moving of person

How should I move a 3d person model in openGL ? I have just idea that i could load ase files of each part of the movement and i would just change the parts. But i think that it is not very effective way.

a good way is to load a model and use Skeletal Animation a tutorial on it is at http://rsn.gamedev.net/tutorials/ms3danim.asp, although this is abit much for a beginner.
