Live high, train low theory

The "Live high, train low" theory suggests that athletes live at high altitudes to naturally boost their red blood cell count, which improves oxygen-carrying capacity. However, they perform their intense training sessions at lower altitudes where oxygen levels are higher, allowing for better performance and recovery. This approach combines the benefits of acclimatization to altitude with the ability to train intensely, ultimately enhancing endurance and athletic performance without the drawbacks of exercising in low-oxygen conditions.
