Couples Who Do This Together Have Stronger, Healthier Marriages

Married couples who exercise, whether together or alone, report better communication, fewer serious arguments, and a stronger ability to resolve conflict, according to a new study published in Family Relations. Couples who worked out together showed somewhat larger associations with those positive outcomes than couples who exercised separately, though that difference was not statistically significant, meaning it could be a chance finding. That pattern held for both husbands and wives.

Plenty of people already know that hitting the gym or going for a run does wonders for stress and mood. This research points to a benefit that reaches past the individual and into the relationship itself, and it shows up whether a person exercises alone or alongside a spouse. Shared workouts carried the stronger link to healthy relationship habits, but because that edge fell short of statistical significance, researchers cannot say for certain it reflects something real rather than chance.

Researchers studied data from 1,693 young married couples across the United States, making this the first nationally representative study to look at whether exercising together specifically links to how couples communicate and handle conflict, rather than just how satisfied they are in their marriage overall.

Who Took Part In The Study?

Participants were drawn from the Couple Relationships and Transition Experiences (CREATE) project, a nationally representative survey of newly married young couples in the United States. Couples were selected using a two-stage process that sampled counties and then recent marriages within those counties. Both partners had to complete the survey for a couple’s data to be included. At least one partner in each couple was between 18 and 36 years old at the start of the study, and all participants were in the early years of marriage. Most couples in the study married in 2014.

Household incomes ranged from below $30,000 to above $130,000, with the average household falling in the $60,000 to $79,000 range. While a majority of participants identified as White, more than 30% came from Black, Latino, Asian, Native American, and multiracial backgrounds. About 46% of couples in the sample reported having children.

Participants were asked whether they engaged in regular physical activity, then asked to list up to three types of exercise they typically did. Researchers then asked whether each activity was done with a spouse. If either partner said yes for any activity, it was coded as exercise done together as a couple. Responses covered a wide range of activities, from running and weightlifting to walking, and even categories like “kid activities,” which included responses such as “chasing my daughter” and “carrying one or two 30-lb children for 5 hours at a time.”

Shared Exercise and the Marriage Numbers

Both individual and shared exercise were linked to better marital communication and conflict resolution, and less marital conflict, for husbands and wives alike. Comparing the two side by side, exercising together consistently carried somewhat stronger associations with positive relationship outcomes than exercising alone, but that gap was not statistically significant for any of the outcomes measured, meaning researchers cannot say with certainty it is real rather than a chance finding.

A wife who exercised with her husband showed a stronger association with better communication scores than one who exercised on her own, and a similar pattern appeared for husbands. Those associations held even after researchers accounted for factors like age, education, income, race, work status, and whether the couple had children. Even with the shared-exercise numbers running larger across the board, the same not-significant caveat applies. Still, results pointed in the same direction across all three outcomes, communication, conflict resolution, and marital conflict.

Having children was also associated with poorer communication and conflict-resolution scores and greater conflict. Drawing on earlier research, the authors connect the transition to parenthood with added stress and fewer chances for shared leisure, though this study did not test why parents reported different relationship outcomes.

Reasons Couples Who Exercise Together May Benefit

Researchers point to a few possible explanations, though none were proven by this study alone. One is that shared physical activity simply gives couples uninterrupted time together, away from the demands of work, kids, and other responsibilities. That time creates natural opportunities for open conversation. Another possibility, drawn from existing research, is that exercise may produce physical changes in the body, like improved self-control and calmer emotional responses, that could carry over into how couples treat each other. Authors describe this as a potential spillover effect, but stress that this study cannot confirm the mechanism.

Walking was among the most common forms of shared exercise reported, which the researchers found encouraging. It requires no gym membership or special equipment, making it one of the more accessible ways for couples to stay active together.

Practical Takeaways for Couples and Counselors

Because poor communication and unresolved conflict rank among the leading contributors to divorce, the study’s authors suggest that therapists and marriage educators consider recommending shared physical activity as a practical, low-cost addition to their work with couples. A therapist could, for example, assign a couple a walk together as homework between sessions. Marriage education programs, which commonly focus on communication and conflict, could fold shared exercise in as a simple, flexible tool. Authors are clear that this is a suggestion for practitioners to explore, not a proven treatment.

Authors are careful to note that the study cannot prove cause and effect. Because the data were collected at a single point in time, couples who already communicate well may simply be more likely to exercise together, rather than the exercise itself driving the better communication. Longer-term studies that track couples over time are needed to sort out which direction the relationship runs.

For young couples navigating the pressures of early marriage, the takeaway is a plain one: going for a walk together, or even just going for a walk at all, might do more for a relationship than either partner realizes.
