April Coker | Perimonpause & GLP-1 Strength & Health Coach

I’ve been strength training for over 30 years, not as a trend, but as a constant. That is, until perimenopause hit and my motivation vanished. Suddenly, my body changed, and I found myself wondering, “Why can’t I just get it together? I know exactly what to do!”

I founded Core Theory Fitness ten years ago to teach proper, sustainable strength training and help prevent injury, especially for women often steered toward cardio‑only plans and under‑fueled nutrition. I didn’t realize then how personal that mission would become.

Like many women, I entered perimenopause unprepared. Strength, recovery, and body composition all shifted, and with the rise of GLP‑1 medications, the risk of muscle loss became impossible to ignore. In November 2025, I decided to relaunch Core Theory Fitness with a new location and a sharper focus: Strength Training and Metabolic Health Coaching for women in perimenopause and menopause and individuals using GLP‑1 therapy, to rebuild strength, protect bone health, and maintain vitality.

Muscle isn’t about aesthetics; it’s about independence, stability, and long‑term health. Without intentional strength training, muscle loss accelerates as hormones drop, especially from our late 30s onward. My role is to make sure that doesn’t happen to you.

As an ACE‑certified Personal Trainer and Health Coach, member of The Menopause Society, and a specialist with advanced training in biomechanics and osteoporosis, I design programs that support changing bodies, correct imbalances, and keep you strong for decades to come. I live this journey myself, and I’m here to help you feel strong and capable again. Not like your old self, but your best self now.
