I agree with Erica.....there is no reason to overthink this. I do something similar. I've never had anyone embarrassed when they try to sit down backwards only to find they have to turn around. Keep it light and loose and you won't have any problems.

Samantha.....I have had people sit in the chair backwards so I could work quads, calves and feet. It's not that uncommon. You can also do pec work from that position.

If there is no one else there, there should be no need for embarrassment. If there is another chair massage practitioner, just point to the person in that chair and say gently that you can get at their back and neck better when they are positioned like that. Occasionally you will find someone who does not want to sit in the chair face forward. Just work with them that way.

As to language, it is amazing what you can get across with sign language!

I am a strong believer that lighter pressure gets more results - I teach practitioners how to incorporate myofascial release into chair massage. Instead of mashing into someone's traps, lift them the traps gently but firmly for at least 90 seconds. You might be surprised (and they will too!) at how well they soften. This works for all areas that you would compress too.

I'm starting a 100 hour chair course Sunday that will include working on people backwards, in wheel chairs and at desks. It's about myofascial release.
