Running with empty hand is a better plan Running used to be a simple effort. All you needed was a shirt, shorts and shoes. Now, it is far more complicated. We are a nation of accessorizers,even in our exercise. We bear water bottles, music players, phones and activity trackers. And although we use them to make our runs easier, here is the bad news: They could be slowing us down. To realize why an MP3 player or a water bottle might hinder your progress, a brief lesson in bio mechanics is in order. Your upper body plays a serious role when you run. (Thats why the bad guys never get far when they escape from police custody in handcuffs.) Both the arms and the trunk come into play, helping the legs lift the body and working together to create a smooth stride. Good running form starts in the hands. They should be relaxed and comfortable. If you are holding something, you will create tension and imbalance in your upper body. No matter the object -- a water bottle, an iPod, a set of keys -- holding something alters your form and makes you exert more energy. And the more effort you expend, the faster you will tire. To see how this happens, equip one to grip a bottle and move your arms as you would while running. Even without the bottle, your forearm muscles contract, or try running with your fists clenched. That tension in your hands creeps to your forearms, then your upper arms. This makes shoulder rotation more difficult, which inhibits your leg drive.
