To name a few that have been on the rotation.
Celldweller's "Actions speak louder than words"
Rolling Stone's "Under my thumb"
Ministry's "Let's go"
Orbital's "Halcyon on and on"
Machine Head's "The blood, sweat, the tears!"
The best workouts are when you give it your all, blood sweat and tears so this song definitely fits the occasion.
search DJ BL3ND on youtube. his mixes are so energizing and keep me going through INSANITY workouts, love love love them, his mixes are the best thing ive found to workout to hands down! :)
