Low Activity beyond baseline but fewer than 150 minutes a week. Some Low levels of activity are clearly preferable to an inactive lifestyle. Medium 150 minutes to 300 minutes a week Substantial Activity at the high end of this range has additional and more extensive health benefits than activity at the low end. High More than 300 minutes a week Additional Current science does not allow researchers to identify an upper limit of activity above which there are no additional health benefits
