Fantastic Workout Tracker!!
Admittedly I havent tried any others, but I cant imagine an app being more complete and thorough. There are a ton of exercises for every muscle group.
You can customize your workout or pick youre muscle group and use the exercises it gives you. There is even a section to track your weight loss and calories over time. Theres a section to input your measurements and upload a before and after picture. Theres even a "point" system with levels.
Its overall a really cool app.
