John McCallum, both literally and figuratively, shaped an entire generation of would-be musclemen: His original articles have become classics and inspired many of today’s top muscle writers. To this day, many feel that these articles established the highest standard in the field.
“John McCallum was my monthly reminder to be all that weight training would allow me to be... Without any doubt, he was my earliest and strongest influence and one that has endured.”
