the importance of both injury prevention and using exercise science to train smarter and improve police
performance. Brian has trained with PKCO owner James Di Naso for several years and has assisted him in
coaching the youth members of the Olympic weightlifting club that James sponsors, as well as numerous
officers (both male and female) with their own fitness programs. He is currently pursuing certification from

career to develop law enforcement specific training programs. Brian’s influence led to the development of
James’s first police fitness course, which eventually became the PKCO Tactical Police Agility Practitioner
course several years later.
