In Episode 181 of the Fit Mother Project Podcast, Dr. Anthony Balduzzi kicks off a powerful new solo teaching series with a message that cuts straight to the core: after 40, muscle is not optional. It is the master regulator of aging, metabolism, hormones, and long-term independence – even for women.
Dr. Balduzzi explains why aging is not about birthdays, but about muscle loss — and how strength training directly improves fat loss, insulin sensitivity, mitochondrial health, joint integrity, nervous system resilience, and even brain function. This episode reframes exercise from a “nice to have” into a foundational survival skill for modern life.
If you want to feel stronger, leaner, more energized, and mentally sharp in 2026 and beyond, this episode will permanently change how you think about training — and why building muscle may be the single most important health decision you make this year.
