Can a Sports Bra Improve Your Horse Riding Position?

A well-fitting sports bra may help your riding position as well as your comfort—particularly in trot. A small simulator study found that breast support changed riders’ torso position and symmetry. That makes bra fit worth checking alongside your technique and conditioning, not a substitute for either.

What the riding research found

A peer-reviewed study published in the International Journal of Equine Science in September 2026 tested 21 female equestrians. Each participant rode an equine simulator at walk, trot and canter and ran on a treadmill in four conditions: an everyday bra, an encapsulation sports bra, a combination sports bra and no bra. Researchers measured movement with motion capture and collected pain and comfort ratings. Hartpury’s publication record.

Both sports bra designs tested reduced breast movement and exercise-induced breast pain in trot and running. In trot, torso position improved in both sports bras compared with the everyday bra; riders were most symmetrical in the encapsulation design. Comfort and preferences varied between individuals. Read the study’s abstract.

These are useful findings, but they do not establish a best bra for every rider. The study compared specific designs on a simulator, not riding live horses over months of training. The researchers call for larger, longer-term field studies. Nor does the result show that a sports bra will correct every collapsed shoulder, uneven seat or unstable hand.

Which type should you try?

An encapsulation sports bra supports each breast in a separate cup. It is a sensible design to include in your fitting shortlist, given the symmetry finding—not a guaranteed winner. World Rugby’s breast-health guidance also explains that separate-cup support is particularly worth considering for athletes with larger breasts. That is general sports guidance, rather than riding-specific proof. Breast support and bra fit.

A combination sports bra adds a layer of compression to separate-cup support, as explained in The Well HQ’s guide to sports bra styles. Include one in your comparison if it fits comfortably: the combination design tested also improved torso position in the riding study.

Do not choose solely because a product says “running” or “equestrian”. Hartpury’s research summary notes that breast movement during riding differs from running, so support designed mainly around running data may not be optimal for riders. Check the actual fit and your response to riding movement. Hartpury research summary.

Check fit before getting on

Try the bra under your usual riding top. If you wear a body protector, check the complete outfit too.

Use these basic fit checks:

• Band: level around your body, close-fitting and comfortable—not riding up.
• Cups: contain the whole breast without spilling or gaping. Fit the larger breast if your breasts differ in size.
• Straps: stay in place without digging into your shoulders.
• Underwire, if present: follows the breast crease without pressing into breast tissue.
• Movement: the bra stays in place when you raise your arms overhead.

These checks follow Breast Cancer Now’s fitting guidance. Use the size label as a starting point; fit varies by style and brand.

Then do a simple off-horse check: sit on a firm chair with feet supported, hold your hands as though carrying reins, and take several comfortable breaths. Raise and lower your arms, then hinge forward gently as you would when preparing for two-point position. Notice restriction, slipping or pressure. This is a comfort check, not a simulation of trot or proof of riding support.

Assess it in a normal lesson

With your qualified instructor, compare comfortable options during work you already do safely. Do not ride without support to recreate the experiment, or add sitting trot just to test a bra.

Keep a short note of:

• Breast discomfort during and after the ride.
• Whether you need to adjust the bra.
• Your instructor’s observations of torso lean and left–right position.

A more comfortable ride is useful even without a visible position change. If a position fault remains, continue coached work and off-horse rider fitness rather than tightening the straps further.
