What if the secret to longevity, fat loss, and hormonal balance wasn’t a punishing workout—but a powerful, restorative walk? In today’s Bite Size episode, Angela shares a clip from her conversation with health renegade Mark Sisson, where they bust the myth that running is the pinnacle of fitness. Mark, once one of the top marathoners in the U.S., reveals why he hasn’t run a mile in 30 years and how walking became the foundation of his health philosophy.

From cortisol-driven fat gain to the myths propagated by the shoe industry, this eye-opening episode will make you rethink your relationship with movement. If you're a woman in midlife craving more energy, fewer injuries, and a smarter approach to fitness—this one's for you. Tune in to discover why you were truly Born to Walk.

KEY TAKEAWAYS:

Walking Reduces Inflammation: One of the most accessible ways to lower cortisol and support blood sugar.
Running Can Be Catabolic: Chronic running often leads to muscle breakdown and fat storage due to elevated cortisol.
Fat-Burning Secret: Walking helps you burn fat instead of glycogen, supporting better body composition.
Rethink Endorphins: Many people don’t love running—they love the feeling after and the label it gives them.
Sprinting + Lifting = Longevity: A minimalist combo of walking, sprinting once a week, and strength training wins for healthspan.
