Denmark - Researchers at the University of Copenhagen say finding the energy to keep exercising may all be in our heads. 

When we work out, the brain releases the chemical serotonin, signaling the muscles to keep going. 

But a new study finds that once a certain amount of serotonin builds up, the brain tells the body to stop.  That's what triggers a feeling of exhaustion.


Doctors say this new understanding of how the brain talks to the muscles may lead to better treatments for fatigue and even stroke patients.
