I have learned to love running and now actually crave the motion. For me, running is equal parts mental maintenance, cardio workout, and booty control. Nothing works my legs like running, and running uphill has become my favorite way to tone my backside.
When it comes to your favorite form of cardio, it looks like most of you agree. FitSugar readers voted running the most popular form of cardio in 2009. One reader calls running "nature's antidepressant," and I couldn't agree more. Working out on cardio machines is your second fave, with cardio classes close behind. Whatever you do to get your heart rate up, just keep on doing it. For more running inspiration, be sure to join RunningSugar.
