This week we sat down with Ben Musholt, a physical therapist by trade, parkour athlete when not working, former America Ninja Warrior participant, and author of Parkour Strength Training: Overcome Obstacles for Fun and Fitness and Mad Skills Exercise Encyclopedia: The World's Largest Illustrated Exercise Encyclopedia.

In this episode we tackle a lot, including:

• Ben's background as a physical therapist and his childhood as a "constant mover"
• Why we should all continue to "play" as we age
• Ben's thoughts on why we as a society "workout" inside now, instead of "play" outside
• Ben's definition of parkour and his perspective on the role of functional movement across the lifespan
• Twitter follower questions, including Ben's 5 favorite bodyweight exercises, how to treat hypo- and hyper-mobile patients, and how to get clients with chronic pain past their fear of movement
• Ben's advice for his younger self and for people starting out in their careers
