Men's Classes
-
Physique
Men’s Physique is for athletes with an athletic, well-proportioned upper body, a small waist, and an overall “beach fit” look—without the extreme size, hardness, or mass of bodybuilding.
Best suited for: athletic physiques with strong proportions and a pronounced V-taper.
Not suitable for: heavily muscled or extremely conditioned bodybuilding physiques. -
Classic
Men’s Classic is for athletes who display a balanced, aesthetic bodybuilding physique with emphasis on shape, symmetry, and proportion, rather than maximum muscle mass.
The class rewards a classic bodybuilding look, combining muscular development with clean lines and controlled conditioning, within height-to-weight limits. -
Open 1,2,3,4
These are traditional open bodybuilding categories divided by height only. There are no weight limits. Athletes are grouped solely by height to ensure fair comparison on stage.
Juniors & Masters
-
Junior
This class is for younger competitors who are under the specified age limit on the day of the show and are developing their physique within a competitive bodybuilding environment.
The class is designed to encourage progression, good structure, and balanced development, while recognising that Junior athletes are still in the earlier stages of their competitive careers. -
Masters
These are age-based categories designed for experienced competitors aged 40 and above, grouped by age to ensure fair comparison on stage.
