Will I get stuck behind a desk?

I am a first-year mechanical engineering undergraduate. I love what I am doing now but I was wondering what it will be like when I leave university. What will I actually be doing in the work place? I know that is difficult to answer considering there are so many jobs you can do but my main concern is just being sat behind a desk for my whole career. Is it all desk jobs and paperwork or can you often get out and about and hands on with machinery?
Many thanks!
