Treadmills as cardio pieces of fitness equipment do their job very well. They give you probably the best workout for burning calories. Using a treadmill takes a lot of effort and if you're trying to lose weight then they're ideal. They burn a lot of calories per hour. The actual amount varies due to a number of factors.

What affects how many calories per hour you burn

How big you are plays a factor. Your weight makes a big difference to how many calories you burn in an hour on a treadmill. Someone who is 180 pounds will burn more than someone who is 130 pounds. This makes sense because it's harder to move a heavier weight and this counts on a treadmill too.

Your speed plays a role. If you're running at 7 mph for an hour you're going to burn far more than if you're walking at 3 mph. Distance plays a part too but we can ignore that because we already have the time specified which is an hour. So speed and time determine the distance. An hour is a long time on a treadmill but is doable with practise and training.

Finally we have the gradient or incline. It takes more energy to go up a hill than on the flat. Therefore, if it takes more energy it's going to burn more calories. A large incline is something you shouldn't do for a long period of time on a treadmill especially an hour. It's bad for your joints so if you want to make the workout harder then better to go faster.

How many calories you burn by walking for an hour

Walking for an hour on a treadmill may get a bit tedious but we'll add it here to show how much speed makes a difference. Hey, you might want to walk for an hour on a treadmill it's up to you. We'll take walking as 3 mph which is a brisk pace and a pace nearly everyone should be able to do.

  • Speed = 3 mph
  • Weight = 180 lbs
  • Time = 1 hour
  • Calories burned = 480
  • Speed = 3 mph
  • Weight = 130 lbs
  • Time = 1 hour
  • Calories burned = 347

As you can see the weight makes a difference of just over 130 calories in this example. These are on 0% incline, if we were to add an incline of 4% then the 130 lbs person would burn 398 and the 180 lbs 551 calories. An incline is something you can do if you're walking on a treadmill and as you can see it makes a big difference.

How many calories you burn by jogging for an hour

We'll take jogging as going at 5 mph. This is where it gets tougher to last for an hour on a treadmill. It will take some practise and training to jog for an hour but it's worth it if you're trying to lose weight. You'll burn plenty of calories and we'll take the example of someone who is 130 lbs and 180 lbs.

  • Speed = 5 mph
  • Weight = 180 lbs
  • Time = 1 hour
  • Calories burned = 744
  • Speed = 5 mph
  • Weight = 130 lbs
  • Time = 1 hour
  • Calories burned = 537

We wouldn't recommend you using an incline for jogging or running except maybe 1% to make it like running outside. Using a higher incline for a long period is not good for the feet and legs.

How many calories you burn by running for an hour

This is where it gets really hard and we're getting into athlete territory. We'll do our calculations of running at 7 mph. You'll really struggle at this and find nearly impossible to do it for an hour as someone who weighs 180 lbs. But we'll still give the results to show what's possible and for completeness. Some may be able to run faster for a long period.

  • Speed = 7 mph
  • Weight = 180 lbs
  • Time = 1 hour
  • Calories burned = 1006
  • Speed = 7 mph
  • Weight = 130 lbs
  • Time = 1 hour
  • Calories burned = 727

All calculations here were found by using this fantastic website. We recommend you having a play with it and you can enter your own exact weight and find out how many calories you can burn depending how fast you weigh and go. You can enter any time or distance to complete the calculation.

It takes 3,500 calories to burn 1 pound of weight

So as you can see if you regularly walk, jog or run for an hour outside or on a treadmill you'll be well on your way to reaching your target weight. Not only that but you will make yourself incredibly healthy and will gain many more health benefits because you'll be doing exactly what the CDC recommends.
