Q. A 150 lb man wants to design a workout on a treadmill that will expend 300 Kcal. He wants to spend 45 minutes on the treadmill and he wants to walk 3.5 mph. What elevation (or % grade) does he need to set the treadmill at to obtain these results?

Answer

Treadmill run is as simple as running outside but not as same as outside. It is a bit easier than the condition outside. For a man weighing 150 lbs walking for 45 minutes at 3.5 mph to burn 300 Kcal is only possible by the elevation of the belt by 1%.

If the treadmill is not elevated then he might have to increase speed or time to meet the 300 Kcal. In this condition he needs to walk for 2 more minutes. i.e. 47 minutes at the same speed to achieve 300 Kcal target.
