If you've been feeling a little down then you may want to forgo your treadmill run for an outdoor run. This is because past research found that those of us who run outdoors can be less depressed, anxious, hostile, and fatigued. Not to mention, outdoor runners feel more invigorated after than before the run. While a treadmill run is still great for your physical health, mentally, it may not do as much.
This is really interesting to me as I can totally relate. Granted I usually feel really good after a run on the treadmill; I do feel really good and pretty darn pleased with myself after a run outside along the water. What about you guys?
