I had no clue!

You'll learn correct body mechanics in a good school. Some styles tend to be rougher on your body than others. I do Zen Shiatsu and it's like doing Taiji, using as little muscle as possible.

I am a licensed massage therapist as well as a registered nurse. I have practice massage therapy since 1986. Have practiced nursing since 1996. I have a private massage therapy practice and work as a nurse in the hospital setting. I practice swedish massage but over the years have incorporated Shiatsu massage within the framework of Swedish. I know Nurses that practice Theraputic Touch. It is not massage but a form of energy medicine. Also know one who is a Reiki Master. I have attained the second level of Reiki. Felt no particular calling to pursue the master level. I also have studied and practice reflexology. I don't find Swedish Massage physically taxing. To the contrary. I find it quite relaxing.
