A innovative resistance exercise system that helps preserve an astronaut's bone density, checks muscle atrophy and helps retain postural and gait stability during space missions while increasing neuromuscular activation and enhancing sensorimotor integration is presented. This innovative system comprises of a tight suit that covers the upper torso of the astronaut—from the top of the head to a little below the waist with magnets or electromagnets placed towards the lower end of the suit. When worn by astronauts on a magnetic or electromagnetic flooring (such as a treadmill's floorboard), a force of attraction is exerted on the magnetic end of the suit to create a downward pull that would be spread by the suit onto the muscular and skeletal systems of the astronaut right from the top of the head down to their feet (thereby also loading the vertebrae which extends into the neck region), as the astronaut seeks to keep his / her upright position. The suit may be used in combination with an internally ridged sole directed towards the plantar surface of the feet to stimulate the somatosensory receptors in this plantar surface of the feet. Prior methods of using chords to keep the astronaut in place on a treadmill restrict ease of movement, take a lot of time and do not load the head-neck region. The invention preserves the astronauts' good health longer and helps them function safely and efficiently in space or in the hypogravity of the Moon or Mars.
