OCB Pro General Guidelines

OCB Pro Eligibility

Competitors are required to hold current OCB Pro memberships at the time of competing in any OCB Pro events. Competitors cannot have used any substance on the OCB banned list during the duration periods specified on the list.

Competitors must meet one of the following conditions in order to be eligible for OCB Pro contests:

  1. Have won a pro-qualifying placement at an OCB amateur show (see full details).
  2. Have placed first in their class at any natural organization’s pro show.
  3. Have won a pro-qualifying placement with a natural organization other than OCB where there were at least the number of competitors specified below in their division:
    • Men’s Bodybuilding Open: 9
    • Men’s Bodybuilding Age 40+: 5
    • Men’s Physique Open: 9
    • Men’s Physique Age 40+: 5
    • Women’s Physique Open: 5
    • Women’s Physique Age 40+: 5
    • Figure Open: 9
    • Figure Age 40+: 5
    • Bikini Open: 9
    • Bikini Age 40+: 5

Competitors who won a pro-qualifying placement in a Masters Age 40+ division are eligible only for OCB Pro Masters Age 40+ divisions. Competitors over the age of 40 who won a pro-qualifying placement in an Open division are considered eligible for both OCB Open and OCB Masters Age 40+ pro divisions.

Competitors who qualify as OCB Pros for any category are considered eligible for all OCB Pro categories of their gender. Competitors may not compete in more than one category at any given OCB Pro show though. After competitors compete in an OCB Pro category, they are no longer considered eligible for that category in OCB amateur contests.

Competitors are not required to compete within a certain time frame in order to retain eligibility.

OCB Pro Cash Prizes

The minimum cash payouts at OCB Pro contests are $1,000 for 1st, $600 for 2nd, $400 for 3rd. Some shows may award higher amounts. Check a specific show's details for amounts pertaining to it.

Advertised cash prizes are guaranteed. The advertised amounts are not altered based on number of registrations or any other factors.

OCB Pro Yorton Cup World Championships

The Yorton Cup is OCB's top pro title. It awards $3,000 for first place, $2,000 for second, and $1,000 for third for every class (totaled $56,000 awarded at 2017 show). Qualifying for the event at another OCB Pro show is not required for 2018.

Drug Testing

All participants are required to pass polygraph screenings prior to competitions (polygraph test results from OCB and other natural federations' shows can be honored for OCB shows held within three weeks from the contest where testing took place. For federations other than OCB, the polygraph examiner who conducted the testing must send verification to OCB, or the examiner's name and contact information must be supplied to OCB in order for results to be honored). In addition to polygraph testing, the top three placement winners in classes must pass a urine test.

Polygraph screenings are used since events are 7 years drug-free for most substances. Many anabolic steroids and other banned substances are no longer detectable in urine within a couple of months of last use - some even less than that - and growth hormone use cannot be detected with urine testing. Note: Approximately half who don’t pass the polygraph are bikini competitors. Banned substance use is not always about achieving greater muscle size... certain banned substances can yield an unfair advantage in getting leaner and shapelier.

Pro Categories & Divisions

OCB Pro categories offered are: Bikini, Figure, Men’s Bodybuilding, and Men’s & Women’s Physique (Men’s Classic Physique is planned for the future). Divisions offered are Open and Masters Age 40+. Check a specific event's details to see which of the categories and divisions are offered at the particular event.


When divisions have more than one class, the majority of OCB events divide groups into as equal as possible parts by height based on total number of entries in a division. Formation of classes within divisions at a show is at a promoter's discretion though, and could sometimes be done by using specified height or weight ranges. Check a specific event's details to see which method will be used for a particular event.


Each judge takes all criteria for a category into account and assigns one overall score for each contestant in the form of rank during the group comparison rounds. A highest and lowest rank for each competitor is dropped as a safeguard against human error and/or bias, whether intentional or on a subconscious level. The remaining judges' placements are summed, and the competitor with the lowest sum total receives 1st place in the class. Second lowest sum receives 2nd place, and so on. In cases of ties, competitors ranked higher by the majority of all judges are awarded the higher placements (see video example). In cases of three-way ties, the head judge's scores are referenced to determine tie-breaking placements. Individual presentations are not factored into scoring but do count toward consideration for Best Poser awards when offered.
