There are three I found that are about ten minutes each. That is a little less than I wanted, but works out great. Depending on the time I have I either do two of them, or all three. I included the videos so you could view them first, and the link if you want to save them.
The last one is the most intense because each exercise lasts a minute. Does not seem like much until you are burning for that minute to end. Modifications are included so for you beginners out there this is a great way to get started.
