If you're a gym owner trying to figure out how to grow revenue without burning out your coaching staff — or yourself — small group personal training deserves a serious look.
The model goes by a few names: small group training, semi-private personal training, SGPT, 6-on-1. The format varies slightly depending on who you ask, but the core concept is the same: one coach, a small number of clients (typically 2–8), intentional programming, and a price point that lands between group classes and 1-on-1 training.
It's not a new idea. But it's become one of the most discussed formats in the independent gym space — and for good reason. When it's run well, it delivers coaching quality that retains clients long-term, revenue per session that makes the math work, and a community dynamic that's genuinely hard to replicate in a larger class format.

Here's what it actually is, how it works, and what you need to know before building your gym around it.
The Basic Definition
Small group personal training is a coaching format where one trainer works with a small group of clients simultaneously — usually 2 to 8 people per session.
Unlike a large group class, the programming is personalized to each individual. The coach knows each client's goals, tracks their progress, and adjusts training based on what they actually need. The small size of the group is what makes this possible: with 4–6 people in a session, a coach can actually watch each person move, cue corrections in real time, and maintain the kind of ongoing relationship with a client that drives results and retention.
Unlike 1-on-1 personal training, the cost of the coach's time is shared across the group — which means clients pay significantly less per session while the gym earns more per coaching hour than it would in a traditional 1-on-1 model.
That's the value proposition in one sentence: better unit economics for the gym, better affordability for the client, better retention than large group classes.
Why Gym Owners Are Moving Toward This Model
The math is the starting point for most gym owners who start taking SGPT seriously.
In a standard 1-on-1 model, a coach can realistically see 5–6 clients per day before quality drops. Revenue is capped by available coaching hours. It's hard to scale without hiring, and hiring is hard when your revenue-per-coach is limited.
In a large group class model, you can get volume — but the coaching ratio gets so thin that it becomes difficult to deliver the kind of individualized attention that drives long-term retention. Clients churn faster. The product feels commoditized.
Small group training changes both of those dynamics. A coach running sessions of 4–6 clients can see 20–30 clients in a day while maintaining genuine coaching quality. Revenue per coaching hour goes up. Client outcomes improve because the coaching is real. Retention improves because clients feel known.
Mark Fisher — who built Mark Fisher Fitness into one of the most recognized independent gym brands in the country and sold it after generating $34 million in revenue — now runs a semi-private small group franchise in New Jersey alongside his consulting firm, Business for Unicorns. He's deliberately chosen the small group model for his current gym because of what it produces: "It's profitable, and it has that coaching quality," he's noted — adding that it's one of the models he most consistently recommends to the gym owners he works with.
That's not an accident. The model works across a wide range of gym types, sizes, and markets — which is why it keeps showing up in the conversation.
How Small Group Personal Training Differs from Other Training Models (Including Semi-Private Personal Training)
Understanding SGPT means understanding what it's not. Here's a side-by-side comparison of the three most common coaching formats:
The key variable is the ratio. Most gym owners and coaches who run successful SGPT programs land between 4:1 and 8:1 (clients to coach). Below 4 and you're essentially doing semi-private at a discounted rate. Above 8 and the individual attention that defines the model starts to erode.
What Good SGPT Programming Looks Like
The programming is what separates small group training from expensive group fitness. If your sessions are just "workouts" that happen to have a few people in them, you're not running SGPT — you're running a small class.
True SGPT has:
An intake and assessment process. Before a client's first session, you understand their goals, training history, limitations, and what success looks like for them. This isn't just a formality — it's what enables you to actually individualize the training.
Individualized programming within a group framework. The session has a structure that works for everyone in the group, but weights, modifications, progressions, and scaling are specific to each person. A client coming off a knee surgery and a competitive athlete can train in the same session if the programming accounts for both.
Progress tracking. You know what each client lifted last week. You know their benchmarks. You can show them where they were six months ago versus today. This is one of the most underutilized retention tools in fitness — clients who can see their own progress stick around.
