How to Choose the Right Sports Bra

No matter your bust size, excessive movement can lead to discomfort, so the right sports bra is essential for your training. Learn how to find a bra that fits you comfortably — in the gym and beyond.

When we’re working out, we need a sports bra that delivers that just-right level of coverage. A little looser for yoga, a little more support for that five-mile run.  Never too restrictive or too relaxed.


1. First, Find Your Band Size
With your shirt off and wearing your favorite bra, wrap a soft tape measure around your back and just above your bust, where your bra strap meets your bra. Keep in mind, the tape measure should be snug but not tight. This measurement is your band size.

2.  Next, Determine Your Bust Size
Wrap the tape measure around your bust at its fullest point. If this measurement falls between numbers, round up to the next inch.

3. Calculate Your Cup Size
Finally, subtract your band from your bust size and use the chart below to determine your cup size.


Now that you know your band and cup size, think about the features you need in a sports bra: 


Sports bras are designated by their impact level. This ranges from low to high-impact. Remember, regardless of activity, you should wear the bra that feels most comfortable to you:

  • Low-Impact Sports Bras provide light support. These bras are best for yoga, weight training or walking for C and D cup sizes. Women with A or B cup sizes may be able to perform more activities in these bras.

Low impact

  • Medium-Impact Sports Bras are great for activities like skating, biking or skiing for C and D cup sizes. A and B cup sizes may be able to perform more intense activities in these bras.

Medium Impact

  • High-Impact Sports Bras are designed for activities that require a high level of support, particularly for C and D cup sizes. Try this bra for running or aerobic activities.
