Are Ellipticals any good?

In short my answer to that question would be, definitely, yes, the elliptical is awesome!

The elliptical is that machine in the gym that looks like a step machine but also has two moving arm parts. It's an amazing exerise machine if done right and provides high quality low-impact cardio.

I used the Elliptical first when I had a bad knee and I needed some low impact exercise but since then I use it regular and it's helped vary my routine and now I would consider getting one at home.
