Anna Quinn, personal trainer

Anna Quinn, a nationally certified personal trainer for 7 years and counting, started her fitness journey with the sole intent of growing her glutes. She got certified through NCCPT, but her quest for knowledge soon led her to many more national certifications (including NASM, ACE, and numerous other speciality certifications). She also obtained a Level 1 Nutrition Certification through Precision Nutrition.

Her corporate world training journey started at Gold’s Gym in San Antonio, and ended at Lifetime Fitness in Dallas. Four years later, with a high demand and a loyal clientele, Anna started her own company as an independent personal trainer (Anna Quinn Fitness), training out of a private gym in Garland, Texas called “The Compound”.

A little over a year into her independent training career, Anna decided to expand her reach by offering online personal training. She hired a mentor to help her get started, and within weeks had 15 new clients online – all in different states, and all getting incredible results. She continued to refine her online coaching experience, providing form critiques via video assessments, doing video check-ins with her clients, and offering all of the workouts through a custom branded app. Soon after, she shifted her coaching business from “Anna Quinn Fitness” to “Modest Muscle”, and has now built a 3 person team to help insure her clients get the MOST accountability and encouragement there is to offer. From daily text messaging with her clients, one on one video chats, and weekly progress pictures & reports, Anna is now able to reach MORE people, and provide them with MORE accountability than ever before.

Although there are many approaches to reaching your fitness goals, Anna doesn’t isolate one single approach as best. She gets to know her client, looks at their current lifestyle / workout regimen, gets a clear understanding of their goals, and then creates a program to best suit each client. This individualized approach is why Anna’s clients are able to get (and keep!) such amazing results. With over a thousand documented transformations and testimonials, her credibility as a knowledgeable trainer, coach, and friend stands strong. Anna attributes all of her success in the industry to her hard work, her thirst for knowledge, and her reliance on Jesus Christ. She continues to train clients, hoping to improve as many lives as she can – from the inside, out.

Coach Sarahs Engelhardt

Sarah Engelhardt

Personal Trainer


  • ISSA

Sarah’s fitness journey started in the summer of 2016. She struggled with depression and strongly desired to better herself. Her passion for fitness grew when she discovered fitness not only helped her to be stronger physically, but mentally as well. She became certified as a personal trainer in 2019 and worked as a trainer for friends and family until she was given the opportunity to work for Modest Muscle Mvmt in June 2020.

Sarah cares deeply for people and desires to help others learn about living a balanced, healthy lifestyle. She strives to change the stigma of fitness being a diet and restriction from life. She wants to show others the values that come from fitness can transform every area of their life; strength, discipline, faith, commitment, loyalty, consistency, and so much more can be developed through fitness.

Sarah is a mother to one boy as well as a devoted Christian living for Jesus Christ. She is compassionate, empathetic, and genuinely enjoys helping others be their best self.
