Is using the elliptical machine the same as running?

It is good to use for speed workouts or/and with ankle weights for improvement on the calf’s but other than that no not really unless your a beginner and are building up the training. They tend to do half the work for you as they make you bounce and spring and the vibrations are going into your legs then back onto the treadmill continuously so you think your are doing very well, where running outside on flat pavement there is no spring to and fourth. It it considerably harder to run on pavement.
