You're spending money. You're posting on social media. You might even be running ads. But the leads aren't coming in, the phone isn't ringing, and your membership numbers have flatlined.
Sound familiar? After 20 years in the fitness industry, working with hundreds of gym owners, PTs, and fitness brands across the UK, I've seen the same patterns repeat over and over. Good businesses with great coaches and solid training environments, held back by marketing that simply doesn't work.
It's rarely because the gym is bad. It's almost always because the marketing has fundamental gaps that nobody has pointed out. Here are the five most common gym marketing mistakes I see, and exactly what to do about each one.
1. Relying on Word of Mouth Alone
"We get most of our members through word of mouth." I hear this from gym owners almost every week. Word of mouth is powerful. It's free, credible, and converts well. But here's the problem: it's not a strategy. It's a hope.
When word of mouth is your primary growth channel, you're hoping existing members will bring their friends. Some will. Most won't. Not because they don't love your gym, but because people are busy, and recommending a gym to a mate isn't top of anyone's priority list on a Tuesday afternoon.
You can't scale it. You can't predict it. And you can't build a business plan around it. When a quiet month hits, you've got nothing to fall back on.
The Fix: Build a Referral System That Actually Works
Word of mouth works best when you give it structure. Instead of hoping members refer friends, create a system that makes it easy and rewarding.
- Create a simple referral incentive. A free month, merchandise, or a discount for both the referrer and the new member. Make it tangible.
- Ask at the right time. The best moment is when someone hits a milestone: a new PB, their first 30 days, or when they tell you they feel great.
- Automate the ask. Use your CRM to trigger referral requests at key moments in the member journey. Don't rely on coaches remembering.
- Make it shareable. Give members a personal referral link or code they can text to friends. Remove every barrier between the thought and the action.
Word of mouth should be one channel in your marketing mix, not the entire strategy. Layer a referral system on top of paid acquisition and content marketing, and growth becomes predictable.
2. Posting on Social Media with No Strategy
This one hurts because gym owners put genuine effort into social media. They film workouts, photograph the gym floor, post member transformations. But it's sporadic. Three posts one week, nothing for a fortnight, then a burst of five on a Monday.
Random posting is worse than not posting at all. The algorithm rewards consistency and engagement. When you post irregularly, your reach tanks and the time you invest produces almost zero return.
The other problem is posting without a goal. Every piece of content should build trust, educate your audience, or drive a specific action. If your feed is just gym floor selfies and "come train with us" posts, you're not doing any of those effectively.
The Fix: Create a Content Calendar and Stick to It
Three to four quality posts per week will outperform seven rushed ones every time.
- Batch your content. Set aside two to three hours monthly to plan and create. Film multiple videos in one session. Write captions in advance. This is exactly what our content production service delivers for gym owners who'd rather spend their time coaching.
- Use a content framework. Rotate between educational posts, social proof (member results, testimonials), behind-the-scenes content, and direct calls to action.
- Plan around your business goals. Launching a new programme in March? Your February content should build anticipation. Reactive posting is always playing catch-up.
- Track what works. Which posts get saved? Shared? Drive profile visits? Do more of what works. Stop doing what doesn't.
Social media builds the trust that turns a cold stranger into a warm lead. But only if you show up consistently with content that means something to your audience.
3. Using Generic Stock Photography
I feel most strongly about this one, for obvious reasons. After two decades photographing fitness businesses: the imagery you use in your marketing is either your greatest asset or your biggest liability.
When a potential member lands on your website or sees your ad, they make a snap judgement within seconds. Generic stock photos of smiling models in a pristine gym that looks nothing like yours? They know immediately. And the trust you needed to build is gone before you've had a chance to earn it.
Stock photography strips away the one thing that makes your gym different: the real people, the real environment, the real energy.
The Fix: Invest in Authentic Visual Content
Your gym has a story. Your coaches have personality. Your members have real results. Show all of it.
