Do you burn more calories running or lifting weights?

When it comes to burning calories, your heart rate is much more important than what it is that you are doing.

If you can reach and sustain the same heart rate for the same amount of time you will burn pretty much the same amount of calories regardless of activity.

Usually running would get your heart rate up, and keep your heart rate up more consistently than weight lifting, so for the same period of time, running would burn more calories.

They are very different exercises because running is aerobic while lifting is anaerobic. Both should be included in an exercise plan though.

It has been said that 30 minutes of NON-STOP lifting burns as much calories as running a mile. Running a mile shouldn't take you much longer than 12-15 minutes. So imagine how many calories you would burn if you ran for 30 minutes instead of lifiting. If you plan on burning calories and not building muscle, i would go with running.
