Rick Deltoid (voiced by Stan Freberg) is a television fitness instructor, given nicknames such as "The Pharaoh of Fitness" and "The Sultan of Sit-ups".
Deltoid formerly had a show on WBOR. Jon Arbuckle was a devout follower of him, much to the dismay of Garfield, who figured he would "never get a decent meal as long as Jon listens to Bonehead the Barbarian". He also has a gym for working out.
- His surname "Deltoid" is named after the Deltoid muscle.
