How to Fill Adult Martial Arts Classes

Your kids' class is packed—30 to 40 students attending consistently. Parents lined up, waiting in the lobby.

Then your evening adult class starts.

An average of six to eight adults show up.

What gives? You have the experience, the instructors, and the space. Why isn't your adult program growing?

Adults follow a different path into martial arts than kids do. They need classes that fit into their lives, feel safe to learn in, and give them a reason to keep showing up.

Today, I'll show you how to build adult martial arts classes that attract beginners who become regular students. If you're looking to get more people in the building, take a look at our guide: marketing martial arts to adults.

Why Adult Martial Arts Classes Fill Differently Than Kids Classes

Kids' and adult programs share a building, but it would be a mistake to assume that they function the same way.

The biggest difference between the two? Who comes to class and what motivates them to stay.

Adults choose; kids are chosen for

A child usually attends because a guardian—mom, dad, grandma—signs them up.

Adults decide whether a particular martial arts program deserves a spot in their schedule, budget, and personal life.

Parents will probably encourage their kids to go to class, even when they'd prefer to stay home. Adult attendance is much more fickle; if anything goes wrong—injury, social confrontation, the class is boring—they can leave. An adult who loses interest can simply stop attending.

Most of the time, they never tell you why they left.

Your adult program needs to earn student commitment continually—through your gym's schedule, quality of instruction, outcomes, and student experience.

If you've already got a kids program in your gym, the opportunity to attract the adults in their family is huge.

A kids' program means you already have a few dozen adults in your lobby every week. The bridge is the parents. Recruit them and you have a steady supply of new members for your adult program.

The Gymdesk Benchmark Report 2026 found that gyms with kids' programs average about 237 members, compared with 107 for adults-only gyms. The takeaway isn't to replace your kids' program; it's building an adult program that complements it.

The hobbyist majority

Most adults aren't training to become professional fighters or win tournaments.

They're looking for a community, hobby, fitness, self-defense, confidence, or a way to learn something challenging.

Combat Sports Academy's Lakea Vargas puts the split in numbers:

You build your adult classes around the 99% who just want to train consistently. Don't create a curriculum for superstar athletes who are looking to go pro.

Build for the 99. Your competitors will still find the hard rounds.

Build the Adult Class Menu

You don't need a dozen different classes for your adult program. You just need a small number of classes with a clear purpose and function.

Not sure which classes to offer? Take a look at our guide: martial arts classes to offer. It's a practical guide that covers a variety of options.

Five class types cover most adult programs.

The beginner class

A dedicated beginner class is one of the biggest levers you can use to fill and retain adult students.

At 10th Planet Long Beach, their academy had been stuck at six to 20 students for two years. They added a beginners class, and the headcount climbed to 35–40 students in year two and 90 in year three.

Nova Jiu-Jitsu's Jason Plaisted sees beginners leave when they're introduced to sparring too soon. New students need time to learn the fundamentals; that's because, most of the time, they can't keep up with experienced partners.

Build a curriculum that gives your beginners a clear progression they can follow.

At my gym, we pair beginners with an instructor or experienced student. Each lesson has beginner, intermediate, and advanced portions. This works well—it's a straightforward way to keep new students safe and ensure everyone gets something out of the class.

Experienced students are encouraged to take more risks, allow themselves to be caught, then work out of bad positions. New students learn about etiquette, technique, and timing. Experienced students work to improve their teaching skills as they walk new students through each technique.

The mixed-level core class

This is the meat and potatoes of your adult program, where most of your adult members will train.

Beginners with solid fundamentals can transition into the regular adult class, where they continue learning alongside the more experienced students.

Each class is structured so everyone has something to work on, regardless of their skill level or overall experience.

Here's how we do it.

We pair beginners/less-experienced students with upper belts. Beginners receive technique; experienced students receive advanced steps in the same technique.

When we pair beginners and experienced students together, both grow quickly. New students watch upper belts, taking note of the way they apply the technique. Experienced students get a deeper understanding of danger, and they improve their defensive skills significantly.

The fitness-first class

The goal is simple: Give students a legitimate way to participate before they feel comfortable with contact.

OB Jiu-Jitsu Collective uses Muay Thai as a bridge for people who aren't ready or comfortable with rolling yet. Two Bridges Muay Thai marketed itself on fitness at the start, because "martial arts" makes a lot of people think about getting hit.

Some adults focus on the fitness benefits of martial arts without the pressure that comes with sparring.

With grappling arts (e.g., judo, jiu-jitsu, wrestling, sambo), the fitness portion is baked in, and contact comes in stages. For beginners, flow rolls and games are a great way to build comfort.

Striking arts are a bit different.

The whole point of striking is creating contact. Fitness-focused students are turned off by the idea of sparring.

Fight-focused students are eager to spar. Most of your beginners will likely be hobbyists who are fitness-focused.

In a striking class, that's bags, pads, and conditioning with no sparring yet.

