I took an improv workshop with some super-special-top-of-the-line improviser a couple of years ago. He had us all walk across the stage to teach us how to create a character with just our bodies, but initially, we walked in our normal fashions. Apparently, I am a “feet-first” walker, and I walk pretty quickly. Part of it is because I live in NYC, and part of it is that I was so much smaller than the other kids growing up that I had to walk fast in order to keep up with my longer-legged buddies, who just seemed to lope along.
At the workshop, some walked knees-first, some were hips-first, some chest- and some head-first. When I was on stage and wanted to create a “sexy” character, I had to consciously remember to put each foot ahead of the other one, like a runway model, in order to get the same hip swing like I do in stilettos. To walk that way is very hard in flats and trainers. My arms remain at my sides and don’t swing.
