It seems odd to me that hundreds of people each year are trained as personal trainers with certifications in “functional training,” yet I rarely meet someone who can teach what I teach, how I teach it. They don’t really understand the deep core musculature. They don’t really know what stretches or exercises accomplish what gains. They don't really understand the progressions that help clients--who've been in active pain for weeks, months, or decades--get a truly strong core and a pain-free back.
And then it finally dawned on me: It’s my personal experience with back pain that makes my style or method of teaching so effective.
