Launching a career in instructing and fitness at the age of 16 as the youngest full instructor of Shotokan karate in the US at the time, Jeff Bradt has since acheived the rank of "sandan" (third-degree black belt) in karate, worked as a personal trainer, life coach and trained facilitator in the Sedona Method. Now as the creator of the Fit@50! Fitness Video Series, Fit@50! Success Strategies and the Fit@50! Fitness System, he is helping middle-aged people increase their level of fitness so that they can lead healthier and happier lives.
