#12‑3‑30

A new peer‑reviewed study testing the viral “12‑3‑30” treadmill routine finds incline walking uses a higher share of fat for fuel than a self‑paced run, but running still burns calories faster — and that difference matters for weight loss. The study, conducted by researchers at a US university and published this year, matched the two workouts for total energy expended and showed incline walking produced higher percent fat oxidation (about 40.6% vs 33%), while running required less time because it burned more calories per minute. This nuance matters for anyone in Thailand deciding whether to lace up trainers or step onto a treadmill incline for fat loss or general fitness (An Exploratory Study Comparing the Metabolic Responses between the 12‑3‑30 Treadmill Workout and Self‑Paced Treadmill Running) and has been summarised in recent coverage of the findings (Incline Walking vs. Running: Which Is Better for Burning Fat?).

Bangkok’s gleaming fitness centers and community health clinics are witnessing a quiet revolution. The viral “12-3-30” treadmill routine—30 minutes of walking at 3.0 mph on a steep 12% incline—has captured attention from Chiang Mai’s mountain-view gyms to Phuket’s beachside wellness centers. Now, groundbreaking research from the University of Nevada validates what millions of Thai fitness enthusiasts suspected: this deceptively simple routine might be the perfect alternative to traditional running.
