I'm a huge proponent of using music in your workouts to help get you going.  Even on my most low energy, depressed days, when I'm literally dragging myself to the gym or park with a head full of self-talk like, "Just WALK for 15 minutes- you don't have to run or lift weights." If, when I get there, I put my ipod on, after a few minutes, I can't help but start running or working out harder.  Like
