In general all the blood, sweat, and tears are signs of a good workout — well maybe not blood, but you get the idea. There are, however, a few things that you should take as warning signs of something potentially more dangerous when working out. A few aches and pains are nothing, but here are signals that should raise a red flag:
- An unusually rapid heartbeat
- Experiencing a severe headache
- Having difficulty breathing
- Chest pain, chest pressure, and/or chest tightness
If you suddenly experience any of the above during exercise then it's a good idea to consult your doctor immediately as they can be a sign of heart disease, asthma, or just that you drank too much coffee before hitting the gym. Regardless, there is no harm in getting it checked out.
