What Are Sports Bras? Everything You Need to Know

Table of Contents

Looking for the perfect sports bra to keep you supported and comfortable during every workout? Let’s jump in with Olaben to explore what sports bras are, why they matter, and how to choose the right one for your activity, shape, and style.

What is a sports bra?

A sports bra is a specially designed bra that supports your breasts during physical activity. Unlike regular bras, sports bras reduce breast movement, prevent discomfort, and help protect breast tissue from strain or damage. They are made with performance-focused materials that wick moisture, provide breathability, and ensure a snug yet non-restrictive fit. Choosing the right sports bra can improve your comfort, posture, and even your athletic performance.

Why the Right Sports Bra Matters

Finding the perfect sports bra has never been easier. Today’s designs combine style and function, so you can feel confident even in high-support bras that once were all about practicality, not looks.

But a sports bra isn’t just about style—it’s about support, comfort, and performance. The right fit accommodates every breast size and shape, keeping you comfortable through every type of workout.

Wearing the correct sports bra doesn’t just protect your breasts—it enhances your athletic performance. Ill-fitting bras can cause discomfort, distraction, or even strain, so prioritizing fit and support is essential for both safety and confidence during exercise.

Types of Sports Bras

  1. Encapsulation: Separate cups support each breast individually. Structured, adjustable, and sized like everyday bras (e.g., 34C, 36DD). Ideal for larger busts and high-impact workouts.
  2. Compression: Applies pressure to hold breasts close to the chest. Pullover style, often with racerback, best for smaller busts (B cup or below) and medium-impact activities.
  3. Combination/Hybrid: Blends compression and encapsulation for fit and support. Suitable for all cup sizes and high-impact sports, offering both comfort and stability.

How to Find the Right Sports Bra Size

Now that you know why the right sports bra is so important, the next step is finding the perfect fit for your workouts. Unlike traditional bra fittings, you can measure your sports bra size at home in just a few simple steps.

What you need:

  • A non-padded, non-wired bra
  • A flexible measuring tape

Steps to measure your sports bra size:

  1. Measure your underbust – Wrap the tape snugly around your ribcage just under your breasts.
  2. Measure your bust – Measure at the fullest part of your chest while standing naturally.
  3. Check your size – Compare your measurements with a sports bra size chart to determine the correct fit.

For detailed instructions, refer to Olaben’s sports bra sizing guide.

Once you know your size, consider the support level your activities require. Yoga bras differ from running bras, and choosing the right level ensures comfort and protection.

How to Check if Your Sports Bra Fits

  • Straps: About 20% of support comes from straps. You should fit one finger underneath—tighten if too loose, but don’t over-tighten.
  • Underband: Provides 80% of support. It should sit firmly at your ribcage and stay in place when you raise your arms. If it feels loose, size down.
  • Cups: Test with movement. Your breasts should sit comfortably without bulging, poking, or leaving air gaps.

Understanding Support Levels

Sports bras are categorized by impact level:

  • Low-support: For yoga, walking, or stretching. Minimal bounce, maximum comfort.
  • Medium-support: For weight training, elliptical, or tennis. Moderate support with light shaping.
  • High-support: For running, HIIT, plyometrics, or other high-impact exercises. Maximum control and protection.

“Athletes may need the same amount of breast support during power walking as they do during sprinting. Lack of support can lead to long-term damage.” – Professor Joana Wakefield-Scurr

The right support level depends on three factors:

  1. The type of activity you do
  2. The size and shape of your breasts
  3. Whether your bust is soft or firm

Conclusion

Choosing the right sports bra is more than just a wardrobe decision—it’s an investment in comfort, support, and long-term breast health. The perfect fit helps reduce movement, prevent discomfort, and even improve your performance during workouts.
