A Seven Minute Workout
I know no better combination of high-intensity interval training, good song-writing, and playful spirit than Jonathan Mann's seven minute workout video. It makes me puff and smile every time i use it. Flap your wings, flap, flap, flap your wings!
Video sourced from YouTube here.
By the way, Mann has been writing a song a day since 2009-01-01.