The women's class

A few of the women I've worked with weren't ready to train physically with men.

A women's fundamentals class is a great option here. It can give adult women a more comfortable on-ramp if they feel uncomfortable training in a co-ed, mixed-level room.

NEO Martial Arts' Solana Be explains that women may initially try martial arts for self-defense, but "it's not actually the reason why they stay… what keeps you coming back and back is having a really fun class, one that challenges you, but a really good community of people who support you through it."

OB Jiu-Jitsu Collective runs a free women's class on Sundays. At Forte Jiu-Jitsu, the owner said the gym was almost half women the last time he checked.

A dedicated women's class helps your students build confidence and community (especially important for women) before they're invited to join the wider program.

For a detailed breakdown, check out our guides to women's jiu-jitsu classes and the best martial arts for women.

Over-35: pacing based on performance

When you're working with adults over 35, it requires nuance.

Older adults who have been inactive for a long period of time may need a more gradual approach to training.

Then there are your athletes. Some people over 35 are in phenomenal shape. These people run circles around younger students who are in their "physical prime."

The absolute worst thing you can do with these athletes is treat them like senior citizens. They don't want to hear grandpa or senior citizen jokes. They're likely to take special treatment as an insult.

Just treat them like any other student.

You don't need a separate "seniors" class for your 35+ students. You do need to make sustainable training a priority for everyone in your gym.

Adayama Jiu-Jitsu's Marty Herrick cautions students over 35 to pump the brakes, stating that three or four days of training each week is plenty: "If you do more than that, you're kind of pushing your body to a place where, you know, there's injuries that are on the horizon, especially if you're over like the age of 35."

ITC New York's judo program offers a slower grading path for older members who never plan to compete.

Marty at Adayama recommends caution and there's definitely a place for that.

As a gym owner myself, I prefer to let the students choose how they want to approach their training. If they're easing back into training or not very athletic, we'll follow their lead and recommend that they take it easy. If they're training like a superhero, we watch them closely so they're not taking on unnecessary risk.

Schedule Around Adult Lives, Not Your Coaching Calendar

Adults have other priorities—they have to structure their training around work, family, and other responsibilities.

We're all incredibly busy; make sure that the time they spend with you is time well spent.

Anchor your week around an evening class or time slot that works well. Then make sure every additional slot earns its place in their life.

Anchor the evening

Adayama's Marty Herrick says Tuesday night in his gym is always the biggest adult class. It usually draws 35–40 people.

This is an example from one school; it's not a universal best practice you need to follow here. Focus on finding your best-performing time slots, then build around them.

Place beginner classes in or next to that anchor time slot so new students can train when the regular members are already there.

Add slots only when the room asks

You don't want to add classes simply because your instructors have a lot of free time. It's wise to add them when students are asking you for another time slot or opportunity to train.

Here's how you can go about this:

• Ask students about the time slots they're interested in.
• Choose a new time slot from the options students give you (e.g., a noon class on Wednesday).
• Open bookings for the new slot.
• Use these bookings to gauge interest and commitment level.
• Run the first class and gauge the level of interest.

Avoid the trap of offering too many sessions. You'll want to avoid situations where you're offering more time slots when there's limited demand.

Carlson Gracie Hackney's Konrad describes the trap of offering too many sessions: "Because you have 20 members and 50 classes. What do you want?"

A minimum of two sessions a week for your core classes is a pretty useful floor—especially if you're trying to build a habit. Can't keep up with that frequency? Look for ways to combine your classes before making the leap or splitting the schedule further.

Run adults next to kids

TEAMS MMA starts its kids' and adult grappling classes at 5:30 p.m. NEO Martial Arts runs its women's class at the same time as the kids' class, on purpose, for the "jiu-jitsu moms" who used to wait in the lobby.

It's a practical way to turn an existing family relationship into adult membership.

Here's an example of an adult-only weekly schedule. Tailor this to your school's actual attendance and demand.

Your numbers will move it around. Check attendance by class for a month before you add or cut anything.

Fill the Class From Inside Your Own Building First

Build from the inside out.

Before you invest in advertising to attract new people, take a look at the adults and families who are already bringing their kids to you.

Outside-the-building tactics belong in your adult marketing plan. Inside your academy, your job is to make the next step obvious for the people already in your building.

Turn parents and friends into adult students

NEO's Solana Be mentioned seeing moms waiting in the lobby, scrolling on their phones while their kids trained.

Offer these parents a beginner class in the same time slot.

I mean, they're already sitting there.

Take it a step further with a bring-a-friend night. This is a great way to introduce adults to training via someone they trust.

Your first offer depends on your gym's selling style.

If you're all about aggressively pursuing the sale, the direct approach can work here. Offer parents a free trial, then membership at the family rate.

If you're customer-service oriented, a sign in the lobby and a general announcement at the end of class or after student promotions is a great start.

