To lose 1lb a week, on an average day you should burn around 500 calories more than you eat. To burn this by walking at 3 mph will take about 2 hours and around 60,000 steps every day (just under 6 miles).
For most of this just isn’t practical so look for a balanced routine including some high burn exercises.
