I don't do any of the things people typically buy sports bras for. I am 50 years old and my knees hurt all the time and I'm a little chunky, so the whole running, jumping and bouncing thing is not something I am interested in.  I could start an earthquake. People could die... or laugh themselves into hyperventilation induced comas.... but I do work.  I have a small farm and I put up fence, build trellises, wrestle a milk cow, haul hay, much stables, dig holes, haul rocks, and all that other fun stuff.  This is sweaty work that often requires a lot of bending, stretching, contorting and other "activity" type things.

For this kind of thing, especially in the summer, sports bras are the way to go. But sadly, most sports bras seem to think that "support" means "smash those puppies into the ribcage, they won't move".  That is not a good thing. Nobody likes that. You'd think the bra building people would realize that.

FINALLY though. Found a bra that gives support, that breathes and is comfortable and doesn't feel like punishment to put on.  You should totally get some.
