This. I remember the first time I got on an elliptical. I went for 5 minutes and then had to get off. My legs were shaking so badly I could barely stand up. I did the same as Windchime - increased my time minute by minute until I could easily do up to 75 minutes, and then I started upping the levels. I love the elliptical now, I've even purchased a cheaper-end one for my own home (though nothing compares to the club models at the gym).

I don't know if it gets easier, but it definitely gets better.

That's a good way to put it. I still have to talk myself into it every night--in fact, I'm reading here now because I'm delaying my workout! But the last week or so, I've noticed something: After my workout, sometimes as much as an hour or two after, I find myself thinking, "I should go get back on that again!" I don't immediately feel an endorphin rush like a lot of people report, but for several hours after I'm done, I'm finding that I feel invigorated or something. I can feel my blood circulating through my body and.....I dunno, I just feel happy that I did it. Especially on days when I wasn't really *feeling* it, but did it anyway.
