Battle Prep is the only personal trainer you need. Through muscle confusion, you will unleash your inner Viking warrior self.
Create custom workouts and add exercises to the workouts. Choose which workout routine you want to do and Battle Prep will randomly show you the exercises for that workout. You can choose to either complete the exercise or to skip it and go to the next random exercise. Once you finish your workout, the data for your completed exercises will be saved and can be viewed at any time.
