From by John P:

“I recently acquired a bad ass treadmill as part of an effort to get back in shape (more on that later), and I went searching for some USMC cadence MP3s to listen to while I run. They were harder to find than I thought they would be, so I figured I would share them here in case anyone would like to hear them.

These work songs are sung while a platoon is running in formation and let me tell you – they are motivational. When you hear 80 sets of boots pounding the ground in unison while 80 Marines sing cadence it is a site to behold.“
