Bodywork consist of shaking, rocking, hands on work and gentle manipulation of a body.
Rotating the joints while being passive helps relax and release a lot of muscle tensions around the body. It also lubricates the joint in question. It is often easy to gain more space and movement range with gentle turns and rotations.
Shaking and rocking releases the tension of muscles, sometimes it also “rearrange” them.
Hands on work is the most gentle work of all. Basically the worker is just listening clients physicality and the reactiions with his hands, allowing the clients physicality to rearrange itself. The work often gives deep relaxation.
When doing a bodywork often all of these methods are mixed depending what is necessary to gain relaxation of body and more space inside of joints and muscles.
