She replied that she took a bar & lifted it up & down (barbell curls) which freaked the interviewer out.
This may sound ironic or stupid, but I think that's one of the most fundamental things to know about training.
For example: If you want to work lats, hang onto a bar and pull yourself up. For chest, lie down and push something in a straight line upwards. So simple, you don't even need names for the exercises! I mean, if everyone went and learnt something about how to stretch and contract each muscle, you wouldn't need any fancy names or anyone to teach you how to train, as you'd simply go by what contracts the muscle.
Agreed, it's easier to open a book of training exercises and go by that (hell, it's what I do), but I'm just saying that BBing doesn't need to be fancy names and things. You just find what works, by doing whatever it is.
