The elliptical is a nice alternative and I am a fan but I also view it as a form of work. While the idea of it is great, it's just a machine built for repetition. Nothing stimulating about that. The end justifies the means but the means are a bit boring, HDTV or not. Some of my running friends are taking to their bikes for the summer and I'm starting to think about doing that as well but my bike needs a serious tune up or replacement. In the meantime my non-running choices are limited.
This morning I decided to give my legs a rest and instead did some work on my much neglected upper body. This, like the treadmill and the elliptical, is a tedious process. I worked with two 10 lb. free weights and did lots of repetitions, isolating different muscles each time. I spent about 25 minutes on this activity and built a good sweat (though nothing like what a get from a run). I have no idea if it did any good but I was happy that I gave my legs a break and still did a workout. All the same I'd rather be running.
