“Why do we exercise? Some exercise for the health benefits. Some exercise to maintain a great appearance. Some are in it for mood elevation, stress reduction, relaxation, or endorphins.”

True! simple way to put it!
- Health benefits
- Image
- Stress reduction/relaxation
- Endorphins (bochemical addiction :)) = Mood elevation
Endorphins?

In short, one of the reasons you train is because of how it makes you feel on a “biochemical level”.
By the way, this is different than training for the adrenaline kick!
