Whether you're a AA or a DDD, you can probably agree on one thing: A proper sports bra can make or break your workout. There's no shortage of them on the market after the past few years, during which athleisure took center stage over...well, just about everything, so you pretty much have your pick when it comes to brands, materials, features and price points. Rather than trying to track them down across the web, however, we're taking the fast-track to comfort with the best Amazon sports bras across all categories.

As a certified personal trainer and a workout enthusiast, I happen to know a thing or two about what to look for among the site's hundreds (actually, make that thousands) of options, including how they should fit and what types will suit you best. From compression models to padded ones that promise to keep you feeling secure, supported and looking fly as heck while you run, jump and everything in between, you can find my picks for the cream of the crop below—along with some pro advice about how to choose between them.

Types of Sports Bras

First thing's first: You'll need to know what it is you're looking for as far as the type of sports bra you're after.

  • Compression sports bra: This type of sports bra pushes your breasts against your body to reduce movement. They tend to work best for those with smaller cup sizes.

  • Encapsulation sports bra: These have a separate cup for each breast that's designed to hold them in place and keep them apart. They're also usually lined with an underwire.

  • Encapsulation-compression sports bra: A combination of a compression and an encapsulation sports bra, this offers separate cups in addition to added pressure to keep everything firmly in place, making it a great choice for those with larger cup sizes.

  • Longline sports bra: These bras have slightly more fabric than your average ones, coming down below the bustline and ending at the waist.

How Should a Sports Bra Fit?

As with a regular bra, while you want your sports bra to fit snugly, it shouldn't be so tight that it smashes the girls down uncomfortably or digs into your back. You also want the straps to sit flush and closely against your shoulders. This way, they'll pick up some of the slack or sag that will be inherent in the cups (unless you’re wearing a chest binder, the soft material of a sports bra cup won’t support you on its own).

When looking for the right sports bra size, it's best to start with your regular size in tops (oftentimes, sports bras will adopt the sizing system of traditional apparel, with options like small, medium, large). You'll know it's too big if the band rides up or the cups are creasing or wrinkling as a result of having too much room between your chest and the material. Another quick test? If or you can fit more than two fingers under the bust band, you probably want to go down a size.

You'll want to keep in mind, however, that when you heat up during a workout, your skin is likely to swell and accumulate sweat, so it's best to factor that in when you try a sports bra on. To make sure you've got it right, you can mimic a few quick movements that you plan to perform during your workout, such as high knees, skipping or jogging or even a downward dog or wheel pose for yoga. This way, you'll get a better sense of how your sports bra will fit for its intended purpose.

Where to Buy a Sports Bra

In addition to specialized athleisure retailers, such as lululemon, Alo Yoga or Sweaty Betty, you can find sports bras at big box retailers, such as Nordstrom, Target, Macy’s and Bloomingdale’s, or sporting goods stores, like Dick's, Nike, adidas and Under Armour. Or, you could head to Amazon and shop tons of options with Prime two-day shipping to your heart's content—I've given you a pretty good headstart below.

1. Lululemon Energy Bra

Best Longline Sports Bra

  • Why We Love It: Removable cups, strappy design

I'll never stop singing the praises of athleisure powerhouse lululemon. You should add its longline Energy bra in particular to your running roster for its removable cups, supportive, sweat-wicking fabric and strappy back construction, which will look fabulous peeking out of a baggy sweater or worn on its own. It’s ideal for medium-intensity activities, such as cross-training, power yoga and hiking—particularly if you're a B- to C-cup gal.

Size range: 2 to 14

2. Under Armor Infinity Sports Bra

Best High-Impact Sports Bra

  • Why We Love It: Adjustable straps, mesh paneling

Whether you’re training for a race or jumping rope, a high-impact sports bra, which is typically designed with extra-wide straps and more secure bands, will be your best bet when it comes to bounce-reduction. This Under Armor pick, which happens to be a favorite of more than one PureWow editor, has proven to keep everything in place with its adjustable criss-cross straps, convenient hook-and-eye closure and injected foam pads, which deliver the ultimate comfort and support—so much so, in fact, that our associate editor, Stephanie Sengwe, called it "so good you forget you have boobs.” It also boasts a mesh paneling that will keep you cool during even the most grueling of workouts (think CrossFit or climbing).

Size range: XS to XXL

3. Sweaty Betty Yoga Bra

Best Low-Impact Sports Bra

Sometimes, the best workouts don’t feel like work at all. Treat your torso to this buttery-soft Sweaty Betty sports bra, which will be ideal for low-impact activities, like yoga, stretching, barre and Pilates. Its seamless construction guarantees a next-to-nothing feel that's elevated by the stretchy, elastane material (all the better to help you get into poses you never knew your body was capable of). There are removable pads that will allow you to customize your preferred level of support and a racerback that will keep you from tugging at your straps as you attempt to master crow pose, once and for all.

Best Padded Sports Bra

  • Why We Love It: Vibrant colors, strap stabilizers, removable padding

It’s made with stretchy, quick-drying recycled polyester and comes in several bold colors, like bright citrus and limelight. What's more, when you need a little extra support, which can be hindered by padding, as it allows breasts to move around without a perfect fit and creates a barrier between the compressive fabric, you can easily remove the added cushioning.

Size range: XS to XL

Best One-Shoulder Sports Bra

  • Why We Love It: 4-way stretch, shrink-resistant

We have fitness influencers to thank for the growing popularity of one-shoulder sports bras.
