About the International Streetlifting Federation
International Streetlifting Federation (ISF) develops Streetlifting and Weighted Calisthenics as transparent international strength-sport disciplines. We connect athletes, officials, organizers and national federations through one technical framework so results, records and titles remain comparable beyond a single event.

What ISF maintains
ISF maintains technical rules, competition formats and judging interpretations for Streetlifting and Weighted Calisthenics. This framework does not replace national law or national federation requirements.
Why a federation matters
Unified rules, categories, protocol standards and appeal routes protect the long-term value of athlete results, records and titles across different competitions and countries.
Competition integrity
Sanctioned competitions work within clear requirements for equipment, officials, athlete admission, safety, protocols and publication of verified results.
Officials and education
Referee and secretary certification connects rule knowledge, practical judging and accurate protocol work so competition decisions can be understood and checked.
Results, records and standards
ISF develops an open results workflow for competition protocols, record verification, standards and team scoring instead of isolated event rankings.
National development
National Federations and Official Representatives build local calendars, competition teams and athlete pathways while working within the international ISF framework.
