Women’s Bodybuilding Open (Ms Olympia): Rules, Criteria — A Reference
Last updated: 17 April 2026.
What Women’s Bodybuilding Open is
The apex division of women’s bodybuilding since 1980. Ms Olympia is the annual world championship. This is the division where athletes like Cory Everson, Lenda Murray, Iris Kyle, and Andrea Shaw built their legacies.
The division was discontinued by the IFBB Pro League 2015–2019 and replaced in practice by the Rising Phoenix World Championships (Wings of Strength) during that window. Ms Olympia was reinstated 2020 under Wings of Strength promotion. Andrea Shaw has won every Ms Olympia since 2020 (six consecutive as of 2025).
Era note: Per Dossier #2, SteelQueens treats Rising Phoenix 2015–2019 as apex-event-equivalent for Iron Score weighting. This is an editorial decision (Position C) documented on /methodology/.
Scoring axes
- Mass and density — the defining axis (vs Physique)
- Muscle separation and striation — back, shoulders, hamstrings
- Conditioning — low body fat, hardness, dryness
- Symmetry and proportion — the classical criterion
- Muscle group balance — no visible lagging part
- Posing execution — mandatory pose precision and stage presence
