Humans in micro-gravity suffer from Ca loss and muscle atrophy, efforts are made to prevent it by means of physical exercises and with medicaments. The tread-mill and exercise bike are just two most frequently used examples. This can and should be widely extended, and in such a way as to mimic as close as possible the normal loading of the muscles and skeleton which we experience here on the earth. Special very light weight active harness is proposed which monitors the body loading. This is accomplished by means of computer aided monitoring of muscle and bone loading systems. Using feedback it helps the crew to load their bodies and skeletons in the same way as it happens here on the earth. The active exercise mat with pressure sensors first creates a record here on the earth of all normal muscle tensions during exercise. In space the computer guides each exercising crew member to follow their earthbound training routine. High care is needed to select the best and most effective exercises which should demand least energy, yet providing the very best results. May I suggest the very best known to me kind of comprehensive exercises: Yoga. Doing it on the Earth you need next to none special training equipment. Our body is in principle all we need here to do Yoga exercises on the Earth. Integral part of Yoga exercises are abdominal breathing exercises, which can slow down the breathing rate even threefold. This improves the oxygen and CO_2 exchange and massages all internal organs around the clock, helping the adept to stay fit and also keeps their minds steady and calm. Yoga exercises should be mastered already here on the earth, providing the crew with much greater tolerance to micro-gravity. In Yoga we acquire the tolerance not only to zero gravity but also to "negative" gravity: as it happens in all inverted positions. This should help the astronauts to be more tolerant of the half way only step into "zero gravity". Weightlessness state provides us the ultimate in perfect relaxation when asleep or awake. We have to check in space if we can thus diminish the use of medicaments or even eliminate them. Slow Yoga exercises decrease also the amount on food required because life is not so energy demanding in space as it is here under the earth's gravitation. We can stay lean and healthy with such static yet most effective physical exercises. In addition it gives us for free a vegetarian life style, just another benefit so useful in space travel.
