How often should you walk? Should you focus on miles or minutes? This was a question that I always waned to know since walking is really the best form of getting in shape. Number of Days Per Week, Aim for a minimum of 3 days a week, and gradually work your way up to 5 or 6 days a week. The more the better--especially when it comes to weight loss. But don't forget the importance of rest and recovery--give yourself at least 1-2 days off each week.
