Final answer:
The training strategy that will confer maximal improvements in performance is live at altitude, train at sea level. When living at altitude, the body produces more red blood cells to compensate for the lower oxygen levels, which can increase endurance. However, training at sea level allows the muscles to work harder due to the presence of more oxygen, which can improve performance.
