In April 2007, one of my Feldenkrais colleagues, Ryan Nagy, posted a video on YouTube titled, "What is Feldenkrais?"
It is a wonderful video, 10 minutes long.
It was made early this year by another colleague, Frederick Schjang, who teaches in NY and worked for years as a fitness instructor before taking the Feldenkrais training. Frederick intended that this video be a "high-tech calling card" so Feldenkrais Practitioners could get jobs teaching in health clubs. So far, it has worked for that, and more!
