Does exercise raise your metabolism so you burn more even at rest?

Short answer

Yes. After 45 minutes of hard exercise, people burned 190 kcal more over the next 14 hours, and regular lifting raised resting metabolism by about 96 kcal a day. It is a small bonus, though, far less than what the workout itself burns.

Does exercise raise your metabolism so you burn more even at rest?
'Exercise → faster metabolism → calories burn while you rest' — is that right?
A common belief is that exercise revs up your engine so you keep burning calories while resting, the so-called afterburn. We checked step by step whether you really burn more, how much, and whether it adds up over a whole day.
Do you keep burning more after a workout?
Yes, 190 kcal over 14 hours after hard exercise
10 people stayed in a measuring room all day and cycled hard for 45 minutes. They burned 519 kcal during the ride and 190 kcal more than on a rest day over the next 14 hours. That added 37% on top of the calories burned during exercise.
Does any workout do that?
Intensity set the size of the bonus
An analysis that pooled 22 studies found the extra after-burn was about 69 kcal after intervals versus about 38 kcal after steady moderate exercise. In a trial of 21 people comparing workouts of about 300 kcal, the 30 minutes after intervals burned 66 kcal versus 54 kcal. Light or short workouts left no lasting increase.
Lifting lasted longer
After hard lifting, it stayed high for up to 38 hours
7 people did bench press, power cleans and squats to failure in a 31-minute circuit. Their oxygen use was still higher than at the same time on a normal day 14, 19 and 38 hours later. The daily average was higher on both days after the workout.
Does your everyday resting metabolism rise too?
Lifting raised it, by about 96 kcal a day
An analysis of 18 studies found that cardio did not raise resting metabolism, but strength training raised it by 96 kcal a day. In a trial of 39 people, 6 months of 11-minute lifting sessions 3 times a week raised resting metabolism by 7.4%, measured 72 hours after the last workout.
Flip side: does your body cut back to make up for it?
Exercise calories were simply added on
One analysis of 1,754 people's data estimated the body offsets 28% of extra exercise calories by lowering resting metabolism, but a 2026 review concluded that once misleading correlations are removed, exercise calories are simply added to daily burn.
Bottom line: you do burn more at rest, but it is a bonus
The main event is what the workout burns
You do burn more after exercise: tens to 190 kcal after a hard session, and regular lifting raises resting metabolism by about 96 kcal a day. Still, that is far less than the workout itself. Treat afterburn as a bonus and manage calories through how much you move and eat.
