Why does this 20-minute no-equipment workout work? It’s all about EPOC (excess post-exercise oxygen consumption). When you push hard for 45-second bursts, your body burns calories for hours afterward. Trainer Mike Chang confirms, “The 45s work/15s rest ratio maximizes fat burn by keeping your heart rate in the sweet spot.” *
Take Priya, a single mom from Austin. She lost 8 kg in 12 weeks doing this routine during her baby’s naps. “I’d blast through rounds between diaper changes,” she laughs. “My jeans fit better than pre-pregnancy!”
Key Science: HIIT triggers 25% more fat oxidation than steady cardio (ACSM).
