In general, I am stoutly pro-gym and think that people who try to do all this stuff at home are generally delusional. But there are days…. So yesterday I bought a mid-level elliptical machine for the house, for those days when things get crazy and you have to jam in some exercise. And when you’re tempted to skip the whole thing. I know that huge numbers of people do use machines at home. But do they work for you? Do you actually use em or is it just a balm to you guilt? Please comment.
