Whether you are trying to keep a New Year's Resolution or already a gym rat, there are plenty of fitness apps in the Windows Phone Store to help you manage, track and set up your gym routines.
The Windows Phone app has over 130 exercises with guides on how to perform them correctly and the ability to add your own custom exercises. You can create and monitor your exercise routines and receive notifications to help remind you when it's time to hit the gym. WinGym also can be structured for male and female exercises.
In briefly exploring WinGym, it comes across as one of the more basic Windows Phone fitness apps but not too short of features.
