Amazon sells the whole “Run to Cadence” series put out by Documentary Recordings. These are recordings of 40 minute call-and-response chants by drill instructors and the grunts as they run in formation at 115 beats a minute.
I like to use my Airborne Rangers recording as a procrastination-buster when I have to tackle a disagreeable task around the house. I did not serve in the military, but when this tape plays in the background, I “fall in,” get pumped, and get the job done. The momentum stays a while.
