This post is more for the ladies than the gentlemen, so feel free to bail or head off to a more testosterone-filled spot on the Internet.
That said, a good sports bra is super important if you're engaging in moderate- and high-impact workouts. When I began exercising, all I had was the standard "uniboob" pullover sports bra, which I bought at Target.
For the smaller chested, that may suffice, but if you've got a lot upstairs, say a Farmer's Porch, then you need more infrastructure. And if, like me, in addition to that Farmer's Porch you've got a porch swing, two Adirondack chairs and a lazy dog, you need much more support.
"Get Sports Bra" was one of those To-Dos I figured I'd get to when I got to it. It was not a priority, even when running, but I knew it would be sooner than later.
A couple of weeks ago, @MelGetsFit tweeted about Enell, which makes sports bras for the more-endowed. (If you don't follow @MelGetsFit, do so immediately. She shares a ridiculous amount of great weight-loss/fitness info.) I took this as a sign it was time to right my bra wrong.
Enell makes it very easy to determine your correct size and even learn how to put it on. It's more than a bra, more like a half-tank-top with a lot of support. I've been running in my Enell Sport bra for a week now and I love it. The support is fantastic and it's very comfortable.
If you think you need a little more support up top, check them out.