- Get a professional shoot done. The images from one good shoot will fuel your marketing for six to twelve months across your website, social media, ads, and emails. We cover this in depth in our post on why stock photos are killing your fitness brand.
- Capture your coaches in action. People join gyms because of coaches, not equipment. Show your team coaching, interacting with members, and being themselves.
- Document real member journeys. Before and after content is powerful, but so are "during" shots. Show the process, not just the result.
- Create content in a proper environment. Our clients have access to eight purpose-built studios designed specifically for fitness content: gym floors, podcast studios, kitchen sets for nutrition content. The right environment transforms the quality of everything you produce.
Gyms that invest in authentic imagery consistently outperform those using stock. Better ad conversion, higher social engagement, and websites that feel trustworthy from the first click.
4. No System for Lead Follow-Up
The silent killer of gym growth. A lead fills in your enquiry form on Monday. Nobody responds until Wednesday. By then, they've signed up at the gym down the road that replied within 20 minutes.
The majority of gym owners have no formal lead follow-up process. Enquiries come in via Instagram DMs, website forms, Facebook messages, and phone calls. They end up scattered across platforms with no system to track them and no accountability for response times.
Responding to a lead within five minutes makes you 21 times more likely to convert them compared to waiting 30 minutes. After an hour, your chances drop off a cliff.
The Fix: Automate Your Lead Response and Build a Nurture Sequence
You need two things: speed and persistence.
- Set up instant automated responses. The moment someone enquires, they should receive an acknowledgement via text, email, or both. This buys you time while making the lead feel valued.
- Centralise all leads in one CRM. Stop checking five different platforms. Pull all enquiries into one place with automated notifications so your team knows the second a new lead comes in.
- Build a nurture sequence. A five to seven email sequence that educates, builds trust, and handles objections will convert leads over days and weeks that you'd otherwise lose.
- Set follow-up tasks. If a lead hasn't responded after your automated sequence, a personal phone call from a coach can make all the difference. But only if someone is reminded to make it.
The gyms that grow consistently aren't the ones with the most leads. They're the ones that convert the highest percentage of leads they already have. Our email and CRM automation service exists specifically to plug these gaps.
5. Running Ads Without a Funnel
"We tried Facebook ads, spent about a grand, got a few leads but nobody signed up. Ads don't work for us."
Except ads probably do work. The problem isn't the ads. It's what happens after someone clicks.
A gym owner boosts a post or runs a basic ad that sends traffic to their homepage. The homepage wasn't designed to convert cold traffic. No clear offer, no reason to act now, no mechanism to capture details. The visitor bounces. A thousand pounds wasted and a viable growth channel written off.
The Fix: Build a Proper Landing Page and Funnel
Ads are just the top of the funnel. Without the rest, they're worthless.
- A dedicated landing page. Not your homepage. A specific page built for one purpose: converting the traffic your ad sends to it. One offer, one call to action, no distractions.
- A clear, compelling offer. "Join our gym" is not an offer. "Get a free 7-day pass plus a goal-setting session with one of our coaches" is an offer.
- A follow-up sequence. Once someone opts in, they enter an automated sequence: confirmation, "what to expect," a reminder before their trial, and a check-in afterwards. This is where most conversion happens.
- Retargeting. Retargeting ads that follow up with people who visited but didn't opt in will recover a significant percentage of lost leads.

The Common Thread: Systems Beat Tactics
Every one of these mistakes comes down to the same root cause: a lack of systems.
Gym owners aren't short of ideas or effort. They're short of systems that connect the dots between getting attention and converting it into paying members. A great Instagram post means nothing without a funnel behind it. A brilliant ad is wasted if nobody follows up with the leads. Beautiful photography is underused if it's not deployed strategically across every touchpoint.
Marketing isn't one thing. It's an ecosystem. Every part needs to work together.
Quick self-audit: Score your gym out of 5. One point for each: a structured referral system, a content calendar you follow, professional photography of your real gym and team, an automated lead follow-up sequence, and a landing page funnel for paid ads. If you scored 3 or below, there's significant growth sitting on the table.
