As physical culture became increasingly popular and profitable, there arose intense national and then international competition amongst the founders and/or promoters of various systems. This rivalry became informally known as "the
Battle of the Systems". Both public gyms and educational institutions tended to take an
eclectic approach, whereas private physical culture
clubs and organizations often promoted particular exercise systems initially based on ethnocentric and cultural links. Early private establishments were based on ethnic and cultural affiliation, such as the Turners and Sokol movements. These ethnocentric systems in America were centered on integration, and later stood apart from their origin countries, having very little contact with them by the time
World War I emerged. Later outfits were based on preference to what each system offered as a matter of practicality, with some systems retaining in their names historical references to their geographic origin. The
German Turnverein movement promoted a system of what became known as "heavy
gymnastics", meaning strenuous exercises performed with the use of elaborate equipment, such as
pommel horses,
parallel bars, and
climbing structures. The Turnverein
philosophy combined physical training with
intellectual pursuits and with a strong emphasis on German culture. Numerous events in modern competitive gymnastics originated in or were popularized by the Turnverein system. The
Czech Sokol movement for physical culture was largely inspired by Turnverein. By contrast with the German and Czech systems, the "Swedish System" founded by
Pehr Henrik Ling promoted "light gymnastics", employing little, if any apparatus and focusing on
calisthenics,
breathing and
stretching exercises as well as
massage. At the turn of the 20th century, bodybuilder and showman
Eugen Sandow's system, based upon
weight lifting, enjoyed considerable international popularity, while
Edmond Desbonnet and
George Hebert popularized their systems within France and French-speaking countries.
Bernarr Macfadden's system became especially popular within the United States, via the promotion carried out through his publishing empire, particularly its flagship magazine titled "Physical Culture." Other notable advocates of physical culture include
Jørgen Peter Müller and
Mary Bagot Stack. ==Australia==
