Coming from a former personal trainer, I kind of see where he's going here. Words like "toned" and "build muscle" etc are sometimes different for everyone, yet a picture tells a thousand words. Kind of like at a hairdressers. Just be sure and pick a body that is the same body type as yours or you're just wasting your time. I'd love to look like Cathe but no personal trainer will ever shrink me 3 inches or get rid of my hips to make me like her. I'd have a much better chance bringing a picture of say, Cedie, although her roadtrips pictures are making me rethink that! My guess is the personal trainer wants to see how much muscle she is wanting to build. Just a guess! Good luck!
