Here's a quick tip for anybody looking to shed lbs as a New Year's resolution. Upon waking in the morning the body has more or less processed all of it's blood sugars into glycogen/adipose.
This means any activity taken before eating forces your body to quickly deplete it's glycogen stores and begin turning to other sources for fuel. If this exercise is prolonged, but not destructive to muscle tissue, your body turns mostly to fat stores for energy. Pair this with caffeine to really get things moving.
