Revitalize Your Health and Fitness with Donna - Your Expert Exercise Physiologist

 About Me | Your Trusted Coach Donna Greetings, I'm Donna Medina, a 50 50 something exercise physiologist, consultant, and coach with over a decade of expertise in physical fitness and well-being. My primary mission is to empower women of all generations to enhance their health and mobility through evidence-based, long-lasting lifestyle transformation 

My fitness philosophy is simple: I provide advice, information, and services that relate to and educate my clients to support their goals and encourage exercise adherence. I have a strong behavioral change approach, which helps my clients establish discipline and solid lifestyle changes for better movement and internal and external strength.

When working with my clients, I meet them where they are each day and never push them harder than necessary. My desire is to promote a positive self-image and confidence by implementing a customized exercise prescription for each individual.

I began my own wellness journey in 2003, at the age of 30, when I was feeling slow, lethargic, and unhealthy. I had problems going up steps without being out of breath, and my unhealthy eating habits were taking a toll on my body. While chatting with my younger sibling about my physical issues, they suggested I consider exercising to help with my ailments. So, the following Monday at 6 am, I was at a gym for the first time in my life, and I stayed on the recumbent bike for 60 minutes and enjoyed every moment. That day marked the start of my wellness journey.

While working in the senior living industry and seeing the residents' mental and physical deterioration due to the lack of physical activity, I realized that exercise was more about improving internal systems for an enhanced quality of life while going through the aging process. I began to learn more about bodily organs, the deterioration of the musculoskeletal system, plus common conditions that affect the elderly, including Alzheimer’s.

In 2013, I obtained my first certification in Senior fitness, then in 2015, I obtained my personal training certification. Later that year, I opened Gymnanigans Strength Training studio and obtained several certifications along the way. In 2016, I officially started working full-time as a fitness professional.

Now with a Master's in Exercise Science and working as an Exercise Physiologist, my commitment and passion are to help develop stronger and healthier women over the long haul. My desire is to help individuals find actionable ways to improve their health plus gain skills in the process.
