The Younger Body & Mind platform isn’t built on theory.
It’s built on decades of real training, real discipline, and real results.
Behind it are two dedicated practitioners and teachers, Billy and Melissa, who have spent years refining what actually works when it comes to strength, movement, and long-term health.
Different paths. Same mission:
Help you build a stronger body, a clearer mind, and a life that doesn’t slow down with age.
Billy Greer
50+ Years of Experience. Built on What Works.
Billy has spent a lifetime training, teaching, and refining martial arts. With roots going back to 1973, his approach is grounded in discipline, consistency, and proven methods that build real strength and long-term health.
As an inheritor in two traditional lineages, he carries forward systems that have been tested across generations, and teaches them in a way that’s practical, clear, and effective.
Melissa Wittke
Proof It’s Never Too Late to Get Strong.
Melissa’s journey started later, but that’s exactly what makes it powerful. Beginning in 2012, she earned her Black Sash at 53 and went on to become a 13th generation disciple in Chen Style TaiJi.
As an author and advocate for reinvention, she helps others break past limits, build confidence, and step into a stronger version of themselves, at any age.
