Abstract: A personal physical conditioning system, for a single, full-size human subject, has a sealable chamber that is configured to allow entry therein and occupancy thereof by the entirety of the single, full-size human subject and to allow the subject to exercise in a standing position using an item of physical conditioning equipment entirely contained within the sealable chamber. The system also has a ventilation system, including a pump, operable to change air in the sealable chamber and to establish, within the sealable chamber, a desired non-zero air pressure level of less than 1 atmosphere and down to pressure conditions substantially equivalent to an elevation of 25,000 feet above sea level. Related methods are also provided.

Abstract: A personal exercise apparatus that allows simultaneous simulation of mild to high altitude environments with algorithmically driven environmental stressors that may be pre-programmed or personally developed via physiological feedback during training. Additional stressors include an ability to transiently alter pressure in a chamber of the personal exercise apparatus at variable frequencies and amplitudes with a range of changes with an option of random pressure oscillations designed to personalize training programs. The additional stressors further include small variations in inspired CO2 levels and temperature allowing individuals to simulate breathing and temperature conditions in preparation for desired environmental conditions.
