how often do you increase your treadmill workout?

[newholidayx2]

Been walking 3.9 miles per hour on incline 2 for about a month now
Just today started walking at 4.0 - havent raised incline from 2

How often do you increase your speed? incline?
have you found a preprogramed program that you like?

i like to mix it up -- if you do the same over and over your body gets used to it and it's not as effective

do you have personal trainers at your gym that could help you work up a program?

what is your goal? speed? endurance? build up muscle?
