What daily tasks and housework count as physical activity?

Activities, yes but: These are physical activities, but unfortunately not adequate in most cases. They do help burn more calories than sitting/watching tv, but they are not considered exercises because they lack adequate increase in heart rate/breathing to have cardiovascular benefit. 30-45 min of moderately intensive aerobic exercise 4-5x/wk is recommended. Live well. Consult doc. Good luck.
