My style is based on slow and controlled resistance training to maintain/regain strength, with focuses on pelvic floor stability, rehabilitation, and recovery. My nutritional coaching centers around creating a foundation for improved health and nutrition with realistic expectations. These foundations are based on a client’s past and present experiences, their current circumstances, and to ensure optimal pregnancy, birth, and postpartum needs are met.

My Training Style

My Fitness Journey

I began my journey over ten years ago in my college gym which initiated a drive to challenge myself and consider the importance of my long term health. From there, I continued to escalate workouts and nutrition which eventually became a growth opportunity in recognizing signals from my body.

After years with restrictive eating, injuries, physical therapy, even surgery, I developed a new prospective to my training programs. I encouraged slow and controlled movement, working on foundational exercises, and mind-body connection. Thus emerged my core personal training principles and nutrition coaching guidelines.

I wish to share these core concepts with the women and provide guidance with those who are looking to improve their health. This led to Fit By Amanda being created; an intimate coaching experience, with personalized coaching for women.

My Goals


I was recently featured in an article where I shared my journey of combining expertise in audiology and fitness to empower women in their health journeys. The article highlights my approach to personalized coaching, my commitment to creating interdisciplinary collaborations with medical providers, and my mission to challenge societal norms around body image and nutrition.

Discover how I help women build up their confidence, improve their health, and create sustainable habits.
