is your detailed blueprint to do the same, so tune in!

About Matt Wilber

Hi!, Matt here!

In September of 2013, I opened my first Fit Body Boot Camp in Grand Haven (my hometown) with the mission to change the lives of the Grand Haven community. My Team and I opened the Holland FBBC in November of 2014, Forest Hills FBBC in September of 2015, and Grandville FBBC in May of 2016.

In just over 3 years, our clients — we call them our “fitness family” — have lost over 70,000 pounds and 70,000 inches with our program. We have now helped over 85 clients lose 50 pounds or more, 5 clients lose over 100 pounds, and 1 client lose an incredible 178 pounds! My team and I have devoted our entire lives to learning everything we can about fitness, fat loss, and changing peoples lives through proper training, nutrition, and coaching. Trust us, we have over 17 years in the trenches in the training industry.

I personally grew up the token chubby kid and I absolutely hated it. Being overweight fueled me to learn everything I could about living a healthy lifestyle, training, and nutrition. My passion for learning drove me to get my bachelor’s degree in exercise science from Grand Valley State University as well as a master’s degree in exercise physiology from Western Michigan University. I have even worked with professional athletes as well as Division 1 athletes at the University of Michigan.

My greatest joys in life are seeing our clients not only transform their bodies, but also their lives! My life’s purpose is to impact our clients’ lives and empower them to reach their health and fitness goals! Josh will be running our Alpine Fit Body Boot Camp, so I am going to let him introduce himself.

Hello, my name is Joshua Johnston and I am so excited to help you to discover your inner potential! As someone who has worked both inside and outside the fitness industry, I completely understand how life can keep us from becoming the person we want to be. Here at Fit Body Bootcamp, we want you to be able to have 30 minutes a day to focus on improving yourself. When you walk through our doors, we want those 30 minutes to be the best 30 minutes of your day!

As a former athlete, personal trainer, and small group trainer, I feel I can bring you a fitness formula that will keep you encouraged, motivated, and hopeful for more. I am completely confident in saying that our team holds the tools necessary to help you reach your goals and beyond. As a team, we will help you develop the groundwork needed to cultivate a strong body and mind. We are completely committed to helping you establish a healthy lifestyle and habits that will lead you to success.

Here at Fit Body Boot Camp, we look forward to developing strong relationships with you. We want to make the Western Michigan community faster, stronger, and better. We sincerely hope that you take the opportunity to come check out our facility, meet our family, and make our sessions the best 30 minutes of your day everyday.

Dedicated to your success,

Matt and Josh
