For a reasonably maintained lawn, this mower is almost effortless to use.  The mower runs on two wheels and two rollers, so pushing it is like pushing a toy cart.  It takes not much effort to push it along foot paths to the destination, and about the same effort on the lawn if your lawn is reasonably flat.  A little momentum will cut the grass effortlessly.  The mower feels a little heavy, otherwise it will not stay on the lawn when you push it.  It's not a problem for a lack-of-exercise person to lift it up and down for a while with one hand.
