Michael Federer is the son of William & Susie Federer. Also, he is a trainer and a YMCA Director, and a dedicated Christian. Michael had a couple of good personal testimonies coming from his work with men as a trainer, and how athletics trains the body, but also has a salutary effect on the soul, and builds Christian character. One of the highlights is the athletic and military metaphors in the Pauline writings. As a side note, there is a bilingual, Mandarin/English congregation in Edinburgh, Scotland that advertises free Martial Arts Training and introduces people to Christ through physical training.
