We’ve all heard about the “After Burn” effect of exercise.

That coveted condition where the body continues to burn calories long after we’ve finished working out.

Well, it seems that science may have proven that this does indeed happen and at a higher and more intense rate than expected.

Studies which are done properly (many are not), find that extra calories are burned in the hours after exercise — but only if subjects exercise hard and long; intensely for 45 minutes.

And if they exercise even harder, they burn even more calories afterward.
