You’ve heard the saying once a Marine, always a Marine!

The love and appreciation for the people I trained, served, and worked with side by side has never faltered. That’s why I am so excited to offer Pretty Muscles to the thousands of American men and women who serve, and the families that support them.


Let’s get fit, strong, and healthy together!

Meet Your Coach

I joined the Marine Corps when I was 20, serving nine years, including two tours in Iraq. During my time in the Marines, I made history when I was appointed to lead the first female platoon and the first to be attached to the infantry in a war zone.


After leaving the Marines, I embarked on a fitness career, cleaning houses while building my client base. I credit my time in the Marines for teaching me hard work, grit, and pushing through. My career grew successful as a trainer in Nashville, and I earned the title of “Trainer to the Stars,” with a client list ranging from Kasey Musgraves, Maren Morris, and many more.
