For Beyond 50's "Natural Healing" talks, listen to an interview with Michael Grant White ( https://breathing.com/). He is a Optimal Breathing Coach, founder of My Oxygen Machine and Breathing.com. He teaches that during exercise, your muscles have to contract and work harder, which increases their demand for oxygen. The amount needed is much more than you are taking in. Your body first burns the existing oxygen in the red blood cells and when this runs out, the body turns to fermentation for its energy needs. Instead of using oxygen, the muscles convert glucose into lactic acid and this is when fatigue sets in. Learn from White about how to do oxygen-enhanced exercise that can leverage the body's already-existing system for oxygenating the blood before this happens. It is a scientifically proven phenomenon that's said to benefit the body by reducing the physical stress of exercise, accelerating recovery, helping you sleep, giving you more energy, and improving your metabolism.
