How to choose a sports bra?

Exercising without a well-fitting sports bra? That's asking for trouble—both with comfort and health. Whether you're running, doing yoga, or strength training, the right sports bra is the foundation of a successful workout. But how do you choose one? What should you pay attention to—size, type of support, or perhaps material? In this article, we'll clear up any doubts and offer tips on how to choose a sports bra that perfectly suits your needs.

Why is it worth wearing a sports bra while exercising?

Exercising in a classic bra can do more harm than good. During physical activity, the breasts move in all directions—up, down, and side to side. This not only causes discomfort but can also lead to stretching of the Cooper ligaments , which are responsible for breast firmness. The result? Over time, the breasts can lose their shape, even if you wear a small cup size.

A sports bra provides support and protection , regardless of the intensity of your workout. It limits breast movement, distributes weight evenly, and reduces the risk of chafing. It also guarantees greater freedom of movement and mental comfort – you can focus on your workout, not on adjusting your bra. Furthermore, modern models offer not only functionality but also a great look, which further boosts self-confidence.

What types of support are there in sports bras?

When choosing a sports bra, the level of support it offers is crucial. Manufacturers typically divide sports bras into three categories: low, medium, and high support . Each type meets different needs – both in terms of activity and bust size .

• High-support bras – ideal for intense workouts like running, HIIT, or CrossFit. These bras feature a sturdy construction, wide straps, and often two separate cups. They provide maximum support, even for larger busts.
• Medium support – perfect for cycling, strength training, or fitness. They provide good support while allowing for greater freedom of movement.
• Low-support bras – suitable for gentle activities like yoga, stretching, or Nordic walking. They usually feature a soft top without underwires or support.

When choosing the level of support, it's important to consider not only the intensity of the exercise but also the size of your breasts. Larger breasts require more support , even with gentle exercises.

How to choose the right sports bra size?

The wrong size is the most common reason why even the best sports bra doesn't perform as expected. A well-fitting model should be slightly tighter than a classic bra , especially around the bust area—this area provides most of the support.

To choose the correct size, measure in two places:

• Under the bust – tight, on the exhale, the measuring tape should adhere to the body.
• In the bust – looser, at the height of the nipples, without pressing on the breasts.

The measurement under the bust is rounded down (e.g., 73 cm = circumference 70). The cups should cover the entire breast and restrict its movement, without flattening or squeezing the breasts sideways.

The right size is the basis of comfort and effectiveness – so before purchasing, it is worth consulting the size chart or trying on several models.

What should you pay attention to when choosing a material?

The material from which a sports bra is made has a huge impact on comfort during training. A well-chosen material helps prevent chafing, overheating, and moisture , which is especially appreciated during intense exercise.

What is worth paying attention to?

• Breathability – the best sports bras are made of technical materials that wick away sweat and provide good skin ventilation.
• Elasticity – materials with added elastane guarantee a better fit and freedom of movement without pressure.
• Soft and seamless – smooth finishes and seamless constructions reduce the risk of chafing, especially where straps and elastics come into contact.

Avoid thick cotton styles – although soft, they retain moisture and stretch quickly . Instead, opt for modern, lightweight, and quick-drying materials that move with your body as you move.

Which sports bra is best for large breasts?

If you have larger breasts, choosing a sports bra requires special attention. Inadequate support can cause back pain, chafing, and discomfort with every step . It's not just the size that matters, but also the design.

What to pay attention to?

• Wide band under the bust – responsible for stabilizing and supporting the weight of the breasts.
• Adjustable, thick straps – prevent digging into the shoulders and allow for a better fit.
• Separate cups – provide better support for each breast individually and limit their movement.
• High support – this is an absolute must, especially when running or jumping.

It's also worth choosing models with a back closure – over-the-head styles can be more difficult to put on and don't offer as good a fit. A sports bra for large busts isn't a luxury, but a necessity – an investment in comfort, health, and confidence during every workout.

What to choose: a padded or wire-free bra?

Many women associate a sports bra with a soft, unstructured top. However, the market offers both padded and non-padded models – each with its own advantages, depending on the type of activity and individual preferences.

This non-wired bra is lightweight and pressure-free—perfect for yoga, Pilates, or walking. The compression design presses the breasts closer to the body, restricting their movement. It's ideal for women with smaller breasts or those who engage in moderate activity.

A padded model with contoured cups (often without metal underwires) provides better separation and stability. This is a good choice for larger sizes or more intense exercises, such as running.

Important: Not every padded bra has underwires . Modern models use soft, flexible inserts or special support zones. If comfort and support are important to you, choose a hybrid – a soft but well-constructed sports bra that doesn't pinch and holds everything in place.

Which sports bra is best for running?

Running is one of the most dynamic activities, requiring maximum support and stabilization . While running, the breasts can move several centimeters in any direction, which, without a proper bra, can lead to pain, chafing, and even damage to the breast tissue.

The ideal running bra should have:

• High support – encapsulation construction (separate cups) or compression + encapsulation (combination of compression and separate cups).
• Wide straps and a band under the bust – preferably adjustable to adjust the fit to your figure.
• Soft, quick-drying fabrics – wick away moisture and minimize the risk of irritation.
• Back clasp – makes it easier to put on and increases the durability of the bra.

For women who run regularly, a good bra is an investment in their health and comfort—no compromises necessary. Oh!Zuza offers models designed for active women who want to look stylish and feel confident on every run.

And which one for yoga and pilates?

Yoga, Pilates, and stretching are activities that require freedom of movement, softness, and comfort , not necessarily maximum support. In this case, a sports bra should feel like a second skin—imperceptible, yet still functional.

The best choices are low- to medium-support bras , often in the form of unwired tops. Ideally, they should have wider straps, a flexible construction, and soft padding that won't compress the breasts while providing subtle support.

What to pay attention to?

• Seamless finish – prevents chafing in positions requiring contact with the mat.
• Breathable fabric – Even gentle exercise can cause sweating, so technical fabrics still matter.
• Flexibility – the design should work with the body without restricting the range of motion.

Harmony is key in yoga, including in your attire. A comfortable sports bra will allow you to focus on your breathing, posture, and relaxation without distracting discomfort.

Summary: How to choose the perfect sports bra?

Choosing the right sports bra is a key element of any athletic wardrobe. It's worth taking a moment to analyze your needs: your type of activity, your body type, and the comfort level you want to achieve. The right size, well-chosen support, and breathable material are the three pillars of effective protection and comfort during your workout.

Whether you're running, stretching on a mat, or spending time at the gym, a properly fitted sports bra will allow you to focus on moving and achieving your goals, without distracting discomfort.
