I agree with this. Exercise should definitely be enjoyable. The best thing about it is that there are so many activities you can do. Try different things! My personal routine consists mostly of using the elliptical (for me, its more of like a meditative me-time, burns off some stress along with the calories) and a little bit of lifting (I don't really enjoy lifting much, but I do enjoy the feeling it gives me, so I throw it in at least once a week). I've also been doing some bike riding and swimming this spring/summer. I find those activities enjoyable in that it challenges me.
