The barbell I use right now is a womens olympic bar(lol).

I know the bar weighs 15kg/33lbs instead of the standard 20kg/44lbs bar.

I just thought maybe there is some other differences between the bars. The women's bar is shorter, but is it different in terms of flexibility or anything else.

Which leads to to my next point. What are the different bars available? I mean just the straight barbells. I keep hearing about eleiko, texas, oakie bars and all that but don't know how they differ from one another.

I see loads of YouTube videos of bouncing bars that bend alot. Is this to do with the actual bar or are they simply not pretending(because the bar is bending)?
