What is APF?
APF stands for "Asia Physique Federation" and is one of the rapidly growing fitness competition organizations in Japan.
Characteristics of APF Competitions
The biggest characteristic of APF competitions is their judging criteria, which emphasize "stage presence" and "physical beauty."
Instead of only evaluating muscle mass, overall balance, style, and posing are comprehensively judged, making it a fitness competition with a relatively high level of entertainment value.
Additionally, with strong show elements like lighting and stage direction, it is popular as a competition that audiences can also enjoy.
APF offers class divisions to make it easier for beginners to participate, with categories for first-time competitors and height-based classes.
Therefore, it attracts a wide range of participants, from "first-time fitness competitors" to "top-level athletes."
Furthermore, competitions are held across the country, and the ability to compete in contests throughout the year is another attractive point.
Differences from Other Fitness Competitions
There are various organizations for fitness competitions, and their judging criteria and competition atmosphere differ.
The differences between APF and other major fitness organizations in Japan are summarized in the table below.
| Organization | Characteristics | Judging Tendency |

| SSA | Popular Japanese organization | Well-balanced physique |
| FWJ | Collaborates with international organizations | Muscle mass and conditioning |
| JBBF | Japan Bodybuilding Federation | Emphasizes muscle mass and athleticism |
Compared to other organizations, APF tends to emphasize "body silhouette" and "stage presentation," making it a competition that values style.
What is APF Physique? Explanation of the Competition Content
APF Physique is a competition category where contestants wear surf shorts and compete on the balance and beauty of their physique. Key judging points include a "V-tapered body," "narrow waist," and "wide shoulders."

August-October: Large-scale competitions held nationwide

November: End-of-season competitions

Which APF Competition Should You Enter? Competition Level List
According to the official APF (Asia Physique Federation) rules, there is no level differentiation for the competitions themselves, such as "FIRST IMPACT is only for beginners" or "TOKYO competition is for advanced athletes."
In APF, levels are categorized not by the competition itself, but by the "category (class) you enter" within it.
-
First Timer (for those competing for the very first time only)
-
Newcomer / Novice (introductory to intermediate class)
-
Open (advanced/elite class, open to anyone)
In other words, if an APF competition has a "First Timer" class, it's perfectly fine for beginners to participate, as everyone else will also be beginners.
How to Enter an APF Competition
To enter an APF competition, you need to register on the official website in advance.
How to Enter an APF Competition
STEP 1: Choose the competition you want to enter
First, decide which competition you will enter.
-
Check the Contest page on the APF official website
-
Check dates, locations, and categories
-
Choose a competition considering your weight loss schedule and travel distance
Competitions are held across Japan from spring to autumn, so it is important to choose a competition where your condition will be at its peak.
STEP 2: Create an APF Card (Membership Registration)
To enter an APF competition, you need to register for an APF Card.
-
Register as a member on the APF official website
-
A "My Page" will be created after registration
-
Registration fee: 10,000 yen
-
Validity period: January 1 to December 31
Since you cannot enter a competition without this APF Card, you must register for it first.

STEP 3: Enter the competition
Once you have created your APF Card, the next step is to enter the competition.
-
Log in to your APF My Page
-
Select the competition you wish to enter
-
Click the "Apply" button
-
Select the entry category
-
Fill in the required information and apply
Once the application is complete, if the status on your My Page changes to "Applied," your entry is confirmed.


APF Competition Entry Fees
To enter an APF competition, several preparation costs are required. The main costs include "competition entry fees," "body coloring fees," and "competition attire (surf shorts)."
Below is an estimate of the main costs required to enter an APF competition.
| Cost Item | Average Price |
|---|---|
| APF Card registration fee (mandatory) | 10,000 yen |
| Competition entry fee (mandatory) | Approx. 8,000-15,000 yen |
| Backstage pass (optional) | 13,000 yen |
| Coloring (mandatory: designated provider) | Approx. 10,000-20,000 yen |
| Surf shorts (mandatory) | Approx. 8,000-20,000 yen |
For Men's Physique, wearing surf shorts according to competition regulations is mandatory, so first-time competitors will also need to factor in the cost of purchasing surf shorts.
A backstage pass is an admission ticket for support staff, such as trainers or friends, to enter the dressing room. Also, many competitions prohibit coloring by providers other than those designated.
In total, the preparation cost for first-time APF competitors is typically around 30,000 to 50,000 yen. Depending on the competition, travel and accommodation expenses may also be incurred, so it's best to prepare with ample time.
Preparation for APF Competitions
To participate in an APF competition, it's not just about entry; preparation for the competition day is also necessary.
In fitness competitions, not only physical conditioning but also posing and stage presentation are important evaluation points, so it is crucial to prepare thoroughly in advance.
Conditioning
Weight Loss
In fitness competitions, a condition where muscle lines and body silhouette are clearly visible is required.
Generally, weight loss starts several months before the competition, and conditioning is adjusted through a combination of training and diet management.
It is important to reduce body fat while maintaining as much muscle mass as possible, so it is essential to proceed with a planned approach rather than drastic weight loss.
Posing Practice
In APF physique competitions, athletes perform poses on stage to showcase their body balance and silhouette. Therefore, posing practice is necessary before the competition.
In competitions, specific poses are often set for each category, and "callout judging" is performed where multiple athletes line up for comparison.
The appearance of the body can change significantly depending on the completeness of the posing, so it is not uncommon for athletes to practice in front of a mirror or receive posing instruction.
Items needed on stage
Surf Shorts
In the Men's Physique category, surf shorts are worn on stage. Surf shorts are not just an outfit; they are a crucial item for enhancing the body's silhouette.
For example, depending on the design and color, the waist might appear slimmer or the length of the legs emphasized, meaning the impression on stage can change significantly based on the chosen surf shorts.
Additionally, APF competitions have regulations regarding the length and design of surf shorts, so it is necessary to choose surf shorts that comply with these rules.
Therefore, many athletes competing in APF Physique use surf shorts specifically designed for physique competitions. In men's physique, the choice of surf shorts can change how the waist appears slim or legs appear long, making them a very important item among competitors.
Coloring
In fitness competitions, coloring is done to clearly show the muscle definition. Coloring enhances the cuts of the muscles under stage lighting, emphasizing the body's three-dimensionality.
In APF competitions, it is often the case that a specific coloring service provider is designated depending on the venue, so it is important to check the competition guidelines in advance.
Official Rules for Physique Shorts in APF Competitions
Below are the official APF rules for physique surf shorts:
- Swimsuit check at check-in (swimsuits violating rules will be penalized)
- Regulated shorts: Must be off-the-shelf surf shorts / No logos other than those on off-the-shelf products.
- No alterations (waist adjustment is allowed).