Give beginners a runway, not a drop-in

OB Jiu-Jitsu Collective takes a bold approach; they offer a six-week free introduction for people who have never trained.

"A lot of gyms do one week free trials… but for somebody who's never done it before, it's scary at first."

A one-week trial can feel intimidating for new students, especially if they're still figuring out the details—gym etiquette, what to wear, where to stand, and whether they'll be expected to spar.

A structured trial program gives beginners the time they need to learn the basics and decide whether they want to continue.

If you're ready to expand your trial program, take a look at our guide to trial programs.

Follow up the same day

Here's a simple rule you can follow.

Every trial student hears from you the day of their first class. Here's an example message you can customize.

"You did it, you just finished your first jiu-jitsu class. What did you think? Easier/harder than you expected?"

Assuming that you've got their number, a text message is the easiest option for follow-up. Email is the next best option.

The Gymdesk Benchmark Report found that about 73% of real free trials convert to paying members, and half of those sign up within the first 10 days. When software handled the follow-up, 85% of trials converted, against 71% when owners chased each lead by hand.

I know, I know, correlation is not causation.

It's not hard proof that software alone produces this difference. Still, the takeaway is clear here: follow up with every trial the same day.

Make the First 90 Days Do the Retention Work

Adults who quit during their first month don't usually explain why.

Design the first 90 days so new students have a reason to keep coming back.

The Benchmark Report found that approximately one in five new members quit inside of 90 days. Same thing happens with members who rarely attend—they tend to quit at about twice the rate of those who train three or more times a week.

Again, that's a correlation, but it points the same way: the more often a new member trains early on, the likelier they are to stay.

Across the fitness industry, about a third of members are gone within a year. The HFA 2025 report puts annual retention at 66.4%. The first 90 days are where you get ahead of that.

To see what that churn costs your gym, run your numbers through our member retention calculator.

Week one

Give every new student a fundamentals-only class and someone they've connected with.

Two Bridges Muay Thai uses a three-friend rule. The front desk is a new student's first friend.

The front desk introduces them to a coach, their second friend. The coach introduces them to another student, and that's friend number three.

Every beginner has a familiar face to look for whenever they walk onto the mats.

Weeks two through five

This is make-or-break time for their training habit.

Watch for students who attend once or twice and then disappear. If new students miss seven days of training, a coach should reach out with a personal text.

You've gotta walk a fine line here.

If you're reaching out just to "get them to come in," you're better off saying nothing. Your reach-out is a personal check-in, an opportunity for you to ping them and see how things are going. Students are looking for a certain level of sincerity here—the kind that communicates care, guidance, and protection.

Here are a few simple messages you can use:

• "Hey man! Haven't seen you in a few days. You doing okay?"
• "You came up in conversation today. Just want to make sure you're doing okay after last week's comp class."
• "We're all planning on checking out the escape room in town this weekend. You in?"
• "Jimmy's ordering pizza for CJI this weekend, you coming?"

It doesn't have to be about training specifically; it's you reaching out and showing that you care. That's the important detail.

It works out because the fifth-class cliff is an important reminder to monitor student attendance. It's the point where new members begin to lose momentum.

Days 30 to 90

Give students visible signs of progress.

Reach out to them with a coach check-in. Keep sparring where it belongs. Something that comes after the fundamentals.

A beginner who sees progress continues to train. The first 100 days are an opportunity to turn a new member into a regular and, hopefully, a lifer.

Let Your Software Watch the Room

Can you imagine tracking all of the details we've discussed manually? In a spreadsheet?

Some of the gyms I visit still rely on manual methods—4x6 note cards, spreadsheets, Post-it notes. It's just too difficult to track manually; things eventually fall apart. The Gymdesk Benchmark Report echoes this: 43% of gyms still take attendance by hand.

With gym management software, you can track attendance by class. This gives you a bird's-eye view—see which time slots deserve to stay and which should be eliminated or combined.

Use attendance tracking and attendance metrics to gauge the difference between a class that needs more students and one that simply needs a different time.

Trial follow-up ensures that every new student receives a timely response. Good lead management software helps your team stay on top of that process.

Again, follow up with your trial students the same day. If you're using gym management software, the text still goes out on a busy night.

Weeks two through five is make-or-break time for new students building a training habit. You're watching for the student who has missed several classes.

Absence filters flag any member who hasn't checked in for a set number of days, so a new student who's been gone a week gets a text before they're gone for good.

Family accounts connect the kids' side and the adult side. The parent is already on file, so adding them to a family membership is one step, not a new sign-up.

These parents are already in the lobby waiting for their kids. With the right approach, this is a golden opportunity to "turn parents into adult students."

Replacing personal relationships isn't the goal here. It's making sure your staff has the information, tools, and reminders they need to maintain them.

Fill the Room by Fixing the Path, Not the Ads

Start with your best evening class. Find the night your adults already show up for, put a beginner class right next to it, and invite the parents who are sitting in your lobby during kids' class.

Then watch who comes back the second week.
