Seems the 7 minutes was taken pretty literally in this app. The article suggests doing each exercise for 30 seconds, followed by 10 seconds of rest, for a total of 7:50. I was confused by each exercise started at :26 and rest at :8.

Would definitely be interested in downloading and tweaking this for my own. Github, perhaps?

Edit: FYI, don't release production code with console.log() if you can help it. :-p
