🔁 Simple Retargeting: A 3-Step Facebook Ads Strategy for Gyms

Here's the one-sentence version: Retargeting means showing a second ad only to people who already noticed your first one.

Think about a lemonade stand at a busy park. Lots of people walk by. Some don't even look. But a few slow down, glance at the sign, and keep walking. Those few are not "no." They are "not right now." If you could tap just those people on the shoulder a day later and say "Hey, still thirsty? First cup's free," a lot of them would say yes.

Facebook lets you do exactly that. It remembers who slowed down. Then you show your offer only to them.

Why It Works So Well

Showing an offer to total strangers is hard. They don't know you. They don't trust you. Most won't click. Showing the same offer to someone who already watched your video for 20 seconds is easy. They've seen your face. They've heard your voice. They already like you a little bit. So they click more, and because they click more, Facebook charges you less.

Warm vs. Cold

You'll hear the words cold and warm a lot. Cold means a stranger who has never seen you. Warm means someone who has already watched, clicked, or visited. Retargeting is just "talk to the warm people."

Run a Video to Find the Interested People

The first step is not about selling anything. It's about finding out who's a little bit interested. A video is the best tool for this, because Facebook keeps track of who watched it and for how long.

What Kind of Video

Short, helpful, and real. You, on your phone, in your gym. No script, no fancy editing. Some ideas:

• "The one thing everyone gets wrong on their first day at the gym"
• "3 stretches for people who sit at a desk all day"
• "What our 6 a.m. boot camp actually looks like" (just film the class, with permission)
• "Why most people quit the gym in week 3, and how we fix that"
• "A 5-minute warm-up you can do in your living room"

Aim for 30 to 90 seconds. Say something useful. Smile. Done.

How to Set Up the Ad

1. In Ads Manager, pick the goal "Engagement," then "Video views."
2. Audience: people within 5 to 10 miles of your gym, in your real member age range. That's all.
3. Budget: $3 to $5 a day. This is the cheap part.
4. Write one friendly line above the video: "Desk job wrecking your back? Here's what I tell every new client."
5. Let it run. Don't touch it for at least a week.

Turn the Watchers Into a List

Now Facebook knows who watched your video. Step 2 is telling Facebook: "Make me a list of those people." Facebook calls this a custom audience. Think of it like a guest list. Facebook keeps the names; you just decide who gets on it.

How to Build the List

1. In Ads Manager, open "Audiences."
2. Click "Create Audience," then "Custom Audience," then "Video."
3. Choose how much of the video someone had to watch to count. We like "watched at least 25%" or "watched at least 10 seconds." That filters out people who scrolled past but keeps the ones who paused.
4. Pick your video (or all your videos).
5. Set how long people stay on the list: 90 days is a good start. 180 or 365 if you want a bigger list.
6. Name it clearly, like "Watched 25% - last 90 days."

Make a Second, Hotter List Too

While you're here, make one more list for people who watched 75% or more. These folks watched almost the whole thing. They're very warm. You might show them a slightly stronger offer later.

Other Warm Lists Worth Making

• Visited your website in the last 30 days (needs the Meta Pixel on your site, which is a small snippet your web person can add in 10 minutes)
• Engaged with your Facebook or Instagram page in the last 90 days (liked, commented, messaged)
• Opened your lead form but didn't finish it
• Your old leads and past members, uploaded from a spreadsheet

Show the List a Friendly Offer

Now the fun part. You have a list of warm people. Time to invite them in.

What the Retargeting Ad Says

These people have seen your face. Talk to them like you already met. Because you kind of did.

• "Thanks for watching! If you want help getting started, I'm opening 10 free trial weeks this month. Want one?"
• "You saw what our 6 a.m. crew is like. Come try one class on us. No pressure, no pitch."
• "Our 6-week Fit Habit Challenge starts the 1st. We keep it to 20 people so the coach knows everyone's name. Want a spot?"
• "Still thinking about it? Totally fine. Here's a free 15-minute call with a coach to see if we're a fit. No workout, just a chat."

How to Set Up the Ad

1. Goal: "Leads." Use Facebook's built-in form so people never leave the app. Ask only for name, phone, and email.
2. Audience: your "Watched 25%" list. Nobody else. Make sure you exclude people who already filled out your form, so you're not paying to show offers to people who already said yes.
3. Budget: $3 to $10 a day. Warm lists are small, so you don't need much.
4. Picture or video: use a still from the video they watched, or a new short clip of you saying hi. Familiar faces get clicks.
5. Run it for 2 weeks, then look at your numbers.

Use More Than One Retargeting Ad

Since you're showing ads to the same small group, they'll see the same ad a lot. That gets old. Make 2 or 3 versions and rotate them:

• The invite: free week or free session
• The story: a short clip of a member (with permission) talking about how they felt before and after their first month. About confidence and energy, not body shape.
• The answer: "The 3 questions everyone asks before joining, answered in 60 seconds."

Text Them the Moment They Say Yes

You did all this work to warm someone up. They finally click your offer and fill out the form. Now what?

Here's what happens at most gyms: the lead sits in an inbox until someone checks it the next morning. By then, the warm person has cooled right back down. The whole 3-step plan gets undone in one night.

The 5-Minute Rule

Set up automatic text follow-up. The second the form comes in, a text goes out, no human needed:

"Hi Maria! It's Lena from Strong Studio. Thanks for grabbing a free trial week. Does Tuesday at 6 or Saturday at 9 work better for your first class?"

If they don't answer, it texts again on day 2, day 4, and day 7. Short and friendly every time. Most people book somewhere in that window.

If you remember only one thing from this guide, make it this: Stop asking strangers to join. Ask the people who already paused.

The Big Ideas

• Most people need to see you more than once. Retargeting makes "more than once" happen on purpose.
• Give before you ask. The helpful video builds trust for a few dollars a day.
• Let the list grow. Patience in step 2 makes step 3 cheap.
• Keep step 1 running forever. It's the faucet that keeps your warm list full.
• Fast follow-up finishes the job. Without the 5-minute text, you're just warming people up for the gym down the street.

Week 1 — Film and launch step 1

1. Film 2 short helpful videos on your phone (30 to 90 seconds each)
2. Launch both as "Video views" ads, $3 to $5 a day total, 5 to 10 miles around your gym
3. Set up automatic text follow-up now, so it's ready before the first lead

Week 2 — Build the lists

1. Create two custom audiences: "Watched 25%, last 90 days" and "Watched 75%, last 90 days"
2. If you have a website, get the Meta Pixel added and build a "visited site, last 30 days" list too
3. Check which video is getting watched longest for less money. Keep that one, pause the other

Week 3 — Keep waiting (really)

1. Let the list grow. Check the audience size. You want 1,000 or more
2. Write your 3 retargeting ads: the invite, the member story, the "what to expect"
3. Make sure none of them promise weight loss or body changes

Week 4 — Launch step 3

1. Run the 3 retargeting ads to the "Watched 25%" list at $3 to $10 a day. Exclude anyone who already filled out a form
2. Confirm every new lead gets a text within 5 minutes and follow-ups on day 2, 4, and 7
3. After 2 weeks, write down cost per lead and how many booked. Compare it to what you paid before
