Sea level hypoxic training is altitude training without being on a mountain. You are exercising, resting, or sleeping in an environment made up of less oxygen than that at sea-level (21%) in order for the body to adapt to the lower than normal oxygen levels.
The beneficial physiological outcomes of adapting to low oxygen including enhanced endurance, energy, cognition, strength, and body composition.
