Trainer Droid is an application designed to help you get into shape. The concept is simple, create a workout and fill in the exercises you will perform in your workout and the number of repitions for each set of the exercise. Then begin your workout and the personal trainer will tell you which exercise to do and how many reps to perform. When you have completed the set, click proceed and the personal trainer will let you rest for the amount of time you entered for the rest time. At the end of the rest time, the personal trainer will tell you to perform your next exercise.
