When I'm in the last few minutes of my workout, I find it most motivational when I have a kick-ass song playing and my own personal mind-push: "you can do this, these are but a few moments of your life that will shape what follows." I believe I have found one of
the most awesome almost-done-workout songs. When it popped up on Pandora, I felt like I was running away from or struggling to fight a monster.
Like a phoenix, burn today and flourish tomorrow.
Enjoy, and keep going!
