Trainings begin with an emphasis on ATM verbally directed floorwork. As the Training progresses, and the students learn about the Method and their own bodies, the emphasis shifts toward learning FI, the hands-on style of Feldenkrais work. Some people only take the first 2 years of a Training, which covers most of the ATM work. This option results in most of the personal growth (next paragraph) but does not confer certification as a Practitioner.
A Feldenkrais Training is well known as an intense personal growth experience. People often "store" their emotions in their bodies. These "somato-emotions" take the form of changes in posture and movement patterns due to increased muscle tone in the shoulders and other places. A common result of Feldenkrais work is a relaxation of these habitual patterns of holding the body (you learn new postures and movement patterns), and the emotions that are associated with the old, chronic holding patterns are released to consciousness. Some people experience a Feldenkrais Method Professional Training as emotionly wild and with rapid and profound personal changes, but most people seem to experience noticable but more subtle and gradual personal changes.
There are different formats for Feldenkrais Method Professional Trainings. The traditional format (used by Moshe) involves meeting once a year for 4 years, each session lasting about 2 months. Many Trainers are breaking that up into 2 or 3 smaller segments which may fit better with your schedule. The 2 month trainings are said to be emotionally more intense than the spread-out versions.
People can make up lost time in a Training, or join a Training late (up to a year late in most Trainings), by making up the lost time. This can be done by attending another Training or by getting tapes of the ATMs done during the missed time. I personally wouldn't use tapes to make up a Training. For one thing you have to pay for the Training time that you missed and that's very expensive for tapes! My other reason is simply my opinion that live Trainings are better than tapes.
Trainings typically cost about $3,300 per year, plus housing and food. It can be an expensive undertaking! But on the other hand, there is nothing like a Feldenkrais Method Professional Training for personal growth and a new career, all rolled into one!
There are many highly qualified Feldenkrais Method Professional Trainers worldwide. Based on my personal experiences I can recommend three excellent Trainers:
