How Many More Calories Do You Burn Walking Uphill?

It certainly feels like you are burning more calories when you walk uphill or add incline to your treadmill workout. But how many more calories are you burning by walking uphill? The answer comes from two sources: research measurements for metabolic equivalents and equations used by the American College of Sports Medicine (ACSM).

Burning More Calories Walking Uphill

Research in metabolic equivalents uses actual measurements of the calories expended by people walking uphill at a brisk 3.5 miles per hour with those walking on flat, firm ground at the same speed.

The difference was an increase of calories burned by 60% or by an additional 48 calories per mile for a 150-pound person. On flat ground, that person would burn 80 calories per mile. This research of metabolic equivalents (MET) is used in walking calorie charts and some calculators.

The second method uses the equations from the "American College of Sports Medicine's Resource Manual for Guidelines for Exercise Testing and Prescription," which shows:

  • For every 1% of grade, you increase your calories burned by about 12% or about 10 more calories per mile for a 150-pound person.
  • By the time you are at 10% grade, you are burning over twice as many calories per mile.

This is why hiking is often listed in calorie calculators as burning many more calories per mile than walking.

The Incline on Hills and Treadmills

The amount of incline makes a big difference. Not all hills are alike—they have different inclines (percentage grades). On a treadmill, you can accurately set your incline at 1%, 2%, etc.

When walking outdoors, you need to use a tool such as to map out your walks and see what the incline really is. A 5% incline will really get your heart rate up and you'll likely be breathing hard.

What Goes Uphill Must Come Downhill

Unless you are on a treadmill, what goes up must come down. Do you lose all of that extra calorie burn because you were going downhill for part of your walk?

No, MET research shows that when going downhill you only burn 6.6% fewer calories per mile than walking on flat ground. That means burning 5 fewer calories per mile for a 150-pound person. Overall, by adding a 1-mile uphill walk followed by a 1-mile downhill walk, a 150-pound person would burn 43 more calories than they would have walking those 2 miles on flat ground.

Can You Trust the Calorie Display?

The numbers for calories burned as shown on your treadmill display and those counted on your fitness band or heart rate monitor probably don't match each other, particularly when walking on an incline. It can be difficult to know which of them, if either, is most accurate. In every case, setting an accurate weight in the app or display will help it calculate more accurately.

Some fitness bands and smartwatches use your heart rate and an altimeter to know when you are going uphill. These devices may use this to refine the calorie estimate. Others don't have these functions and may not know when you are going uphill or downhill. The treadmill, however, has the incline data, which hopefully influences the calorie data it presents.

Adding Hills to Your Walking Workouts

You may already have hills on your usual walking route or use incline in your treadmill walking workouts. But do you use good form, posture, and technique?

How to Walk Uphill

Use this uphill walking technique for those climbs:

  • Don't raise your knees too high.
  • Keep your torso over your hips without leaning excessively either forward or backward.
  • Shorten your steps and try to maintain the same pace.

How to Walk Downhill

Walking downhill can place a strain on your knees, as those with knee problems probably already experience. You should learn good techniques to help protect your knees on the downhills:

  • Don't lean back. Keep your hips over your knees in an upright posture or even lean very slightly forward for better stability.
  • Keep your knees slightly bent at all times on steeper slopes.
  • Your stride will naturally elongate going downhill, which will help you brake while still moving faster than usual. If you find yourself going too fast, shorten your stride or slow down your steps.

A Word From Verywell

Hills add a new dimension to both treadmill and outdoor workouts. Use them to add extra intensity to your walk so you can burn more calories over the same amount of time and distance.
