Great ab workout

This is a great free ab work out. Its not overloaded with pop-up ads and it does the job. Also, after you are done with one challenge you can start another. I like how it helps you keep track and sends reminders for accountability. I think It would be nice to have a option to have friends. Instead of sending progress pictures, have a way to communicate through the app. But for what its worth, its great.
