Anyway, to up the hill you must raise your weight, whereas if you were not moving you're legs wouldn't do any lifting. You would be able to tell the difference.
well yes you are raising your weight to walk but how far you've moved your weight is just as far as your weight is moved back. IMHO I don't think you'd be able to feel that this is happening.