A defined training cycle. Sessions should connect to each other. There's a reason you're doing what you're doing this week as opposed to last week. Periodization doesn't have to be complicated, but it should exist.
The Revenue Model
The pricing math on SGPT varies by market, but the general structure looks like this:
Most SGPT gyms sell memberships rather than session packages, which improves cash flow predictability and reduces the feast-or-famine dynamic that plagues session-based models.
The other revenue lever worth understanding: retention. Small group training clients, when the program is run well, stay significantly longer than large group class clients. According to IHRSA research, gyms with strong personal coaching relationships see meaningfully lower monthly churn rates. The combination of real coaching, visible progress, and community belonging creates stickiness that's genuinely hard to replicate. Longer client lifetimes mean more revenue from the same acquisition cost — which is the core driver of margin in any gym business.
Common Challenges to Plan For
The model has real advantages, but it's not without friction.
Scheduling complexity. Unlike open group classes where anyone can show up, SGPT often involves assigned groups or time slots. Managing scheduling — especially as you scale — requires good systems. This is one of the areas where gym management software pays for itself quickly.
Group cohesion. The small group dynamic is an asset, but it takes intentionality to build. Clients who train together regularly start to form relationships that anchor them to the gym. That doesn't happen automatically — it happens because coaches foster it.
Programming overhead. Individualized programming takes more preparation than programming a single class workout. Most gyms solve this by creating tiered templates that can be scaled and adjusted, rather than writing fully custom programs for each client from scratch.
Ratio discipline. The most common mistake in SGPT is letting groups get too big. Once you're running 10+ people per session, you've left the model. It might feel like growth, but you're eroding the product quality that drives retention — and you'll feel it in churn before you recognize the cause.
Is SGPT the Right Model for Your Gym?
It's worth asking honestly. The model isn't the right fit for every gym or every operator.
It tends to work best when:
- Your core value proposition is coaching quality, not cheap access to equipment
- You want a membership-based revenue model with predictable monthly recurring revenue
- You have (or can hire) coaches who are genuinely good at individualization and client relationships
- Your market has demand for premium-ish fitness that isn't as expensive as 1-on-1
It's a harder fit when:
- Your current clients are primarily there for the large group energy and don't want personalization
- You don't have coaches with the skills to track and adjust individual programming
- Your facility is set up for high-volume throughput rather than intentional small group training
The gym owners who make it work tend to share one thing: they've made peace with the fact that SGPT is a coaching-first business, not a facility-first business. The product is the relationship between coach and client. Everything else — the space, the equipment, the software — exists to support that.

Frequently Asked Questions About Small Group Personal Training
How many people are in a small group personal training session?
Most successful SGPT programs run between 4 and 8 clients per coach per session. Below 4, the economics start to resemble discounted 1-on-1 training. Above 8, the individualized coaching quality that defines the model begins to erode. The sweet spot for most gyms is 4–6.
How much does small group personal training cost?
Clients typically pay $30–$60 per session, or $200–$500 per month on a membership model. That's significantly less than 1-on-1 personal training ($80–$150/session) while delivering a far more personalized experience than large group classes ($10–$25/session).
What's the difference between small group personal training and group fitness classes?
The defining difference is individualization. In SGPT, the coach knows each client's goals, tracks their progress, and adjusts programming to fit their needs — even within a shared session. In a large group class, everyone follows the same workout with little to no personalization. The coach-to-client ratio in SGPT (1:4 to 1:8) makes real coaching possible, whereas group class ratios (1:15 to 1:30+) make it impractical.
Can I transition my gym from a group class model to SGPT?
Yes, many gym owners successfully make this transition. The key is to do it gradually — start by offering a few SGPT time slots alongside your existing classes, invest in coach training around individualized programming, and let client demand guide how quickly you shift. The right gym management software makes the scheduling and billing transition significantly easier.
