Walking for Health. The minimum daily requirement for walking is 30-60 minutes a day. If you could package that as a pill, it would be hailed as a medical miracle, as it reduces your risks of type 2 diabetes, heart disease, stroke, cancer, hypertension, and other major diseases.
How much cardio you do should be based on what your health and fitness goals are and what you are physically capable of doing. If you are trying to make a healthy lifestyle change then consider 30 minutes of moderate cardio (walking, hiking, biking) 5-7 days per week.
