Our Team

Kara came to us from Fairfax, Virginia. She started attending Stroller Strides when her son was 2 months old and became hooked. After maternity leave, she started taking Body Back classes and then became a certified Fit4Mom instructor. Advancing in her fitness goals while gaining more knowledge about pre and postnatal exercise and health has become one of her passions. Kara is certified in Stroller Strides, Stroller Barre, Body Back, and Fit4Baby. Her classical dance training, knowledge of anatomy and physiology and advanced degree in Early Childhood Education help make her classes engaging, challenging, effective and fun!


Hey mamas!

I wanted to take a moment and introduce myself! My name is Sarah Johnson, and I am the owner/ instructor of FIT4MOM St. Augustine Beach.

I am a mother to two wild and adorable children, Norah (4) and Micah (2).

My background in fitness began in college where I earned my degree as an occupational therapy assistant. Right out of school I worked in rehab for almost three years, and once I gave birth to Norah, I decided to become a stay-at-home mom.

As knowledgeable as I was about the body, muscles, health, ect, I never truly applied it to myself. After having my daughter I quietly dealt with post partum depression which resulted in unwanted weight gain.

After about 9 months I decided it was time to change my lifestyle and take care of myself so I could willingly give to my daughter and my family the way I knew I needed to. No more giving from an empty cup.

I will never forget the first Stroller Strides class I attended. The instructor was encouraging, uplifting and made me feel like a million bucks. Nothing I had ever experienced before in the fitness arena. The women I was surrounded by were just the same. We were all in this together. Motherhood, fitness, and life!

I want to bring that same vibe to the tribe here in St. Augustine Beach/Palm Coast community. Camaraderie, solidarity, and a spirit of encouragement and empowerment.


Born and raised in St. Augustine, Mandy was one of our founding mamas at Fit4Mom St. Augustine Beach. Before becoming a stay-at-home mom, Mandy was a fourth grade teacher and spent her free time enjoying the outdoors with her husband, who shares her passion for living an active lifestyle. After giving birth to her son Brady in September of 2017, she began attending Stroller Strides classes at eight weeks postpartum. Mandy initially started attending classes to work off the nearly sixty pounds she gained during her pregnancy, but soon realized she wanted to exercise for more important reasons than the numbers on the scale. Mandy now exercises to be healthy for her son and wants him to grow up seeing the importance of hard work and self care. She is passionate about her community, encouraging other mamas, and supporting them in their fitness journey as they work hard to be the best versions of themselves. Mandy is a certified group fitness instructor for Stroller Strides and uses her background in Elementary Education combined with her knowledge of prenatal and postpartum fitness to make her classes fun, encouraging, and challenging.


Chelsey's FIT4MOM journey began shortly after giving birth to her first son, Lane. As a first time mom, Chelsey was searching for a fun way to get fit, healthy, and meet new friends. She was born and raised in St. Augustine, and was thrilled to find FIT4MOM St. Augustine Beach that were a group of like minded moms so close to her home. She began attending Stroller Strides and Stroller Barre classes a couple times per week. Shortly after joining, she added Body Back into her weekly routine as well. After seeing such amazing results, she sought out the opportunity to bring these great programs to other moms. She is very excited to head up our Run Club and all the adventures it will bring. Chelsey has an educational background, and a passion for fitness and helping others. She is excited to be a part of this community, and to help all moms reach their fullest potential!
