Music helps the weary exerciser work harder and, according to a hacker named Steve, the louder the music the more vigorously you work. So, he grabbed a motion sensor and an DIY <a href="http://www.engadget.com/tag/mp3?utm_source=Feed_Classic&amp;utm_medium=feed&amp;utm_campaign=Engadget">MP3 player</a>, stuffed them both into a disused French Vanilla Cafe coffehouse beverage drink container (ooh, la la), then wired the works together to pump out the jams louder when you're really burning those calories -- or to get quieter when you stop for a breather. It's all fearlessly demonstrated in a video after the break featuring Steve, a jump rope, and a little bit of Bono. Make sure you stay through the credits for a deleted scene!
