I often find that half the battle of going to the gym is motivating myself to get there. One easy tip I do to get myself motivated is to turn off the tv and turn on some music. In the mornings, when I am getting ready to go to the gym, I turn on music that I can move to as I get ready. This way my mind and my body are gearing up to getting in a good work out. If I am planning on working out, I don't want to be curling up on the couch and starting a Lifetime movie since that would be a definite work out killer.
Fit's Tip: Low impact dancing gets your heart pumping and burns calories (150 calories in half an hour)... what's a better addition to your work out than grooving to some tunes while you get in gear?
