I created this as a form of alternative fitness testing for the student who may not be able to perform a test but could certainly study the components of a test and re-create it using Scratch.
I used the audio from a YouTube video and converted it to an MP3 file via http://www.listentoyoutube.com/after.php. Then converted the MP3 to a WAV file with zamzar.com. Made the Sprites myself. Played with timing. Created a counter to calculate the total curl-ups.
