If you’re a gym owner looking to increase membership with Facebook ads, but don’t know where to start, this guide is for you.

In this post, we’ll show you how to create Facebook ads for gyms that are not only eye-catching but also effectively communicate your message and encourage potential clients to take action.

We’ll cover:

  • What to know before creating your Facebook Ad
  • Key elements of a Facebook Ad
  • Writing engaging and persuasive short- and long-form ad copy

Our goal is to equip you with the knowledge to develop Facebook ads that resonate with your audience and help boost your gym’s membership.

Let’s jump right in.

Planning Your Facebook Ad: What to Think About First

There are two things to consider that will set the foundation for your campaign’s success.

Customer Avatar

Knowing your audience is the first step in creating an effective ad. Define your customer avatar to connect with the very people you want to attract to your gym.

Ask yourself these two questions:

  1. What does my ideal customer want or need? Understanding whether they want to lose weight, gain muscle, or find a community shapes how you’ll communicate in your ad.
  2. What does this person struggle with? When you know their fitness challenges, you can create an ad that offers solutions they’re looking for.

By answering these questions, you’ll tailor your ads to resonate deeply with your target audience, driving more meaningful engagement.

Front-End Offer

The front-end offer is your hook—it’s what captures interest and reels in potential clients. It should be irresistible, providing exactly what your ideal client wants or solving their biggest problems, encouraging them to act immediately.

Here’s how to make it effective:

  • Craft a clear call to action (CTA): Direct viewers towards a specific action like “Join Now” or “Learn More.” This should lead them to a landing page where they can easily leave their contact information (name, number, and email) and take the next step towards becoming a member.

Remember, your ad turns interest into leads by collecting contact details. Gym Lead Machine (GLM) streamlines this process for you, taking care of lead capture and follow-up to help you convert prospects into members.

The 5 Pillars of a Converting Facebook Ad

Your ad’s goal is simple: grab attention and prompt action, whether it’s a sign-up or a lead capture for nurturing.

Let’s look at the five elements that make this possible.

1. Image or Video: The Visual Hook

You need something eye-catching in the Facebook newsfeed, whether it’s an image or a 15-second video.

  • Choose images that reflect your brand and speak directly to your target audience.
  • Select videos that convey the point even on mute, as many people browse their feeds without sound.

Above all, prioritize high-quality visuals. A crisp, clear image or video not only looks professional but also holds potential clients’ attention, setting the stage for your message.

💡 Pro Tip: Determine which images and videos work best by testing and tracking your ad performance.

If you upload variations of visuals and text, Facebook’s dynamic creative will automatically figure out the best combination for you.

2. Headline: Capture Attention Fast

The headline is your ad’s initial “hey you!” to the world—it’s what stops people from scrolling. With only 40 characters available, make every word count.

Here are some approaches you can try:

  • Target your audience: Attention Busy New York Parents!
  • Solve a problem: Prepare Healthy Meals in Minutes!
  • Describe your service: Tough Workouts That Get Results!

3. Description: Quick, Extra Insight

Right beneath your headline is a small space for your description. You have 30 characters to briefly expand on your headline to provide a bit more detail.

Consider these examples based on our earlier headlines:

  • Effective 20-min HIIT workouts!
  • Dishes that hit the spot!
  • Burn hundreds of calories!

Your description should be compelling enough to drive people to click the call to action button next to it.

💡 Pro Tip: Write a mix of short and long ads, and let Facebook’s dynamic creative figure out which works best for your audience.

4. Body Text: Driving Action

The main text, or body text, is located above the image and is the meat of your ad, pushing people to take action. You have up to 125 characters to make your case, and there are two ways to go about it:

  • Short copy: This is perfect when attention spans are short and your offer is straightforward.
  • Long copy: This is ideal for storytelling, addressing doubts, and highlighting benefits. They can create a sense of urgency, use emojis for emphasis, and help pre-qualify leads to save your sales team’s time.

5. Call to Action: What’s Next?

Every effective ad guides viewers to the next step with a call to action button. This button takes your audience closer to what you promised in your ad.

Facebook offers a variety of options like Book NowWatch MoreGet Offer and so on, each tailored to your ad’s objective. Select the one that best matches your campaign’s purpose.

Writing Your Facebook Ad Copy: Short or Long?

Whether brief or detailed, your ad’s main text (i.e., body text) must be persuasive and engaging.

Short Facebook Ad Copy

In just 125 characters, or about 1-2 sentences, your message must be sharp and impactful.

Here are your best options to do just that:

  • Ask questions: Grab attention by speaking directly to your audience’s needs.
  • Solve problems: Offer a quick solution that relieves a specific pain point.
  • Show social proof: Build trust with testimonials that prove your gym delivers results.

Even with brevity, you can combine all of these elements. For example:

Another effective strategy is a 5130 post. The formula is simple:

💡 X people get 1 result in X time

For example: Looking for 5 people who want to improve their fitness dramatically in 30 days!

This creates creates urgency and focus with a targeted offer.

Short ad copy makes a big impact with a few words. Make every character count to ensure your audience takes the action you want, right away.

Long Facebook Ad Copy

Long-form copy appeals to those who need more information before committing. It’s your chance to:

  • Ask questions
  • Share stories
  • Connect with readers
  • Confront objections and address pain points
  • Build credibility
  • Promise change and results
  • Add urgency and scarcity
  • Ask for action

Long copy not only attracts the right fit for your gym but also filters out those less likely to engage, ensuring your CTA is clicked by genuinely interested prospects.

For a touch of personality, use emojis. They can make your ad stand out and people love seeing them.

Here’s an example of a concise long-form ad:
