Workout app with only standing exercises?

I used to have a workout app, that would give you a few exercises to do every day (it's called Six Pack in 30 Days, just to let you know exactly what type of app I'm talking about). I liked the motivation it provided me to complete the daily workout, and that I didn't have to think about which exercises I should do, so I'm looking for something similar. The problem is that I'm currently in a living situation where I can't really lay down on the floor to do the workout, so I'm looking for an app that only has (belly or better yet, full body) exercises that I can do without laying down (preferrably standing up, next to a wall, or maybe sitting in a chair). It would be great if it was open-source, but if it isn't, it should work without Google Play Services and internet connection. Thanks a lot for your help!
