Brianna Bernard

Brianna Bernard lost 100 pounds in one year! She is a single mom, personal trainer, nutrition coach, mindset mentor and corporate wellness provider who keeps busy women accountable for owning their health.

After gaining 70 pounds during her pregnancy, Brianna’s weight escalated to 245 pounds. This independent, do-it-yourself woman surrendered to the idea that she could not lose the weight alone after trying and failing at every diet and workout program on the market.

Instead, she hired a personal trainer and began exercising three times a week, incorporated lean proteins, vegetables, fruits, healthy fats and complex carbohydrates into her day, and the weight started coming off. In the first month, she lost 12 pounds. After three months, she was down 30 pounds. In six months, she had lost 50 pounds. And just before her one year anniversary at the gym, she had lost 107 pounds.

What keeps you motivated?

One of my top priorities as a mom is to raise my little boy to have a healthy relationship with food and exercise. In order to successfully achieve that goal, I know I need to lead by example. If I make exercise and nutrition a priority in my life, there is a greater chance that he will do the same for himself.

Why do you love to sweat?

Even if everything around me is chaotic (family/work/friends/etc), I am responsible for how I move my body. That sense of control makes me feel powerful in all areas of my life, both physically and mentally. And when I make time for myself, I can show up as a better mother, a better partner and a better leader for the most important people in my life.

What words do you live by?

At the beginning of my 100-pound weight loss journey, I told myself, “You are guaranteed to succeed as long as you don’t quit. You already know what it feels like to give up. What would happen if this time, you didn’t?” This theory holds true in every area of my life.

What makes you a kick-a$$ Oxygen Ambassador?

I’m not afraid to do hard things. One of my favorite quotes is by author and psychologist, Susan Jeffers, who said, “Feel the fear and do it anyway.”

After losing 100 pounds, my physical appearance might be the most obvious change, but the transformation that happened on the inside is by far more profound. Owning my health changed my life in every way. It changed my relationship with food and exercise. It changed the way I feel about myself. It changed the way I parent my child. It gave me the courage and confidence to leave people and places that were no longer serving me and become a single mom and fitness entrepreneur. It introduced me to competitive powerlifting, and the strength I found in that sport spilled over into every area of my life. And it inspired me to become a personal trainer and nutrition coach and help others become the healthiest, strongest versions of themselves.
