Hi Poppyangel (love your user name btw), I would highly recommend you train in hands-free or no-hands massage, Lomi Lomi also uses the forearms rather than the hands.
The reason why I recommend these courses is if you are doing a lot of physical massage, and you are currently offering 4 types, you run the risk of RSI or carpal tunnel.
I read somewhere that I massage therapist has a 7 year shelf life then either burns out or has health issues like RSI, fibromyalga, etc. With that in mind, I made sure that I also trained in treatments that gave my hands a rest, such as reiki, crystal healing, hopi ear candles.
I've been trained in hands-free techniques, which shows you how to massage using your body weight, your forearms and knuckles, also how to do stretches using these techniques. If my hands start to tire I implement my hands-free techinques.
so my advice would be to train in that, and also add a few other treatments that are not massage related. HTH hun.
If you pop onto the guild site, you will find courses near you. (the link is in my signature).
