One of the most popular exercises at the gym is the treadmill. Whether you’re running or walking, it’s a great way to get your heart rate up, get your body moving, and for many people, a great way to burn calories.
But however you use a treadmill, there’s one extremely simple thing you can do to dramatically intensify your workout: incline it!
If you’re an outdoor walker/runner, this is the equivalent of going uphill instead of over level ground. There are many physiological differences in walking along an incline versus on level ground, but what does physics have to say about it?
Normally, if you’re on level ground (or a level treadmill), you stay at the same level in the Earth’s gravitational field.
