I'm a 36 DD. I like to stay active, but hate bounce.
This bra is perfectly adequate for low impact activities (yoga, weight lifting), but any activity that requires more movement (such as speed walking, basketball, running, off road biking) it fails miserably. If you jump up and down in this, its downright painful how much your breasts move up and down.
Furthermore, I found the bra unattractive under a t shirt. I've had the same experience with many other Shock Absorber bras.
I mainly use this bra with another low support bra to give adequate support. However, for this price, you are better off buying a couple of cheaper bras and using two at the same time. If you want a bra that you don't need to layer and that will eliminate bounce, keep looking. This is not the bra for you.Get more detail about Shock Absorber Women's Extreme Support Classic Sports Bra #109.

This bra is SO comfortable. I have never had a supportive sports bra that was comfortable before. I picked it up at a local store, and the ladies there were very helpful helping me find the right size. I wear these every day when working out, and they are absolutely wonderful.

I have finally found the perfect 'hanging around the house' sports bra. I LOVE the zipper!!! So easy to put on. I have had zipper kind of sports bras before but they all were terrible ~ not supportive. This bra has 'structure' to it for support but is like wearing nothing at all. It is also sort of cute. It makes me feel like I look good even in my lounge clothes! LOL I also use this for exercise and again the support is outstanding. This sports bra is so comfortable and supportive that I have even considered wearing it as a "regular" bra. I am a 38DD regular but I ordered the 40DD CW-X bra and it fits like a glove.

I bought my Powerback at the same time as I got the Powersleeks. The Powersleek is definitely superior for bounce control. Because I run sometimes (in addition to cardio kickboxing and other bouncy stuff), that's my top concern with a sports bra--it HAS to control bounce! And at 36C, I can't afford to let the girls loose once in a while.

Pros: It's OK for low- to mid-impact stuff, like regular step aerobics, elliptical, walking, or yoga. And it gives you enough separation that you look like a woman, not someone in an Elizabethan costume.

Cons: Just not enough support for the price. And the biggest PITA of all? Putting it on over my head! What good are back hooks if you have to hook them before you put the bra on? I never fail to catch the underwire somewhere on my head or neck and end up getting myself all tangled up in the stupid thing. If you have someone around to help you put your bra on before every workout, might not be an issue. For me, though, the Powerback is basically a bench warmer because it's such a PITA just to get it on. And it's even harder to take back OFF again if it's all sweaty and damp--you need the jaws of life to get you out of this thing.

Summary: If it's loose enough to get over your head, it's probably not tight enough to give adequate support for running. Well, that's *my* experience, anyway. Pass on this one, and get a bra you can hook normally. Get more detail about Champion Women's Powerback Underwire Sports Bra #1694.

I usually use the really cute looking Nike sports bras that come in all different colors but I'm on a deployment and I didn't want to bring those with me. I ordered these because they looked basic and they weren't too expensive and they had good reviews. I LOVE THEM! I'm a runner and I wear a C/D cup and these bras are awesome. They give you so much support without smashing your boobs to your chest or creating the "uni-boob" that you get from most sports bras. I ran a few miles to test it out and had pretty much no bounce, the bra did exactly what you want a sports bra to do. I highly recommend these!Get more detail about Champion Jogbra Action-Shape Sports Bra Womens.

I workout a lot and I had yet to find a good fitting sports bra that really worked for me, till I found this one and I've never been happier. This is really a bra I could use, and I have used. I run and do a lot of aerobic style things, but in every situation it held up to it's standards. I recommend this to everyone who wants to keep `em in when they workout.Get more detail about Under Armour Heat Gear Endure D Zip Front Sports Bra Womens.

This is a great bra but I should have bought a larger size. If you want no bounce and total, total control this is it. Just make sure you measure yourself before buying. I love mine I just wish I would have gotten it in one size larger.Get more detail about Moving Comfort Women's Athena Bra.
