Why walking alone won't preserve muscle

Can strength training, sprinting, and nutrition truly transform women’s hormones, metabolism, and longevity?

In this episode, Dr. Stephanie Estima — chiropractor, women’s health expert, and founder of The Estima Method — breaks down the science of female physiology, muscle, and midlife health.

We cover why walking isn’t enough, how hormones shape muscle and bone, and why protein and strength training are essential “medicine” for women over 35. Expect myth-busting, practical tools, and empowering insights to help you train and live in sync with your biology.

About Dr. Stephanie Estima:

Dr. Estima began her career in chiropractic care, where she developed a deep interest in neuroscience, biomechanics, and the body’s connection between movement and the brain. After noticing how differently men and women respond to the same health strategies, she became passionate about helping women navigate hormones, metabolism, and midlife health.
