The workout generator is very nice to use when I don’t know what to workout and the create your own workout feature is really nice when you want to program your own workouts or implement a program you’re on. I really enjoy being able to watch my progress over time with the progress tracker. It also has a great user interface and is intuitive to use as well. I would recommend this app to anyone looking for a better way to track progress and stick to a workout schedule.
