About Us


This dynamic duo began their weight loss journey in 2008. It all started when they decided to audition for NBC’s The Biggest Loser. After standing on line for hours in the grueling heat on the streets of New York City, they were seen by a casting director and were called back for a second interview. After the second interview, they were asked once again to participate in more of the casting process. Their hopes were high that soon they would be on the ranch, miles away from the stresses and distraction of everyday life, making their dream of losing their weight come true. Once they submitted the last piece to the casting puzzle they were told to wait for a phone call on a specific date.


They will never forget the day the phone call was supposed to come. As the day came to a close, it was evident that things were not about to change, as they had hoped. No ranch, no extreme weight loss, no possible million dollar prize.

But hope was not lost. Why stop now? Michelle had already auditioned for the show once before, obviously this just wasn’t the path they were meant to take. The effort that was put forth to get as far as they had for the show just proved how badly they wanted it and that they were ready to begin.

They sent letters to their loved ones stating they would be secluding themselves in order to focus and dedicate themselves to making their weight loss dreams come true. Life would only consist of essential daily activities such as working out twice a day, showing up for their jobs and eating right. This was their chance to finally lose the weight they had held onto for years. Their family and friends understood and cheered them on.

Since then, Michelle and Lisa have lost 240 pounds combined; Michelle, 155lbs of her own and Lisa, 85lbs (see Before and After photos).

They found success using a variety of different eating programs and fitness routines throughout their journey. It was important to them that they achieve their goals naturally without any surgery, weight loss pills or fad diets. This was truly a lifestyle change.

Through the weight loss process they gained a love for health, fitness and helping to inspire others to start their own journey. Michelle is now a NASM Certified Personal Trainer and Lisa plans to receive a certification as a NASM Fitness Nutrition Specialist sometime in 2014. By choosing to commit and overcome challenges, they were truly able to make the change; this is how they have become FourC Fitness.

Lisa Bio


I’m just a regular ole gal who enjoys working out, eating right and inspiring others to do the same. But it was not always like this.

I was overweight for the majority of my childhood. My earliest memory of being overweight was probably somewhere around age 8. I remember comparing my chubby knees to a skinny boy sitting next to me in school. I wanted skinny knees too.

I had to shop in different sections of clothing stores than the other kids. As time went on I got heavier and heavier. I didn’t have much of a concept of what was really happening with me I just knew it wasn’t normal. At middle school weigh-in day the nurse told me that I should “lose a little weight.” That only made things worse. My parents tried to help but as a kid I just felt ashamed, hopeless and helpless.

Come high school, I don’t even remember what my weight was. I couldn’t even tell you. I remember my dad talking to me about “missing out on things the other kids were doing” due to my weight. Three years into high school I started to finally take matters into my own hands and I successfully lost a handful of weight but nothing too major. When I did stand on the scale, I was 180lbs.

In college and after, I gained most of that weight back. When Michelle and I auditioned for The Biggest Loser, it had been years since I stood on the scale but figured I was around 200lbs. After we didn’t make the show and decided to lose the weight on our own, I officially weighed in at 215lbs.

I did well when we started things off in 2008, but I was not motivated enough to keep momentum on my own. Michelle was truly an inspiration to me and I would not have made it as far as I had if it wasn’t for her. Slowly but surely I began to try new exercise classes and actually enjoyed it.

Over the last 5 years I have lost 85lbs using many different weight loss techniques. My favorite thus far was following the 40-30-30 Formula which structures eating in a ratio of 40% Carbohydrate, 30% Protein and 30% Fat. This program sparked my interest in nutrition and my desire to learn more about how I could create fulfilling meals like this on my own and still see results. Therefore, due to the 40-30-30 method and my love of cooking and eating healthy, I plan to start and complete my certification as a NASM Fitness Nutrition Specialist in 2014.

The journey was not always easy. I found my stride with the Formula eating program. When I look back it’s a total blur! But the one thing I remember is the harder the workout, the more change I saw.

It was always a dream of mine since childhood to be a normal weight, whatever “normal” is, and I consider my weight loss a dream come true. If you would’ve asked me when I began where I’d be in 5 years, this never would have been an answer. I am truly honored that I can inspire others to change their lives.

My lifelong struggle with my weight has brought me where I never imagined I would be. Co-hosting a health and fitness show and a NASM Certified Personal Trainer were never on my list of future careers, but here I am, after losing 155lbs and finding my true path in life.

My weight began to fluctuate at the age of 8. My pediatrician suggested my parents take me to the Weight Watchers Youth program and so began my introduction to weighing and measuring my daily intake of food and water. An active kid, I was involved in dance and loved riding my bike, playing on the monkey bars and running around my house like I was the fastest athlete in town. But my weight continuously became the focus and struggle of my childhood and adolescent years. Kids can be cruel and I eventually self-fulfilled the prophecy that I was “fat”. Some excess baby weight and “chubbiness” turned into over 300lbs throughout the course of college and beyond.

My weight held me back from pursuing my dream of being on stage. I always felt as though I was meant to be an entertainer, but I constantly felt insecure in the Theater world. I felt comfortable with my friends, family & peers, but I didn’t feel I had what it took to make my dream a reality. I always said I would go for it after I lost the weight.

The opportunity to be on The Biggest Loser presented itself in 2007. This seemed like the perfect chance to lose the weight while being in the spotlight and to see if I could make my entertainment dream a reality. I made it to the final round of casting twice, but obviously I was meant to take a different approach to losing the weight and going for my dreams.

In September of 2008, after years of failed fad diets, cleanses and false starts – I finally embarked on my journey to losing 150lbs. My goal was to prove that it could be done without surgery or unhealthy measures, and I am proud to say that I proved that theory. When I started, I never realized the process that it would take to get where I am today. I originally gave myself a time limit, but once my life changed course, I learned that there is no short cut to changing your life for the better. The process takes as long as it takes and in the end the journey is what matters, not how long it took to get there.

As of today, I am still on the journey. Extreme weight loss has left me with excess skin and my new goal is to prove that the skin can be toned and tightened without the need for surgical procedures. Beyond that, my stretch marks will have to prove as the scars of my success and how far I have come. I may never have the perfect body, but this experience has given me so much more meaning in life than the perfect body ever could.

I find it an honor to inspire others with my story. My new dream is to host my own health and fitness talk show on network television with my partner Lisa by my side. I feel as though there are so many that can benefit from our experience and that need to know that anything is possible if you put your mind to it. There is a sea of information to weave through in finding what works in the world of health and fitness and we hope that our experience will help others to find their own path to success.

I am here to share my experience and help others in any way possible. If you would have told me that I would be where I am today, I never would have believed it, but I couldn’t be happier to share this journey with all of you.
