The Difference between High vs. Low Impact Sports Bras

Have you ever thought you had chosen the wrong sports bra? Different sports bras have a big difference in your being supported during work-out sessions.

These compression sports bras don’t restrict your movement. Instead, they allow you to act and do exercises more comfortably. So what is the difference between high vs. low-impact sports bras? Which one should women be wearing? Follow us to get the answer.

What are Sports Bras?

Like regular bras, encapsulated sports bras come with two separate cups for your breasts. They offer the most effective support by minimizing the vertical and horizontal movement of the breast.

This way, they can protect the breasts’ delicate Cooper ligaments. If you are not wearing a supportive bra during a high-impact type of activity, the ligaments risk being stretched or broken by the movement and bouncing.

The results will be saggier breasts. This is why you should wear a supportive sports bra. Even smaller busted gals need this clothing item. You can choose high- or low-impact sports bras to suit your needs.

The Differences Between High vs. Low Impact Sports Bras

Low-impact activities include Pilates, yoga, and strength training. In these activities, your feet don’t have to pound the ground, resulting in less bouncing. That’s why the bra is designed to offer optimal comfort.

This type of clothing is unpadded and lightweight with narrower shoulder straps and soft stretching fabric. It is ideal for sports and activities requiring slower movement and flexibility.

You can also use it when doing housework or running errands.

On the other hand, high-impact sports bras are a must-have for workouts involving great impact on the ground floor. Aerobics, running, boot camps, and jump training are just a few.

This bra comes with padded cups, underwire, and wide shoulder straps. Each breast is well surrounded and supported by the defined cups.

Due to the denser and firmer fabric, it feels heavier than its counterpart. There may be side boning and a higher neckline to offer additional coverage.

Long story short, the main differences between low and high-impact sports bras are the offered support, materials, and suitable activities. You can refer to this video for a wrap-up:

Which One Should You Choose?


Bra sizing is undoubtedly of the utmost importance in choosing a perfect sports bra. Acknowledge the following red flags to get the right size.

If the bra says spillage, the cups are too small. In this case, remember to choose a less shallow shape or size up. Digging in straps indicates too loose bands. They cannot support the breasts’ weight, and you need a smaller one.

Rolling-up bands are a pointer of a too-small bra. On the contrary, too large cups will be puckering or wrinkling. So choose the one with a supportive band, smooth cups, and secure straps to have a perfect fit.

Our advice is to go for sports bras with adjustable bands so that you can tailor them when they stretch out. Also, cross out the brands specializing in sports clothing, such as Lululemon or Nike. They have little, if not no, experience in making bras for sure!

Level Of Support

Wearing a fit bra will minimize breast movement and avoid unwanted stretching. The level of needed support depends on the type of activities you will take and your cup size. There are three impact levels of bras. Take differences among low-impact, medium-impact, and high-impact to account. Then, decide on the one meeting your needs.


Sports bras are designed with various styles to offer different types of fit, support, and versatility. They will work best for your body if they snuggly embrace your breasts’ shape and size.

Racerback shows a “Y” back shape to allow freedom of movement and great mobility. It is pulled over your head and unadjustable. Thus, racerback bras are ideal for small busts.

Crossback bras come in a criss-cross shape to offer a range of motion comfort. It offers adjustment features to support a perfect fit and prevent slipping straps.

A scoop-back design is the most similar to daily and traditional bras. They are often used by women with large bust sizes thanks to their easy-to-wear design.

Padding Options

The padding determines the modesty and level of support of a bra. Removable cups will serve your needs if you want a bra with added modesty, support, and protection.

These cups are removable for great versatility. You can get either individual inserts or a one-piece pad. Built-in cups are available to complement the breast’s natural shape. They separate each breast to offer contoured and targeted support.

The integrated inserts are easy to wash and reduce the risk of losing cups. On the other hand, non-padded cups are common in traditional compression bras.

This type presses the breasts against your chest. They work best for smaller breasts, athleisure wear, and low-impact activities.


The article introduces you to the difference between high vs. low-impact sports bras. You should choose a suitable one depending on your purposes and type of activities.

However, it is worth staying away from Lululemon or Nike. These brands are not specialized in bras and offer overpriced items. Plus, avoid sports bras that cannot tighten the back closure or the band.
