Any irregular chest pain experienced during exercise should be taken seriously. Chest discomfort can be indicative of a heart attack or angina – a blockage in the blood vessels of the heart that reduces blood and oxygen flow to the heart. Not all chest pain is the same, it can feel like burning, stabbing, tightness, or achiness. If you're experiencing chest or heart pain when you work out, you should talk about it with a medical professional right away.
