Always bust this out to put me in beast mode. Did that tonight and now I feel like an ass haha. New girl at the gym was smoking hot and checking me out every chance she got, but when I'm in beast mode, nothing but the weight matters and when on the sauce in beast mode my mind goes to overload... everything turns red and I get this evil grin going.
So... you want beast mode? This song will do it for you.
