I have been trying to work out this year but being a science student is hard. I used to be toiling away in the labs a lot, and *if* you had "free" time, it was expected to be used in the lab. Only work out I managed was going up and down the stairs and carrying giant dewars filled with liquid nitrogen. Yes, sad.
Now it's my new year's resolution to get an actual work out going (now that I am no longer working in the lab).
