Referral Programs for Gyms and Studios
A gym referral brings in more than one new membership, because the friend who joins becomes a training partner, and research on people who start a program together suggests the pair is more likely to keep showing up than either would alone.
At a glance
- A gym referral program gives members a well-timed invitation to bring someone, a reward the friend can use on day one and a way to train together, so the referral turns into a pair rather than a single sign-up.
- In a randomized trial published in the Journal of Consulting and Clinical Psychology, 95% of people recruited with friends and given social support completed a four-month program, against 76% of those who joined alone with standard treatment.
- Referred customers are worth more; in a study of about 10,000 bank customers in the Journal of Marketing, a referred customer's value was at least 16% higher and the risk of leaving about 18% lower.
- For an illustrative 300-member studio, raising the share of members who refer from 8% to 12% adds about seven members and about $10,800 in dues a year.
Part 1 | The friend is the program
Most gym referral programs are built like a coupon, with a free month for the member who sends a name, and the owner's instinct is often We need a bigger reward. The research on exercise and behavior change points somewhere else, toward what happens after the friend joins, because the reason a friend referral matters in fitness is that the two people hold each other to the schedule.
The clearest evidence comes from a 1999 trial of 166 people in a four-month weight-loss program, who enrolled either alone or with three friends or family members and were then assigned to standard treatment or treatment with added social support. Among those who joined alone with standard treatment, 76% completed the program and 24% kept off all the weight they had lost through month ten; among those recruited with friends and given social support, 95% completed it and 66% kept the weight off.
The study is older and was about weight loss rather than gym memberships, yet the direction matches what a studio sees in its own data: members who come with someone tend to come more.
Part 2 | Reward the friend, and ask at a high point
Two findings from marketing research shape the reward. Field experiments reported in the Journal of Marketing Research found that referral rewards given to the new customer brought in more referrals than rewards given only to the referrer, because recommending something that comes with a gift reflects well on the person recommending it. Experiments reported in the Journal of Marketing found that rewards raised referral likelihood most when the friend was a weaker tie, such as a coworker, and less for a sibling or close friend who would have come anyway.
For a gym, that points to a reward the friend can use on the first day, such as two free weeks of classes or a waived joining fee, with a smaller thank-you for the member, and to an ask that makes coworkers and neighbors feel welcome rather than only spouses.
The timing belongs at the high point of the membership. Research on remembered experience in Psychological Science found that 22 of 32 people chose to repeat a longer, more uncomfortable trial because it ended more gently, so the ask lands best at moments that end well: the cooldown after a personal best, the class that marks a member's 50th visit or the morning a member finishes a six-week challenge.
Part 3 | Make the pair, then make the next referral
Referred members tend to refer others. In a study drawing on ten years of data from a cashback company with 41.2 million registered customers, published in the Journal of Marketing Research, referred customers made 31% to 57% more referrals than comparable customers, and a message telling referred customers "You were referred in, now refer your friends" raised referrals by 21% in a field experiment with about 10 million people.
The ask, from the coach after a strong class
"That was your 50th class here. If there's someone at work or on your street who keeps saying they want to start, bring them Thursday; their first two weeks are on us, and we'll pair you up in the same sessions."
The welcome, to the new member
"Glad you came in with [member's first name]. You were referred in, so you have two free weeks to pass on to someone too."
| Active members (Assumption) | 300 |
|---|---|
| Share who refer someone in a year, today (Assumption, near the 7.6% rate in the cashback study) | 8% |
| Share who refer with the program (Assumption, near the 11.9% rate among referred customers in that study) | 12% |
| Referred friends who join (Assumption) | 60% |
| New members from referrals, today (Calculated (300 × 8% × 60%)) | 14.4 |
| New members from referrals, with the program (Calculated (300 × 12% × 60%)) | 21.6 |
| Average months a new member stays (Assumption) | 10 |
| Monthly dues (Assumption) | $150 |
| Added dues per year (Calculated ((21.6 − 14.4) × 10 × $150)) | $10,800 |
Illustrative example; replace every assumption with your own numbers. It leaves out any lift in the referring member's own attendance.
How you compare
- Share who refer: in the cashback study, 7.6% of customers who joined on their own made a successful referral; count how many of your members brought someone in the last 12 months.
- Value of referred members: in the bank study, referred customers were worth at least 16% more; compare the average tenure of members who were referred with those who were not.
- Pairs: count how many referred members booked their first five classes with the person who referred them.
Questions to ask this week
Who receives our referral reward? If only the member does, test a first-day reward for the friend.
When do we ask? Tie the ask to a milestone or a finished challenge, not to a monthly email.
Do referred members know they were referred? Tell them, and hand them a pass to share.
Do new members train with the person who brought them? Book their first sessions together.
The next step is to choose one milestone this month, such as the 50th class, and have the coach make the ask at the end of that class for every member who reaches it.
About this research: This article draws on a randomized trial in the Journal of Consulting and Clinical Psychology, studies of referral rewards in the Journal of Marketing Research and the Journal of Marketing, a study of referral contagion at a cashback company, a study of bank customers in the Journal of Marketing and research on remembered experience in Psychological Science. None of the referral studies were run at gyms, and the social-support trial is from 1999, so the effect sizes are a guide rather than a forecast. The worked example is illustrative.
