A lot of talk about expensive bars here, for a casual home trainer who wnats a $200 bar
Not sure how people bend these bars unless they are mis treating them, My most expensive bar is $55 and I have dead lifted over 180kg with it and it gets used every time I train and it's still perfectly straight.
180kg is not a lot by some people here, but it's still a bit, even if I exceed the 180kg in the future I don't think the average home trainer requires a $500 plus bar unless you are competing and getting quite serious about your training.
I think it's more want than need to be honest.
