Answer: When you get out of breath while exercising, you’re not taking enough oxygen to your muscles, creating an oxygen debt. The muscles then create a toxin, which makes them cramp or hurt. When you stop exercising, you breath deeply, bringing more oxygen into your blood supply and removing the toxins.
