This describes the connections between different muscle groups.

Muscles do not act in isolation but as part of the whole person, connected via the bones, ligaments and other tissue. Any useful action requires use of many muscles.

The strength of a hand-shake is not dependent entirely on how well developed the biceps or triceps are, but also the shoulder and chest muscles and right down through the pelvis to the legs and how well anchored the person is to the ground.

A crane operating on a building site will not be capable of the fine movements required at its business end if it is not firmly anchored on the ground. The same is true for the human body. There has to be stability and therefore connectivity between the major muscles of the body in order to be physically anchored for any activity involving fine movement.

Muscles do not need to be well developed in size to have connectivity although connectivity is required in order to develop size.

The expressions 'get a grip on yourself' and 'pull yourself together' can be applied to the physical requirements of achieving muscular connectivity. The main focus of body grip is the chest, from which the greatest number of muscles capable of fine motor action are attached, namely those in the head and arms.

The essence of body grip is in the development of the inter-costal and chest muscles to produce connectivity that enables a full 'grip' of the body. While this may seem unimportant in itself, it has ramifications for all activities involving the body. Body grip is a skill that is developed from the earliest years of infancy along with posture. Well developed body grip reflects confidence, physical strength, assertiveness, physical attractiveness and so on.

Well developed body grip is a prerequisite for excellence in any skill. Further, good body grip involves connection to the ground via the legs and to the arms for fine motor movement.
