How To Choose A Performance Sports Bra For Training
Jan 20, 2026
Introduction
Choosing a sports bra can mean the difference between a joyful workout—or one that leaves you sore and uncomfortable long after the workout ends (and not in a good way).
When it comes to choosing a sports bra, there’s no one-size-fits-all solution. The right sports bra depends on your activity level, body type, comfort preferences, and support needs. That’s why we created this guide—to help you understand what to look for and how to choose a performance sports bra that actually works for you.
If you ever have questions or want personalized advice, we’re always happy to help you navigate how to choose a sports bra, feel free to reach out! 💛
💡 Did you know
The first sports bra—called the Jogbra—was invented in 1977 by sewing two jockstraps together. Its inventors, Lisa Lindahl, Hinda Miller, and Polly Smith, were runners frustrated by the lack of support available to women at the time. Sports bras have come a long way since then!
How To Choose A Sports Bra: Factors to Consider
Step 1: What Is Your Intended Activity?
One of the most important factors in choosing a sports bra is understanding how you’ll use it. A bra designed for yoga won’t provide the same support needed for running or mountain biking.
Low-Impact Activities
(Yoga, walking, stretching)
Light support
Prioritize comfort and flexibility
Medium-Impact Activities
(Cycling, strength training, hiking)
Moderate support
Balance between compression and comfort
High-Impact Activities
(Running, mountain biking, equestrian, HIIT, tennis, pickleball)
High support
Enhanced compression, coverage, and stability
Step 2: How Much Support Do You Need?
Sports bras are typically categorized by support or impact level, which helps indicate how much movement control they provide.
Low-Impact Sports Bras
Best for yoga, walking, or women who need minimal support.
Medium-Impact Sports Bras
Highly versatile and ideal for a wide range of activities and support needs.High-Impact Sports Bras
Designed with more coverage, wider straps, and supportive fabrics to control movement during intense activity.
💡 Tip: If you don’t need much support, you may still feel comfortable wearing a low- or medium-impact sports bra during high-impact workouts.

Step 3: What is Important to You?
Every woman has different pain points when it comes to sports bras. Think about what has bothered you in the past—and what you want to avoid in the future.
Anti-Chafing
Chafing is a common issue caused by friction between skin, sweat, and fabric. Key contributors include exposed thread edges and slow-drying materials.
Seamless or bonded seams reduce friction
Fast-drying fabrics help minimize moisture-related irritation
✨ Lume Six sports bras are made with fully bonded seams to reduce irritation. In an independent third-party study, they dried 5–19x faster than other leading sports bra brands.
Comfortable Straps
Straps should lay flat and maintain their shape without digging into your shoulders or neck. Poor structure or low-quality materials often cause straps to collapse and create pressure points.
Lume Six straps are designed to stay flat and include subtle cushioning for all-day comfort.
Fabric Performance - Lightweight & Fast-Drying
Performance fabrics make a difference no matter what, but especially if you sweat heavily or live in a warm climate.
A fast-drying sports bra:
Helps regulate body temperature during workouts
Feels more comfortable post-workout
Prevents that cold, sticky feeling
Style - Encapsulation vs. Compression
Sports bras provide support in two main ways:
Encapsulation: Supports each breast individually
Compression: Compresses the chest to limit movement
Personal preference plays a big role. Women with looser breast tissue often prefer encapsulation, while denser tissue may feel great with compression. Trying both styles is the best way to decide.
All Lume Six sports bras are compression-style.
Adjustability
Adjustable straps or bands can help fine-tune fit but often add bulk, hardware, and potential irritation.
If you can find a sports bra that fits well without adjustability, that’s often ideal. To reduce pressure points and discomfort, Lume Six sports bras are designed without hardware.
⚠️ Caution - Where Is the Support Coming From?
Some sports bras rely on a fully rigid band for support. While bands do provide most of a bra’s support, overly rigid bands can restrict breathing and movement—negatively impacting performance.
Look for bras that use premium compressive fabrics throughout, rather than relying solely on a stiff band.
Step 4: Get the Right Fit
Once you’ve narrowed down your options, fit is everything.
Tips for Finding the Right Fit:
Try it on. Ideally, test multiple sizes.
Check for spillage. Breast tissue should not spill over the top or sides.
Take deep breaths. You should breathe comfortably without restriction.
Move around. Jump, stretch, twist—don’t just stand still.
Assess the straps. You should fit two fingers comfortably under them. Straps shouldn’t carry most of the support.
Choosing the right sports bra improves comfort, performance, and overall workout experience.
Match your sports bra support level to your activity: low, medium, or high impact.
Look for features that matter most to you, like anti-chafing seams, comfortable straps, and fast-drying fabric.
Support should come from quality materials and design—not an overly rigid band.
Decide between compression or encapsulation based on personal preference.
Proper fit is key: avoid spillage, breathe easily, and move around before committing.
Final Thoughts on Choosing a Sports Bra
The best performance sports bra is the one that supports your body, your activity, and your comfort preferences. Taking the time to understand support levels, fabrics, and fit can completely change how you feel during—and after—your workouts.

Founder of Lume Six sports bras. I spent my career developing technical sports apparel. I created Lume Six because I knew sports bras could be so much better, but didn't see the big brands making great products in a category so important or women athletes. My main sport is mountain biking, but have been a life-long athlete across a variety of sports.
