Electric treadmills are so much in the news that, for what it is worth, here are some of the pros of using them.The advantages of an electric treadmill are that the machine has various programs like a heart rate monitor and calories burned monitor. It is smoother and easier to run or walk on an electric treadmill. A built-in HR monitor gives better control for the intensity of the work out as it ensures that over-exertion does not take place. The incline, too, can be adjusted even while in motion and this definitely gives it an advantage over the manual treadmills.
