Drumming as a Sport: 13.3 Miles Per Show
At 1:45:58 · chapter starts 1:45:10
The conversation about drumming's physicality reaches its most concrete moment when Tommy reveals an experiment he ran years ago: he clipped a pedometer to his shoe during a 2-hour show to find out how far he actually moves. The result stunned him — 13.3 miles. That's the answer to the mystery he'd been wondering about: why does he weigh exactly the same as he did in high school despite no strict diet? He sweats out every calorie on stage. Joe draws the parallel to Travis Barker — same deal, same physical build — and marvels at the cardio demands. They conclude that drumming is unambiguously the most athletic discipline in music, with nothing else even close.
Playing drums upside down means gravity works against you — your arms need 3x the effort to strike, pedals fall open, hi-hats go slack. Tommy Lee had to add springs to keep everything in place. By the time the Crucifly roller coaster returned to the stage, he needed oxygen.
