A consumer based novel personal exercise apparatus that allows simultaneous simulation of mild to high altitude environments with algorithmically driven novel additional environmental stressors that may be pre-programmed or personally developed via physiological feedback during training. Additional stressors include the ability to transiently alter chamber pressure at variable frequencies and amplitudes with a range of changes with the option of random pressure oscillations designed to personalize training programs. Additional stressors include small variations in inspired C02 levels and temperature allowing individuals to stimulate breathing and temperature conditions in preparation for desired environmental conditions.
