Treadmill at 12 per cent incline, 3 miles an hour, 30 minutes — 12-3-30 — a routine Lauren Giraldo posted in 2019 and re-posted on TikTok in 2020, after which every gym's treadmills were occupied by people walking uphill at the same speed. The record's entry for the workout that is three numbers.
A commenter asserted 12-3-30 burns more fat than running. The record notes it burns more than the sofa, and leaves the rest to the treadmill.
The record notes 12-3-30 is walking briskly up a hill, that the hill is imaginary and the walking is real, and that this is a fine thing to do.
What does it mean? Write it the way you would say it out loud.
