I made an app called RipDeck based on the deck of cards workout that is great for providing variety to your routine.

We have a weekly featured deck or you can create custom decks. Great for bodyweight exercises. Give it a try. https://itunes.apple.com/us/app/ripdeck/id409921624?mt=8

The featured decks are available on the site if you want some workout ideas for use with a regular deck of cards. http://ripdeckapp.com
