This song will invigorate you! Make sure to clear some space and don't hit the desk-lamp :-) It's amazing how much one can move in a small space and how good it feels to let loose for a couple of minutes. 3:39 minutes to be exact, is all it takes to relax your brain. It's a great stress reducer!
I did it, yay! . . . it was a great work-out, it woke me up!
