There's a lot to be said for being able to administer a complete body massage. Even if you don't need to make this a profession, which incidentally is extremely rewarding, you could use it as a tool to help rid your spouse or some family members of all kinds of aches and anxieties. There's a proper process to a complete body massage, and when done well, it certainly qualifies as an art.

You should start by creating an extremely proper mood for a message. Keep the room temperature comfortable and normal. If possible, you also need to light some candles and incense, while playing soft music in the background.
If the person you will massage has problems with modesty, then you need to keep a soft and clean towel handy. You'll also need oil to assist the message to go simpler. Any natural or baby oil will do, but if it's lightly scented it may be appreciated more.
The person being massaged will have to disrobe and lie back on the table, face down. If required, you can cover the bare buttocks with a towel maintained expressly for this purpose.
You need to begin the body massage with the upper chest. Put about a spoonful of oil on your hands and rub your palms together to warm it, remembering to replenish it regularly. Apply it to the side of the neck and working up towards the temples.
Next, you should concentrate on the backbone area, rubbing it gently in circular external motions. Knead the surfaces of the body softly but firmly, working your way up to the armpits and then the shoulders.
