1. Hatebreed - Perseverance
"The ultimate meathead anthem; Hatebreed fucking rocks. You already know that, but this song was obviously written about being pinned under heavy weight. It takes my mind to a place where I can do anything through "discipline and determination" -- FUCK YEAH."
2. Pantera - A New Level
I don't know if Phil Anselmo fucks with the iron, but maybe he wrote this song for a friends who do. "unscarred by trials" -- I feel that.
3. Terror - Overcome
The title makes it clear why this song can be motivating. Terror is hard as fuck, and this song is about doing whatever you want and not giving a fuck.
4. Hatebreed - Proven
Another Hatebreed song, duh. This song comes right out the gate just beating your ass by just repeating "you want to see me fail, you won't get your chance"
5. E Town Concrete - Time 2 Shine (Found on Spotify playlist only, not available on Rdio)
This song may not be about lifting weights, but its about doing whatever the fuck you want and taking what you never had. Plus it sounds fucking hard.
