Meet the Coaches

Macy Pruett: Founder & Head Trainer
Hi guys! I'm Macy Pruett, and I'm the head trainer at Fittest Core! I create all of the workouts for women and work directly with all of the coaches and manage the programming for Fittest Core.
Since becoming a mom, my goal is to impact as many mothers’ lives as I can by teaching them to love their bodies through realistic movement. Having a more personal impact on women has always been a goal of mine, which is why I created 1:1 Coaching. My favorite part of training is the relationships I get to build with women, so it's super important to me to create a community where relationships and trust can be built!
I became a personal trainer over a decade ago and my qualifications are:
- Certified Personal Trainer with AFAA
- Pre-and Postnatal Trainer with AFPA

Fiona Langham: Trainer
Hi I’m Fiona! I’m 39, a wife, and mama to two toddlers.
I’m originally from the UK. Moving to Nashville in 2013 to pursue music. My true passion for health and wellness began when I moved state side. I started personal training and running a women only bootcamp. I am very passionate about helping women feel their best selves. As a mother of two, I know that it’s hard to prioritize your health, so it’s my job to guide you to your goals.
Macy and I met through social media in 2020. We met up for outside lunches during our lonely COVID/lockdown first pregnancies. We shared our fears for motherhood and supported each other as best we could. I’m excited to join her team and connect with all you mamas. I can honestly say that you are in great hands in the Fittest Core community. It’s so much more than just workouts, it’s building relationships that will ultimately make you stronger in body and mind.
I can’t wait to see you all hit your goals and to most importantly feel great.

- Pre and Post Natal with ISSA

Angela Threeths: Trainer
Hey Ladies, I’m Angela! I strive to help women learn more about what their body is capable of doing, through every phase of life. As women and as moms, our bodies are changing constantly and it can get so confusing. My goal is to eliminate the guesswork for you so that you can focus on yourself and your journey!
I combine my knowledge as a physical therapist, my passion for fitness, and my love for moms whenever I work with a client. I love the bond that you build when you work 1:1 with someone and I can’t wait to be a part of this community!
I have been training for over 10 years and my qualifications are:
- Doctorate of Physical Therapy
-Pregnancy and Postpartum Athleticism Certification from Brianna Battles

Lauren Robinson: Trainer
Lauren is a wife and mom to her two boys! She has been in the health and fitness space for over a decade, and that passion for health drove her to become a nurse 7 years ago. During her first pregnancy, she realized just how big of a gap there is for moms wanting to become their fittest and healthiest selves, so she became a Certified Personal Trainer and Nutrition Coach (NASM) and Women’s Coaching Specialist (GGS). She has spent the last 3 years dedicating her coaching skills and building relationships with other moms to help them become their strongest, most confident selves. She is thrilled to be a part of the Fittest Core Team to continue coaching other mamas and showing them what they are fully capable of- whether it’s through pregnancy, postpartum, or later stages of motherhood!

Kerrie DeFalle: Trainer
Kerrie is a wife, mom of 2 ages 1 and 3, PE teacher and ACSM certified personal trainer. Raised by active parents, health and fitness has always been a priority. Growing up, with a liver condition that affects the pulmonary system, she learned the importance of staying active and being strong. This inspired her to become a PE teacher and personal trainer in college. 15 years later, her passion for helping women get strong and live an active life, specifically moms, is stronger than ever, being a mom herself. She believes motherhood is even more reason for women to take time for themselves and prioritize their own health and fitness goals. She is so excited to be a part of the Fittest Core team and help even more women become stronger and healthier for themselves and their families.
