This song is great for getting motivated because in addition to its steady, building beat, the very lyrics of the song embody what a lot of us need during our workout, that push to continue. "My body tells me no, but I won't quit, 'cause I want more..." The chorus alone is enough to give you that extra push you need! It's a great song to have blasting when you're trying to run off your stress on the treadmill or do that extra set of pushups. In doing a little research (and by research, I mean Wikipedia) it turns out the song actually came about due to the band letting out their frustrations during a particularly challenging time. That message definitely translated through and made this song a great motivational jam to turn on when you're ready to really work!
Sidenote: It doesn't hurt that this song was used in one of the very first episodes of the show "Teen Wolf" on MTV (Don't judge me!), so every time I hear it I can't help but picture a super hot, buff lacrosse player/werewolf working out and getting fit, which is great motivation!
