Question: how many calories can i burn walking on a treadmill for 30 minutes?
Answer: Walking briskly on the treadmill for 30 minutes, at a speed of 4.5 mph, a 125-pound person will burn around 150 calories. For a 185-pound person this works out to about 222 calories. While this is an improvement over walking at a leisurely pace, it's still not a major fat burner.
