How can I actively keep a straight face when my boss tells us to relieve job stress by doing "deskercises"?

deskercises? wow, we actually had a meeting once where they showed us (and made us practice) these so-called deskercises. I felt ridiculous but in the end your boss is just trying to take care of his employees and make sure they don't end up with fatigue or muscle tension (issues with arms, wrists, etc) because that leads to time away from the office. It is nice they are thinking of you so although you might not do finger warm-ups you might want to take small breaks and walk around or do something active so your body doesn't get strained from sitting in the same position all day. We had individual ergonomic essments at our office and I even got laminated instructions of exercises. Do I do them? ha! no! but I get my hands away from the computer every now and then because i do have problems with my wrists.
