I don't know that she wants them bigger. She already feels they get in the way of some every day activities. She's a golfer and does CrossFit which can be difficult with big boobs.
When she's doing some of the activities the bar hits her in the boobs. She says it is a bit uncomfortable.
As someone who does CrossFit, I'm amazed that she can do some of the movements at all. Kipping pullups must create a bit of strain, as I would imagine her boobs would be a bit uncooperative. And the clean and snatch are no doubt what you're talking about re the bar hitting her boobs. We strive to have the bar path as close to our chest as possible, so she's no doubt had to modify her technique to get the bar path out beyond her boobs. It wouldn't surprise me if she uses a compression bra or similar arrangement to keep her boobs smooshed so she'll be less inclined to clip them. And running... again, she must do something to help lock those puppies down.
My hat is off to her.
