Calories per hour, walking on a treadmill?

[JohnE798506]

Assuming I walk on a treadmill at a constant speed for 2 hours.....will the second hour of walking burn:

1. the same amount of calories as the first hour
2. more calories than the first hour
3. or less calories than the first hour?

If you walk on a treadmill at a constant speed and incline, you’ll burn about the same number of calories in the second hour as in the first hour.

After the initial warm-up, your body settles into a steady state where energy use remains fairly consistent. Unless you change your pace, incline, or start to fatigue enough to slow down, calorie burn doesn’t meaningfully increase or decrease in hour two.

For anyone focused on fat loss rather than just calorie numbers, combining steady walking with proven lifestyle habits can make a bigger difference. These practical strategies are well explained in weight loss tips guide that actually work.

Many fitness watches give you a good idea of this based on your stride length.  But I’ve noticed when I’ve walked in the neighborhood, not a treadmill, my pace is not always the same.  Sometimes slower, sometimes faster.  I would imagine based on your criteria you gave it should be about the same.  However, usually when someone first starts they have more energy and tend to move at a good clip, unlike the second half where they tend to lag a bit as your muscle fatigue creeps in.
