Walking for weight loss? YUP!
Contrary to popular belief, you CAN lose weight and get in shape by simply committing to a brisk walk 4-6 days per week.
Aim for a brisk walk of 30 to 90 minutes most days of the week for weight loss. You can walk more on some days and less on others, but the total time for the week should be at least 150 minutes (2.5 hours). – SOURCE
