Physical training instructor

Physical training instructor (PTI) is a term used primarily in the British Armed Forces and British police, as well as some other Commonwealth countries, for an instructor in physical fitness.

United Kingdom

In the British Army, the specialist instructors of the Royal Army Physical Training Corps oversee physical training and manage military gymnasiums and are attached to individual units. They are assisted by All Arm Physical Training Instructors (AAPTIs), previously known as Assistant Physical Training Instructors (APTIs), who are qualified, but are not specialists, have other jobs within the unit, and are not drawn from the RAPTC. The PTI badge consists of crossed swords.

Physical training instructors in the Royal Navy are officially titled Physical Trainers and are known as "club swingers" or "clubs" from the crossed clubs they wear as a rate badge. In the Royal Air Force, the PTI badge consists of crossed swords with an eagle in the centre.

New Zealand

The New Zealand Defence Force also employs Physical Training Instructors who bear the same symbols as their British counterparts. The New Zealand Army Physical Training Corps wear the crossed swords, Royal New Zealand Navy PTIs wear the crossed clubs, and Royal New Zealand Air Force PTIs wear the clubs and arms.

In March 2016, all Navy, Army and Air Force Physical Training Instructors were amalgamated into the new NZDF tri-service unit known as the Joint Operational Health Group.

NZDF PTIs use the motto Mens Sana In Corpore Sano, which roughly translates as "a healthy mind in a healthy body".
