Petrissage

The two main types of petrissage are kneading and wringing. These similar techniques are useful for deeper massage but only after you have warmed up the muscles with effleurage. Kneading can be used lightly or as a much deeper technique, while wringing is always a deep massage technique.

• Kneading: This is a deeper stroke than gliding. It milks the muscles of toxic waste products and helps to separate bunched muscle fibres.
  It is most useful on the legs, buttocks, back, and upper chest.
  Place both hands on the body with your fingers pointing away from you.
  Press into the body with the palm of one hand, pick up the flesh between your thumb and fingers and press it towards the resting hand.
  Release and do the same with the other hand, rhythmically squeezing and releasing.
  Use sufficient pressure to loosen the muscle, but always keep the comfort of the receiver in
  mind. Avoid putting pressure on the back of the knees and on any bony areas.
• Wringing: This is similar to kneading but your add a twist to the method, so you work on the flesh as if you were wringing out a towel. It is suitable for the shoulders and fleshy areas such as the hips and thighs.

This movement is used to release tension from stiff muscles, improve circulation and help eliminate metabolic wastes, and break down fatty deposits, so they can be reabsorbed by the lymphatic system and eliminated more easily.

Kneel beside the receiver and with your hands cupped over a limb, slide the fingers of one hand right over to the far side, while the heel of your other hand comes down on the near side.

Very similar to the wringing is the friction.
