Your First Bodybuilding Competition: A Beginner's Guide, Start to Finish

A first show is mostly unknowns: which federation, which division, how long to diet, what happens backstage. None of it is hard once you have seen it once. This guide is the walkthrough I wish every first-time athlete had, written by someone who has competed and coached athletes to natural stages.

Step 1: Decide if you are ready

Being ready to compete means having enough muscle that getting lean will show it. Diet an under-muscled physique to stage leanness and it just looks small. Two honest checks:

• Look at photos of athletes placing well in your division at a local show. Are you close in muscle, if not in leanness?
• Can you live with months of tracked food, scheduled training and posing practice?

If the answer is "not yet", the next step is an off season, not a prep.

Step 2: Choose a federation

Federations differ in testing, divisions, rules and where their shows are. If you are natural, compete in a drug-tested federation, so you are judged against other natural athletes. See what natural bodybuilding means and the federations compared.

Step 3: Choose a division and a class

The division is the type of physique: bodybuilding, classic physique, men's physique, bikini, figure, wellness or women's physique. Pick the one that rewards the physique you have, not the one you want in five years:

• Men's physique for a strong upper body and V-taper, legs less developed.
• Classic physique for a balanced physique with legs, built for symmetry over size.
• Bikini for a toned, lightly muscled hourglass.
• Figure for more shoulder and back development.

Then the class. Most federations run classes such as novice, open and masters. A first-timer usually belongs in a novice or debut class. Our divisions guide explains them.

Step 4: Choose a show far enough away

The OCB's getting started guide puts a typical contest prep at 8 to 32 weeks (OCB getting started). Work out your own number: estimate the fat you need to lose, and divide by a rate of 0.5 to 1% of bodyweight a week, the rate the research on natural competitors recommends (Helms et al., 2014). Then add a month of buffer and pick a show at least that far away.

The OCB also suggests attending a show before you compete, to see how your category is judged. It is good advice in any federation.

Step 5: Run the prep

The diet

A slow, steady deficit with high protein. Our contest prep diet guide has the numbers and a worked example.

Training

Keep lifting heavy enough to keep muscle. Prep is not the time to change your whole program. Cardio is a tool for the deficit, added as needed.

Posing

Start in week one. Judges only see your physique through your posing, and it takes months to look comfortable. See bodybuilding poses.

Weekly check-ins

Weight averages, measurements, photos, posing video and how you feel. The free contest prep check-in template covers them.

Step 6: Register and get tested

In the OCB, for example, the path is (OCB getting started):

• Take out an amateur membership.
• Choose a show from the event list, then register and pay the entry fees, including any crossovers into a second class.
• Take the drug screening before the event.
• Attend check-in to collect your number and book tanning, hair and make-up or photos if you want them.

Other federations follow a similar pattern; check registration deadlines on the show's page.

Step 7: The last week

For a first show, the best peak week is a quiet one: get lean early and change as little as possible at the end. Avoid extreme water and sodium changes, which a 2021 research review found no evidence are effective or safe. Read peak week in bodybuilding and use the free peak week tracker.

Step 8: Show day

Most shows run prejudging, where most of the judging happens, and later a finals session with individual routines and awards. Expect a long day with a lot of waiting. Have the day's food written down.

Show day checklist

• Suit or trunks (and a spare), plus suit glue if your division uses it
• Heels for bikini, figure and wellness
• Membership card, registration confirmation and ID
• The day's planned food and water, in a cooler
• A dark robe or loose dark clothes and sandals to protect the tan
• Posing oil or glaze, if your federation allows it
• Resistance band or light weights for pumping up, if allowed backstage
• Your posing music, saved in the format the promoter asks for
• Phone, charger and something to pass the time

Step 9: After the show

The hardest part of a first show is often the week after. Appetite returns, weight comes back fast, and many athletes feel flat. Plan the reverse diet before the show, and ask the judges for feedback if the federation offers it. It is the best guide to your next off season.

For coaches taking on first-timers

First-time competitors ask a lot of questions and need a lot of reassurance. A coach who answers in one place, with the plan and the last check-in on screen, saves both sides hours. CoachPilot keeps the meal plan, check-ins and messages together for each athlete. See contest prep coaching software.

The short version

Make sure there is enough muscle to show. Pick a tested federation if you are natural, a division that suits your physique and a novice class. Work out your prep length from a slow rate of loss and pick a show further away than that. Start posing in week one, register early, keep the last week quiet and plan what happens after.
