Bodybuilders are judged on the OVERALL QUALITY of their muscular development.

Mass: The perception of muscular size has been the foundation for bodybuilding since the beginning of the sport. Yet, mass is only a merit when accompanied by the remaining qualities.


Definition: Indicates the degree of muscularity brought about by the absence of subcutaneous body fat. Defined muscularity is necessary to fully display the development of the physique. Definition is only of value when it allows massively developed muscles to be displayed.

Proportion: Implies an even balance of muscular development in comparison to each muscle group. Theoretically, a "strong body part" can be just as detrimental as a "weak body part". Bodybuilders must strive for equal development between all muscle groups. Symmetry A misnomer, is commonly used to depict "proportion" or expressed to indicate an aesthetic quality throughout the physique. Although, in its strictest definition, symmetry denotes equal development of muscularity on both right and left sides of the physique.

Stage Presence Includes posing performance and other factors influencing general appearance such as skin tone, grooming, charisma, and poise. Effective stage presentation is essential to display the physique to its maximum potential.

Attire: Athletes are required to wear suitably fitting trunks no restriction on colour or material / shorts or underwear are not permitted.

Novice Class:


Novices must not have previously been placed in the top 3 in a NABBA Area novice

contest, or have won ANY OPEN contest.

Men's Classic Bodybuilding: 



Criteria as above, but in addition must meet the height to weight ratio requirement:

(Height in cm - 100) + 8 = max kg

Example: 170cm height athlete would be 170 - 100 = 70 + 8 = 78 max kg

Therefore, 78kg will be their maximum competition weight.

The Britain Finals and Universe competitions could have 2 height classes depending on numbers entering this category:

Up to and including 172cm  to use their height  - 100  + 8

Over 172cm (Introduce January 2020)

to  use their height - 100 + 10

All Men's Bodybuilding Classes will follow the same structure:


Round 1 Quarter Turns

Competitors will line up at the posing line with a front stance. The judges will instruct competitors with "Quarter Turn To The Right" until they are facing the judges once more. The athletes may be split and/or rearranged to allow accurate assessment by all judges. Competitors will hold each stance to demonstrate balance, symmetry and proportion along with the mass and condition of their physiques. This important round will have significance when the judges are determining the initial "call-outs" for round 3.

Round 2 Routine

Each competitor will then be required to do an individual posing routine. This is the opportunity to display their physiques to the judges without distraction. It is advised that athletes present themselves with confidence and control of their physique. Displaying each muscle group to the best of their ability. Athletes can use mandatory and non-mandatory poses of their choice.


Routines to be a minimum of 45 seconds, (Area Competitions can go up to 60 seconds max. dependant on amount of competitors in each class,) However you must check with your Area Rep who will inform you of the times for their show.

45 seconds max is designated time for the Britain Finals, England and Universe Competitions.

Round 3 Comparisons

Competitors will be called back on to stage. Competitor numbers will be called requesting them to come front / centre stage in small groups of 4 - 6, known as the "call-outs".


The judges will request the following poses.

1. Abs and Thighs

2. Lat Spread

3. Front Double Bicep

4. Side Chest (any side)

5. Side Tricep (any side)

Turn to face the rear

6. Rear Lat Spread showing Hamstring and Calf

7. Rear Double Bicep

Athletes who are not in the line-up are asked to adopt the "front stance" with no posing.
