yes, I have just done a course in it, I am still promoting it, but the response has been really good, a lot of my existing clients have expressed an interest.
I am really glad that I did the course as I felt the stomach area is skirted over in a lot of the massage treatments.
I am still marketing it - getting it out there so can't tell you what response I have as I've only been doing it a month. So far I have done about 6 and had a very good success rate (See above post).
I also would point out that some clients would need to see you more than once in a week, so the potential of packaging this is good too.
