(CBS) - Researchers at the University of Copenhagen say finding the energy to keep exercising may all be in our head.  When we work out, the brain releases the chemical serotonin - signaling the muscles to keep going.

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