The app for this week is the Spartacus Workout Challenge. This app is similar to the Men's Health featured workout (yes, there is an app for that also). The thing that is great about this app is that you can chose different exercises and also change up your time settings. This is a paid for app that costs $1.99, but there are several free Spartacus Workout apps that you can download to see how the workout system works.
