Your eyes should be focused straight ahead of you. Looking off into the distance. Just find something on the back wall and focus on it.

WARNING: There will be bright lights aimed at you! Do not try and focus on a light unless you want to go blind and walk right over the ledge of the runway, because all you can see is the after image of the light bulb.

Don't gaze and gawk in every direction. Keep your eyes focused straight ahead. Never look down at your feet or scan the audience. Focus your gaze on an imaginary point straight off in the distance.

A lot of models, when learning runway modeling, tend to swing their arms way too much. Your arms should only swing as much as your body makes them.

With men and women it is a little bit different of a swing. The reason for the difference is how a man takes his steps. His step will cause his whole arm to swing more while a woman's steps will cause her arms to swing more from her elbows down. Next time you watch a model runway modeling, watch and see how their lower arm is doing most of the swinging.
Tip for WOMEN: Concentrate on keeping your upper arm in close and somewhat tight to your body. This will ensure that only the bottom half swings.
MEN: All you need to do is just let them swing naturally. Don't assist them at all.Here's why: Say you are walking down the runway with your arms at your side. Then someone for a fashion magazine take an awesome picture of you.
Now this is a good picture! Everything looks perfect, until they look at you hands! Why? Because you, like most people, had your fingers curled in and up slightly.
So what's wrong with that you ask? You have no fingers!!!! At least in the picture it will look like you have no fingers! Like they all got chopped off!
Always remember to have your hands open with your fingers nearly totally straightened. Not totally straight (you don't want to look like a robot), but out enough to be visible.
