Today is the day to start that workout you have been longing to do, that run you keep talking about or that other sport activity you have been pushing forward.
Just put all things aside, and just initiate! Begin small, create realistic goals for yourself and stick to it. Just start with a 1 kilometer run, 2 pushups or 5 crunches. It doesn't matter where you begin, as long as you do it. Just train in the comfort of your own house, at the moments you want to.
