In this special solo episode, Barbara launches The Journey to 70, a yearlong series leading up to her 70th birthday. Just as she did at 50, she’s reassessing what truly matters for staying strong, mobile, and joyful in the decade ahead. 

Barbara previews the first expert in the series — Dr. Jocelyn Wittstein, orthopedic surgeon and sports medicine specialist at Duke University — who will guide her through the essentials of bone and joint health. 

Today, Barbara shares one powerful change she’s already made: Japanese Interval Walking. After a knee injury sidelined her from running, this simple, science-backed method helped her rebuild strength, energy, and confidence. She explains why it works and how you can start using it right away.

• The Journey to 70 mini-series begins 
• Why interval walking is ideal for women over 50 
• A joint-friendly way to boost fitness, strength, and energy
