Does woman really need sport bra?

One night around 10pm, I just didn't have anything to do. no website interested me any more, too early to go to bed. okay, I just wander to upstairs , good, treadmill, I decided to do a little bit exercise, walked on the treadmill for 3 minutes, I came down stairs. Hubby heard me walking down, "Honey, are you exercising? " ,“Yeah， didn't you hear it?", " Well, it runs only 3 minutes, are you done?" , he just looked at me with that weird smile , I　know　what that means : hey, I know you won't do it long as usual. I can read the word behind his smile. so, I answered back: I came down to change to sport bra, you know, women need it when exercising, men can never understand it since you don't have such experience, you know", now I want to see how his smile changing, "wow, I see", he just answered and buried himself on his email again.




But well, does woman really need sport bra when exercising?
