I first started using your methods in late 2010. First DEFL, then FTFL. Throughout both those programs, these 5 exercises are featured. I have gone from stooped over, rounded shoulders and a core that couldn’t stay straight, to perfect posture and a body I am proud to have! I’m a 51-year-old female and now I can hold my own on your advanced workouts and I still can barely believe it! To all you out there – do what this man says and your body will transform. Thank you Dr. K, from the bottom of my heart! With deep gratitude and affection,
