Marshall Roy is a personal trainer, accomplished powerlifter, kickboxing black belt, published writer, and owner of RISE gym in King of Prussia, PA. He earned his personal training certification from the National Academy of Sports Medicine (NASM) and is an SFG Level II kettlebell instructor, Precision Nutrition nutrition coach (Pn1), and certified practitioner of the Functional Movement Screen (FMS).

Marshall led his first group exercise class when he was four years old; the participants were his three siblings and grandfather. (There is definitely not an old VHS of this event buried somewhere in the Roy home.)
