EPOC: Sprint Science
Released: 2026-07-01

Description
EPOC is the first sprint training app built around the science of the afterburn effect — the phenomenon where your body continues burning fat for hours after a short, intense sprint session.
Most fitness apps are built for athletes. EPOC is built for people who want to live longer, move better, and burn visceral fat — the dangerous deep belly fat linked to chronic disease. You don't need to be fast. You just need to show up.
THE SCIENCE
EPOC stands for Excess Post-Exercise Oxygen Consumption. Sprint training triggers a metabolic response that no amount of steady-state cardio can match — flooding your system with growth hormone, torching visceral fat, and building the fast-twitch muscle that keeps you powerful as you age.

WHO IT'S FOR
EPOC is for the fitness enthusiast who already has a routine and wants to add something that actually moves the needle on body composition and longevity. If you follow the work of Peter Attia, Dr. Sean O'Mara, or Mark Sisson — you already know why sprinting matters. EPOC puts that science into practice.
