Relaxing massage usually entails working with the client on a couch. Each session lasts for one hour, although 30 and 90 minute treatments can be given. The practitioner uses four main techniques or “movements”. These techniques are effleurage (a stroking or gliding movement), petrissage (a picking-up and kneading movement), friction (a pressure application) and tapotement (a percussive or striking movement). Massage is excellent for muscular and physical relaxation, aiding venous return of blood to the heart, improving lymph flow and relieving congestion.
