The latest preliminary research confronts a common assumption: that exercising while wearing a chest binder is inherently unsafe. Shared ahead of a full academic publication expected later in 2026, the work examined several physiologic and performance measures and reported no significant differences between sessions performed with a binder and sessions in standard exercise clothing. The authors describe the results as an important early step rather than a conclusive verdict, and they emphasize the need for more research before definitive clinical guidance can be issued. This article outlines the study, its findings, and what it does and does not tell us about binding during exercise.
A chest binder is a compression garment used to flatten the chest, often adopted by trans, gender diverse, and gender non-conforming people to align physical appearance with gender identity. Binding is widely practiced: some studies report that up to 87% of trans and gender diverse people assigned female at birth have bound their chest at some point. Community and clinical reports link binding with reduced gender dysphoria and improvements in anxiety, depression, and overall quality of life. Given these mental health benefits, policies and advice that discourage exercise while binding can force a difficult choice between physical activity and psychological wellbeing.
About the study
The research was led by Mx Kai Schweizer and Associate Professor Bonnie Furzer through the Mental Health and Exercise Research Group (MHEX) with collaboration from community advisors such as Sock Drawer Heroes, lived-experience contributors, and partner organisations. The trial enrolled 21 adults presumed female at birth who had never used a binder previously. Each participant completed two supervised exercise sessions: one while wearing a professionally fitted binder and one in standard exercise attire. The team measured objective outcomes including lung function, upper body strength, cardiovascular fitness, and subjective comfort during activity, aiming to capture short-term physiological effects under controlled conditions.
Participants and protocol
Volunteers were fitted with binders by professionals to ensure a correct fit for the experiment, and testing protocols followed standard exercise science procedures. Respiratory measures assessed how breathing mechanics performed during exertion; strength tests evaluated upper-body capacity; and cardiovascular assessments quantified aerobic response and recovery. The controlled comparison design—each person acted as their own control—reduced variability linked to individual fitness differences. Importantly, these were short, supervised sessions, not long-term or real-world training conditions, which limits how far the results can be extrapolated beyond the lab environment.
Key findings and implications
The headline result was that there were no significant differences in any of the measured outcomes when participants exercised in a correctly fitted binder compared with standard exercise clothing. In practical terms, this suggests that wearing a binder—when it fits properly—may not reduce short-term physical performance or capacity. If corroborated by larger studies, these findings could lower a major barrier to exercise for people who experience chest dysphoria, potentially improving participation rates and the associated physical and mental health benefits. Past surveys show many people bind while active despite warnings; a study of trans and gender diverse teenagers reported that 84% had exercised while binding.
Context from other research
These preliminary results align with a separate study published in 2026 of teens who regularly bound, which also found no significant impact on exercise capacity. Together, the emerging literature challenges blanket cautions against binding during activity and calls for evidence-based guidance that balances physical safety with mental health needs. Community-led research partnerships were instrumental in shaping study questions and procedures, highlighting the value of co-designed investigations when addressing issues that directly affect marginalised populations.
Limitations and next steps
The authors are careful to note limitations: the study only assessed short-term effects during supervised sessions and did not measure outcomes such as skin irritation, thermoregulation, or long-term musculoskeletal impacts. All participants wore properly fitted binders, so results may not apply when garments are ill-fitting or worn for prolonged periods. The researchers explicitly state that the work “does not prove there are no risks associated with binding during exercise” and call for larger, longer-term studies that examine real-world conditions and a broader range of health metrics.
For now, the evidence invites a shift toward nuanced, evidence-based advice rather than categorical bans. Health professionals and community organisations can use these findings to inform discussions about safe practices—such as ensuring a correct fit, adjusting intensity, and monitoring comfort—while researchers pursue more comprehensive investigations. Continued collaboration between scientists and affected communities will be essential to produce guidance that protects physical health without undermining the mental health benefits many people experience from binding.
