The Scorpions - No Pain No Gain
A little motivational workout music.NO PAIN, NO GAIN
If you want a serious edge... to crush your enemies, have them driven before you, and hear the lamentation of the women, then that really is true.
Champions dominate in training so they can dominate on the field and in the ring. Rocky got it right, and continues to be an educative model for champions.
(Incidentally, I have been a champion before, in a field of thousands, and I will be again, when the time is right...)
p.s. I want to make a Rocky spinoff using this song for a training montage. :)
