User Friendly App!

This app is easy to use and straight to the point. The ads do not pop up in the middle of your workout but right after you hit the "Save & Exit" button. It has a new challenge for you everyday with rest days in between. This helps you build the definition you are looking for from beginner to advanced. Once you finish 1 day you can skip along to the next day. I however am following the regimen and cant wait to see my results after the 1st 30 days! Great app!
