Query: Good for days when you can't get to the gym

I am one of those people that hates going to the gym so for days when I can't get myself out of the house, I picked this up. It's better than nothing but be warned that it's really not much of a workout. You can get moving on it and the speed and level of exercise is really up to how fast you move and how much you attenuate muscles while moving but since it's a glider, there is no resistance at all. You won't break a sweat on this, elliptical users: unless you're really hammering out a run, which it's a little too lightweight to feel safe doing, it doesn't get the heart rate up the way a bike or elliptical with resistance does. Still, if you aren't doing anything else, it'll at least get you off the couch and it really does fold up tiny. I live in a minute apartment and it fits behind the TV stand against a wall. Open and in use, it takes up about the space of a double bed, maximum. Not a bad unit but again, not going to make you huff and puff.
