You’re Not Over the Hill, You’re in the Valley: Why Exercise Must Increase With Age

Katy offers an aging reframe: in middle age, you are not “over the hill”—you are actually at the bottom of a valley, and staying strong and healthy means choosing to go uphill on purpose. Katy and Jeannette unpack the difference between chronological age and biological aging, why modern life may be speeding up the aging process, and how movement and exercise positively influence the cellular “hallmarks of aging.” They explore why exercise needs to increase with age (even when life gets busier and energy feels lower), and how reframing discomfort can make consistency possible—so you can extend not just your lifespan, but your healthspan, too.

Katy also speaks with Pack Matthews of Ikaria Design (creator of the Soul Seat) about “active sitting” and why our rest positions matter as we age. Pack shares his personal origin story—using floor-sitting and dynamic postures to counter arthritis. They also preview the upcoming Soul Seat Mini for the smaller people in your life and explore its role in dynamic classrooms.
