Anna Heffernan
Certified Personal Trainer
Even though Anna is originally from Madison, Wisconsin, it wasn’t until she lived out in Los Angeles that she fell in love with the fitness industry!
Having tried numerous gyms in California, Anna realized that every gym had something different to offer their clients and she wanted to become a part of it. Anna has 3 years of boxing experience and has even trained for a fight herself. MMA is her favorite sport to watch because it involves a lot of technical work. Having stepped outside her comfort zone by learning to box, is what led Anna to encourage others to try new things! Whether it is picking up a heavier weight or trying a new exercise, Anna loves to help others gain confidence. If she isn’t in the gym training herself, you can probably find her at the dog park or reading a thriller novel at home!

Corinna Humulos
Certified Personal Trainer
In order to utilize my compassion and love for empowering others, I obtained my Masters degree and began my career as a Social Worker in 2009.
After having two children and becoming consumed by motherhood, I rediscovered the importance of self-care and refueling my soul. I have always had a passion for fitness and staying active, but I was inspired a few years ago when I discovered the powerful transformation that comes with weight training. Lifting completely shifted my mindset to celebrate what my body can do, using food as fuel, embracing opportunities for growth both physically and mentally, and finding my power. I obtained my certification and began personal training. I am passionate about helping others find their power, gain confidence, take control of their health and find joy in the process of getting stronger.
When I’m not at CFS or working out, I am busy with my children, running my personal training business and I am a Medical Social Worker at St. Mary’s Hospital.
Zeenaz Bednar
Certified Personal Trainer
Zeenaz is a certified personal trainer and nutrition coach.
She has always had a passion for how things work and has finally found a way to combine her passion for science with fitness, and believes this is one of the main reasons she loves helping people transform their bodies, and help people reach their true potential through fitness and nutrition. Her passion for lifting and nutrition began when she started noticing how empowering being strong physically and mentally felt. To carry all your groceries up in one trip is amazing and that’s how she wants her clients to feel! She wants to empower people of any gender and age to feel confident in the gym and to not be afraid to just start somewhere! The rest of the progress and results will come with the right coach, a healthy mindset, and consistency. That mantra motivated her to compete in her first physique competition and is excited to take the lessons and knowledge learned while in prep to help her clients achieve their goals no matter how small or large they may be. As a mom to one sassy little 8 year old girl, working a full time job, and the desire to take time for her own hobbies, she understands the struggle to fit everything in a day, and has helped her clients prioritize the gym and eating while also maintaining their normal routine. When not in the gym, she is most likely doing her daughter’s nails, hiking, biking, cooking, or listening to podcasts.

Michelle Hoeft
Certified Nutrition Coach
After spending time in HR, Accounting, Business Administration and private school admissions, I chose to step away from the daily grind to focus on my family staying home for nearly 5 years.
As a wife and mother of 2, my focus was often on caring for the needs of others. I began to focus on my physical needs by joining running groups and doing large group classes (HIIT/Boot Camp). But, there was always a missing component. Dealing with food sensitivities and digestive issues, food was often at the forefront of my mind. Yet, I had never learned how to eat correctly!
My path to becoming a Nutrition Coach began as a CFS Client. My passion for all things nutrition and fitness grew quickly as I began preparing for my first Figure competition. I loved when people would stop and ask about my journey. As they’d ask questions about nutrition, I realized how much I enjoyed being able to help educate others on the process.
I am currently working on earning my Personal Training Certification and will continue to work towards furthering my coursework with Nutritional Coaching Institute.
I am eager to share my knowledge and experience with CFS clients and help them make the life-altering changes I implemented in my own life. Learning to properly fuel your mind and body can lead to so many exceptional changes in the way you live. I hope to inspire others through nutrition and learning to make sustainable lifestyle changes that will benefit them for years to come.
