As human beings we exist (and have evolved within) a gravitational field. Most traverse their entire lives unaware of this fact in its practical and/or theoretical basis. External martial arts are the product of young people using their will-power to move their torso and limbs through this gravitational field in an inefficient but useful manner which sees the generation of a great force (only at the highest levels) which is far beyond the level of energy expenditure used to manufacture it. To achieve this the cardiovascular system must be made efficient (through running), whilst the bones, muscles, ligaments and tendons must be 'toughened' through regular usage. The mind is strengthened and focuses through repeated arduous training and familiarisation with the corresponding (physical) pain. The mind learns to use the body very much like a 'slamming door' with no regard to the state of the inner body or the health of the inner organs. At the external level (which must be mastered), the physical body is 'forced' through the gravitation field and it is the resulting 'resistance' which can generate substantial force. This type of power is entirely dependent upon the body being at a continuous peak of physical fitness - which is a state very difficult to maintain without the body structures being allowed regular periods of complete rest (so as to recover). A problem with this method involves illnesses and injuries getting in the way of achieving peak levels of fitness - and the ever-present problem of the ageing process. Within ancient China, the external training for combat could produce confident and solid soldiers in around three-months of continuous and systematic training. However, if an individual survived both the training and the combat experience on the battlefield, then what? The ancient Chinese understood that with age came both enhanced understanding of reality and a much more subtle appreciation of the human body and the environment it inhabited. This is how 'internal' training was established often hinted at by Confucian and Daoist ideology - and later Buddhist thought. This involved the mind being trained to be aware of how gravity operates through the bone-structure of the skeleton. The ancient sages realised that without any muscular effort (or corresponding psychological angst) whatsoever, gravitational 'force' effortlessly drops down through the centre of the bones (stimulating the bone marrow in the process), and enters the ground ('rooting' the practitioner) before a 'rebounding' reaction occurs which sees a corresponding 'force' travel back up through the centre of bones to the top of the skull. This process occurs simultaneously without interruption, contradiction, or paradox. It only ceases when the human body leaves its familiar gravitational field. (Chinese Cosmonauts have been experimenting in the zero gravity of space to see if a modified Taijiquan can assist in the preventing of soft bones during long space flights). The internal practitioner trains their mind to become aware of this free reservoir of energy and to propel it throughout the body, regulated by the martial techniques of Taijiquan, Baguazhsng/quan and Xingyi, etc. This means that without having to move to generate power (as in the external model) power is immediately available 'here and now' whilst standing on the spot. As virtually no undue effort is required to produce it - this power is far stronger, penetrative and destructive than its external variant. The nature of internal power is like a spinning vortex whilst remaining free of any contrived violence. This is deployed in combat not through any form of aggression, but rather as a matter of gentile timing and positioning. Providing this skill has been thoroughly learned, then there is no need for any undue effort. At the highest levels, quite often it is the case that elements of the external and the internal are deployed simultaneously without contradiction and allows from the higher ground of the internal perspective. This is why old Masters with considerable health problems are still unbeatable in the training hall - even days or hours prior to their deaths! I wanted to make it clear that by mastering the internal method - poor health due to age, injury or genetics is transcended. Where many cannot detach themselves from their physical characteristics, the internal Master 'has already left' so-to-speak. Either way, and whatever the case, there is only love in the process with the internal giving the maximum chance for a possible recovery of poor health - even if it is unlikely. Seated meditation, by the way, is essence 'internal' and this is why the old Masters practiced it. Life can be preserved and prolonged even within illness and poor health. For some people this is needed because they have unfinished business to complete.
