Answer:
it's a bit of a trick question
Explanation:
W = distance X force
when the distance is zero, the work is zero. So when she holds the weight without moving them she is doing no work. But, to be fair, that's just the wording, what "work" means. she is actually producing a force, that is equal to the weight of the barbells, to hold them against the graviational force.
I really want to be able to say "It depends on the size of her chest.".
But it doesn't. As long as the barbell is motionless, no work is being done on it.
