You do not have to walk for hours, count calories or steps. A brisk 20-minute daily walk has many health benefits and covers your recommended 20 minutes of exercise a day. If you want to do more gradually increase your pace or distance (not both at the same time though).
A distance of 2 miles should take around 30 minutes. 1 mile will take around 18 minutes, while 0.8 miles will take around 14 minutes.
As a general rule, the faster you go, the more calories you will burn exponentially since your body uses more energy to go faster. At a moderate speed per hour you will burn less calories than walking at a faster rate, e.g. a moderate to fast pace.
Several studies have found shown high-intensity training (HIIT) significantly reduces total abdominal fat, including visceral belly fat more effectively than lower-intensity exercise like walking.
2 miles should take about 34 minutes on average.
