As a child, Little was abandoned by his father, and raised by his mother in Fremont, Ohio. As an adult, he moved to Tampa, Florida to advance his personal fitness career. Little has two children from an early relationship, daughter Tara (born ca. 1987) and son Trent (born ca. 1988). Little is now married to fitness model Melissa Hall, who has been seen on several of his home shopping channel appearances.

Little is an avid collector of antiques, classic cars, and obscure species of livestock; he owns eight of the latter.
