IT WORKS! 45 minutes of hard exercise increases metabolism for 24 hours

You might want to consider switching your HIIT workout for a longer exercise spell every so often-A new study published in Medicine and Science in Sports and Exercise found that 45 minutes of hard exercise can increase your metabolism by 37 per cent for 24 hours after you clock out

Amazing, right? It’s been known that exercise can increase calorie burn after the fact, but the numbers from this study, conducted at the North Carolina Research Campus by researchers from Appalachian State University and University of North Carolina at Chapel Hill and Charlotte, surprised us.

On exercise day, the guys cycled for 45 minutes at a difficult pace, and their metabolic rate was measured over the course of the day. The rest day was tightly controlled so they would do the same activities, sans workout. The researchers found that the exercise made a major difference in the day-to-day activity calorie burn.

Keep in mind, the study was done on men aged 22 to 33, and women haven’t been tested yet. But we’re pretty sure 45 minutes of hard exercise can only do good things for you.
