Frequently asked questions

Does incline really burn that many more calories?

Yes — significantly. At a 5% incline and 8 km/h you're burning roughly 50-60% more than on a flat belt at the same speed, because the muscles must work against gravity. This is why incline walking is popular for low-impact calorie burn.

Is the 1% rule worth following?

Yes — adding 1% incline on a treadmill roughly compensates for the lack of air resistance during outdoor running, making the effort more equivalent to road running at the same pace.
