Although each pregnancy is different, there is at least one constant that every woman can count on: Managing the moving target of rapidly-growing boobs.

With a new set of knockers comes a whole host of fun side effects, such as tenderness, veins, pigment changes, bumps and leaks. While I’ve yet to deal with the latter items on that list, I have outgrown all of my bras and am in desperate need of solid support for any kind of high-impact activity.

The only problem? Well, when you go from being able to wear pretty much any sports bra to suddenly needing to be picky about certain features, you don’t have a clue about where to start.

Luckily, Zensah came to my rescue. Not only is the company considered a pioneer of graduated compression apparel, but they’ve also created a new line of seamless sportswear designed with a second-skin fit for greater performance, comfort and mobility.

Having landed in foreign territory, I saw the “high-impact support for larger cup sizes” description of the Gazelle Sports Bra ($53.99) and figured it would do the trick. It’s designed with both encapsulation and compression to provide comfortable support — not to mention it’s seamless, which is a lifesaver, because when you’re eating and peeing around the clock, all you want to do is cut down on any added potential annoyances.

As you can see, the engineered fabric creates a separator with shaped cups that contour to the body (i.e. encapsulate the ladies) for a natural, smooth fit. Zensah’s high-density Zupport Yarn™ also helps support its claim that this is the first truly seamless sports bra to support mid-to-high-impact activities (i.e. compression at its finest).

Factor in wide, soft straps to prevent dig-in and zoned ribbing for extra support and, according to the company, it’s also 250% more supportive than their other seamless styles. Plus it’s pretty cute, right?

From the back, you can see how it’s got a body-mapped design for breathability, plus a keyhole to encourage freedom of movement. The proprietary fabric is moisture-wicking and anti-odor to help keep you fresh and dry, too.

Best of all? I flipped it inside out, and it’s truly seamless! I’m usually skeptical about that claim since any kind of rogue raw edge can rub and chafe, but this one’s soft and smooth.

Ok, ok, I know — enough about what it’s made of and what it looks like. Does it actually work?

Well, as they say, the proof is in the pudding. I tested the Gazelle on several runs and it did not disappoint.

In fact, on my very first run with it, I had the best four-miler I’ve had in months. I’m not sure if it was that there was no painful jostling — or maybe because my rib cage could finally expand properly — but I could barely feel it on, it was so comfy.

And that, my friends, is the mark of a good bra.

So good, in fact, that I’ve also resorted to wearing it under street clothes while I’m on my next mission: Upgrading my real bra. Sigh.

Any other tips for wrangling ‘the ladies’ while working out?
