"Art- there is, it's a nice old school stair master :) I don't know how to run it, but it can't be too complicated
it gets very little use, but the few times I've seen it in use, looks like a dandy- looks similar to this"
+1 big time. If you can't make it to the mountains, or hills, there is no better machine around to simulate a hill workout, for the simple reason that you lift one foot off the surface with every step, instead of having both feet glued to the pedals of the machine as is the case with all the others(Stairmaster, Elliptical Trainer, etc). Picture yourself on an escalator-same principle. You can vary the step rate from snail pace to throw-you-off-the machine when you're setting up your workout parameters, and modify it on the fly, or go with one of the machine's preprogrammed workouts. You also set the workout duration. Once you get used to the machine and want a different kind of workout, try it with a pack.
