Those Colcci ads look a bit airbrushed.. I hate it when these companies do that.
I think Gisele's great body is down to discipline and exercise. If you look at her family, they've not all got her body - they're much more curvier, certainly some of her sisters - so you can't just put it down to amazing genes. She must eat well and exercise regularly. She says she's less of a gym person and more sport orientated - she jogs, surfs, goes horse riding, swims, plays volleyball and bike rides..... It makes sense her body's in the shape that it is.
