Hi

This is the way that I do it.

I often do this to keep the arms from going through the body when they swing back and forth while walking.

Go into the Animation Palette and select Shoulder.

Open the drop down Remove all the key frames for the shoulder Up Down movement after your starting frame.  I'm usually just moving them out from the body a little and keeping the rest of the movement so that the arms still swing but further out from the body.

If you don't want the arms to move at all, after your start frame just remove all the key frames for Shoulder, Forearm, and hand.

Not having any movement won't look natural so you should go back after removing all the movement and put some movement back in so that the arms move a little as the character walks.

If you shoot a mime, do you need a silencer?
