I don't know which advert this is, as I'm at work and the tube is blocked. However...
There is a Diet Coke advert (which in the UK is HEAVILY aimed at women) where four women are sitting on a hill in a park, and see a guy mowing the lawn (yeah, in a park) at the bottom of the hill. One of them rolls a can down the hill, which hits the guy's foot. She mimes for him to drink it, so he opens it and it explodes all over his shirt.
So naturally he takes off his shirt (muscly as f) and the women all gasp.
If that's not objectifying men, I don't know what is. Double standards OFCOM? MUCH?
