Any kind of physical activity will boost your metabolism for several hours after a workout, depending on intensity and duration. So essentially, your body is still burning calories at a faster rate than when you are sedentary. The best way to boost your calorie burn is through strength training which increases your body’s ratio of muscle to fat. Try aiming for 2 sessions a week that work each major muscle group. Use a resistance that doesn’t let you go more than 8-12 reps for each exercise. If you’re a beginner than aim for 10-15 reps.