APF Officially Recommended Brand ①: ALL OUT
ALL OUT is a Japanese fitness brand that is currently gaining the most enthusiastic support from physique athletes in Japan, and is officially recommended by APF.
There are also models personally supervised by Mr. Adachi, CEO of APF, making them perfect for APF competitions.
Furthermore, it completely resolves the unique problems Japanese people face with overseas brands, such as "the length is too long when adjusted to the waist" or "excess fabric at the hem makes the legs look thin," through a rich size lineup and meticulous three-dimensional cutting.
No alterations are needed, and you get a tapered silhouette that looks great on stage the moment you buy it.

APF Officially Recommended Brand ②: VEATM
Another brand that exudes an overwhelming presence on the APF stage is VEATM, a domestic fitness apparel brand that has seen explosive popularity in recent years.
VEATM's surf shorts are characterized by their minimalist and stylish design, as well as meticulously calculated stretch fabric that causes no stress during intense posing.
The silhouette itself is designed to be very tight and beautiful from the start, so there is no excess fabric on stage even with off-the-shelf products.

How to Choose Surf Shorts for APF Physique Competitions
In physique, choosing surf shorts isn't about "just wearing whatever."
Even a physique that has been honed to its absolute limit can look dramatically different depending on the fit and design of the shorts.
Here, we will explain the "key points for choosing the perfect size" based on international rules and the latest trends, ensuring you won't make a mistake.
【Important】Choose a brand officially recommended by APF
When choosing physique surf shorts, it is most reliable to choose a brand recommended by the competition organization you are entering.
Different organizations prefer different designs and silhouettes, so in actual competitions, there are "brands commonly seen in that organization."
As mentioned earlier, VEATM and ALL OUT are frequently worn by athletes in APF (Asia Physique Federation) competitions and are officially recommended.
ALL OUT is recommended by multiple organizations and is a standard choice for stage shorts.
(ZENIX, a noteworthy new organization in 2026, also recommends ALL OUT.)
Directly Impacts Judging! The Golden Ratio for Length is "5-10cm Above the Knee"
The "length" of surf shorts is a point that is very strictly observed in physique judging. The official rules of the IFBB PRO (International Federation of Bodybuilding and Fitness), the world's most authoritative body, explicitly state the following:
"They must be just above the knee in length." (In judging and finals, the length of the surf shorts must be just above the knee)
Source: https://www.ifbbpro.com/rules/
While the rules on length were ambiguous when the category was first established, they are now strictly enforced. This means that both too long and too short can be subject to "deductions."
- Too long: The lower cuts of the quadriceps are hidden, making the entire leg appear shorter.
- Too short: Gives too casual an impression, diminishing the sophisticated atmosphere unique to physique competitions.
A length that clearly exposes the kneecap (patella) and falls approximately "5cm to 10cm above the knee" is the golden ratio that makes the legs appear longest and most powerful.
Aim for a snug fit at the waist
Equally important as length in size selection is the fit around the waist.
Looking at how top pros dress now, it is common to see waistbands tied with black-colored cords.
This creates a cinched effect on the abdomen, producing a more refined V-shape.
When choosing your waist size, pay attention to the following points:
- Too loose (NG): It will shift during intense posing, making the lower abdomen look bad.
- Too tight (NG): Tying it too tightly will put pressure on your abdomen, making your stomach appear to stick out.
If you are purchasing an overseas brand where trying it on in-store is difficult, thoroughly check reviews and size feedback from other athletes, aiming for a "just-fit to slightly tight" size.
Choosing Colors and Designs Based on Objective Evaluation
Beyond sizing, there are clear "criteria for winning" when it comes to choosing colors and designs.
Beginners often tend to choose "their favorite colors" or "flashy, detailed, or camouflage patterns," but the judges, not themselves, are doing the judging.
Even if it feels "good" in front of the mirror, the impression will be completely different under intense stage lighting or from the audience's perspective. Always incorporate an "objective third-party perspective" when making the final decision.

What I first noticed when I wore them was the excellent fit and ease of movement! Even when striking poses on stage, the fabric didn't pull, allowing me to naturally show my body lines.
In particular, the waist design visually tightens the waist, giving the impression of an even more emphasized V-shape.
Also, as expected from a model supervised by Mr. Adachi, the CEO of APF, the length and silhouette balance were exquisite! The clean line above the knee made it easy to balance with the upper body, which I felt significantly enhanced my stage presence.
