The LifeFitness line of cardio equipment is what I use daily. Although I do not own the treadmill personally, I do attend the gym where all they use is the LifeFitness line. The machine has improved greatly, it's iPod compatible and has a personal trainer function. The machine does what it is supposed to do, it can push you or you can choose your own manual course. This treadmill is a nice and easy one to use and function with. Made for any user.
