As a mother of two teenage boys and a baby girl – I know what it means to be busy with the activities that children can so easily bring into our lives, such as hockey, crew, school, and anything else their schedule begs of me. Pregnancy was also difficult in the weight gain arena, as I gained 70 pounds for all three babies for a total of 210 pounds! I understand the struggles of weight loss first hand and also have the tools to be successful.

To keep care of my health and the health of my family, I incorporate strength training, cardio, and clean eating into our everyday lives. I believe in the 80/20 rule and stay on my maintenance clean diet 80% of the time, 20% of the time I enjoy ice cream, pizza, or indulge in extra korean BBQ!

I am not always able to find time to do a workout, which is true for many people, but that just means that I have to make time. When I make the time to work out, I feel healthier, more alert, strong, and ready to take on the day. The best gift that I can leave for my children and clients is the knowledge of eating healthier and working out so they can live with the energy to take on their days and feel their best.

Manager / Chief Inspirational Officer / Nutrition Coach and Personal Trainer

The amount of gratitude I have from being part of the Erin Cantrell Fitness family is more than I can express! To say I am thankful would be an understatement. Becoming a certified personal trainer was not on my “vision” board. It wasn’t until after I had my son that I truly started to invest in myself. After seeing that discipline and consistency truly did make a difference, I was hooked! Who would have thought becoming a NASM Certified Personal Trainer would be such a gift! It has inspired me to live my best life and to teach others how to lead by example, dream big, and never give up. Know this: You CAN start over each morning....you win when you show up!

Dylan Rodrigues

Personal Trainer

I come with a background of six years in the Army. During my time in the Military, I earned several high achievements for my physical performance; to include the highest score in our Physical Training test out of 100 plus soldiers while in Basic Training, as well as an Air Assault Badge during Active Duty. However, my passion for fitness began well before the Military. From a young age I have always been involved in sports. As I grew older, I realized how fitness could forever change my life for the better – both physically and mentally; especially after becoming a husband and a father. In 2022, I completed my 1st half Ironman triathlon; it was one of the best experiences of my life. Looking forward, I plan to continue pursuing this sport and eventually completing a full Ironman 140.6. Triathlon has taught me a lot about preparation for endurance sport. For events like this you don’t just sign up and go. It requires a lot of time, blood, sweat, and sometimes tears! “Failure to prepare is preparing to fail.” I have gained so much through fitness and I want to instill these same values and the confidence I have been able to gain in each and every person that I have the opportunity to train.


Karthik Muruganand

Personal Trainer

My journey with fitness and wellness has been a long, winding path. Growing up, I struggled with my body image, constantly struggling to be comfortable in my skin. Inspired by my older brother, I decided to join rowing in high school. Through rowing, I could put my problems aside for a few hours every day. It allowed me to tie physical fitness with mental wellness while working on my path to self-acceptance. I currently row for the University of Michigan while pursuing a degree in Movement Science. With my personal experience and extensive education, I strive to help others find beauty in the process!

Personal Trainer, Boxing, Group Classes

My passion for fitness and physical movement kicked off when I was just a toddler. After receiving my BFA from New York University I knew I wanted to build a career I was passionate about, and coaching found and inspired me. I have instructed everything from Kickboxing, Strength & Conditioning, Brazilian Jiu Jitsu, to OCR Training and am NCSF Certified. My goal is for you to leave every session inspired, motivated, and with a fierce sweat glow!

My words to live by: “Don’t limit your challenges. Challenge your limits.”


Lexi Dixon

Personal Trainer & Group Classes

Since I was a little kid, I have always been passionate about fitness. Whether I was playing a sport, running around outside, or following a workout video, I always found a way to move my body. After high school I went on to complete a bachelor's degree at Central Michigan University. While I was at college I tried to stay active, however, I fell out of a routine and felt lost in the gym. 

During my senior year of college I found out I had 3 autoimmune disorders. I knew that I needed to make a change to better myself. Balancing my physical and mental health became of great importance to me. This was the push I needed to get back into making my physical health a priority. After college and finding my love for moving my body again, I became NASM certified as a personal trainer and corrective exercise specialist. 

I love coaching and making fitness fun! The best part of being a coach is seeing the progress clients make and knowing that they are bettering themselves. It brings me such joy to be a part of their journeys. I will forever be grateful for the positive impact fitness has had on my mental and physical health. I hope to help others have a positive experience with fitness and find a passion in it like I have.

Hey! I am a personal trainer and group class coach at ECF! I have been in fitness for the past 10 years and have worked with youth athletes, elderly populations, and everything in between! I earned my B.S. and M.S. in Exercise Science and currently preparing for Physical Therapy school. Personally, I am training for CrossFit and Ironman Triathlons. Outside of the gym, I love hanging out with my 4 dogs, visiting national parks, and just being outdoors.

I’ve always been unable to stand still, so workout classes showed up early in my life. I’ve been teaching for years, from HIIT to Pilates and back again, I love helping people find the right workout to move their bodies and feel good. My goal is always to build confidence and reach your goals, whatever they may be.
