It’s the end of a long day. You’re tired. Your to-do list is nowhere near finished. Do you head home to see your better half and start your evening, or do you drag yourself to the gym? Do you call your partner to meet you there?
Part of you knows the gym is worth the effort. The physical and psychological benefits are well-documented and widely known. Heart health, muscular strength, weight management—all of these plus stress and mood regulation, endorphins, a sense of accomplishment. The personal gains are compelling.
But if these personal gains aren’t enough, how about benefits to your relationship, particularly if you and your partner exercise together? New evidence points to strong associations between fitness and key markers of relationship well-being.
Exercise Makes You a Better Partner
An emerging body of evidence points to the pros of fitness not just for yourself, but for your relationship. This makes sense, given that romantic relationships require a great deal of mental effort. Romantic partners provide each other social support, share household responsibilities, and make decisions together about resources and future plans. These aren’t easy, but exercise may set people up to do well with these tasks.
Exercise offers individuals a way to improve their self-control. Yes, people with higher self-control tend to adhere to an exercise plan more easily, but exercise itself can help drive of self-control (Boat & Cooper, 2019). An intense workout can make it easier to override impulsivity, and be a better partner on account of that self-control.
An intense workout may also help with emotional regulation. A meta-analysis of randomized controlled trials showed that people’s abilities to regulate their emotions, including their ability to engage in emotional regulation strategies, was improved after physical exercise (Liu et al., 2022). When people can manage their emotions, they may do a better job managing conflict, navigating stress in the home environment, and supporting their partners.
Together, these findings suggest that exercises plays a role in supporting personal well-being, and in doing so, may help individuals as they navigate their relationships. In other words, when people take care of their physical and mental health through exercise, they’re better able to show up for their partner and their relationship.
Exercising Alone vs. Exercising with a Partner
Solo workouts are clearly helpful, but what if you work out together?
New research suggests that working out with your partner may be especially beneficial to relationships (Mildenhall et al., 2026). Analyses focused on exercise and marital quality data from 1,693 newly married couples who completed the Couple Relationships and Transition Experiences (CREATE) study, which is associated with Brigham Young University.
The CREATE study included open-ended questions, answered by both members of the relationship, about people’s own physical activities, which included running, biking, strength training, and playing with kids (almost 50 percent of the sample reported having children), among others.
People also indicated if they did these activities with their partner, thus allowing the researchers to separate “solo” from “joint” activities. Approximately one third of couples indicated that they workout together, typically through either cardio (33 percent), walking (20 percent), or strength training (15 percent).
Researchers also measured key markers of relationship success, including relationship listening and communication, conflict severity, and conflict resolution as part of the CREATE study.
Joint Exercising is Linked to Stronger Relationships
Results of this study showed that not only was individual exercise associated with better relationship functioning, but so too was joint exercising (Mildenhall et al., 2026). Couples who exercised together had fewer disagreements or conflicts, resolved conflicts more effectively, and were more likely to report strong communication. The links between joint exercise and relationship functioning held even in the presence of individual exercise, suggesting that something about exercising with a partner is uniquely associated with relationship well-being.
These findings inspire more questions: How does joint exercising compare to other shared leisure activities, be they goal-oriented or purely for entertainment? What happens with couples when one partner is highly motivated to exercise and the other is “dragged along”—do the same correlates persist?
Critically, this study relied on cross-sectional survey data: we do not know, and cannot infer from this study, whether joint exercise causes improved relationship quality or if the reverse direction is the causal path (i.e., that higher relationship quality makes joint exercise more likely).
Relationships Essential Reads
In all likelihood, it’s a probably a bidirectional effect. Happy partners may be well-set up to exercise together: and doing so maybe a wonderful way to fuel effective relationship functioning.
