First-timer means you have never entered a bodybuilding competition before in any federation. You may be a First Timer in multiple divisions, provided you have never competed before for any federation.
Age groups include 30+, 40+, 50+, 60+ and 70+ classes in several divisions.
All age groups are not guaranteed at every competition, and ICN reserves the right to combine age groups. You must be of the age or older to enter an age group class; for example, you must be 30 years or older to enter 30+.
U21s, you must be 21 years or younger to enter this class.
Open is the class all competitors should strive to reach. This is the highest level of any amateur division. If you have competed regularly as an Open competitor in a division before, in any federation, we suggest you enter Open.
