There's also the option of compiling a playlist of awesome music that makes you want to dance that lasts the requisite amount of time (start short and increase it over time as your cardiovascular fitness improves), and then "dancing" to it -- where "dancing" can encompass things that are actual dance moves (sort of), random jumping around and flailing your arms, failed attempts to skip, twirling a broomstick handle over your head as if it was a sword, and anything that keeps you moving for the right amount of time.

(All actual examples I have in fact been doing this morning.)
