Just What I Was Looking For!!!

This app is exactly what I needed! I have a workout routine but I really needed a simplified app to keep track of what I get done each day. Plus this app is SO satisfying showing me colors for each group of workouts!! Now I can quickly see at a glance if I’m doing great for the week or need to step up my game!

12 Week Fitness App !!!!!!!!!!

Daily calendar for full body tracking with clearly defined targeting categories. Subcategories are packed with specifically defined exercise types, especially useful for referencing past workouts to plan future routines accordingly. Daily planning and tracking can help you stay focused.

Like the new layout.

Coming from someone who used this in the older versions, it did take me a few minutes to get the new UI figured out, but now it’s smooth sailing. Nice looking back at older workouts, and seeing the color coded main screen.
