Petra - Personal trainer

This app will coach you through good workouts!

Simply start a workout, turn up the volume and Petra will tell you what exercise to do and for how long via the speakers.

Petra has a built in timer and comes with a few pre-programmed workouts, including the popular "7 Minute Workout".
A great feature is that she will also tell you when half of the time has past, allowing you to switch from one side to another if you need.

You can also create your own workouts with your own exercises, simply give your workout a name and write a comma separated list of exercises and your good to go!

Petra has three types of workouts: "double workout", "single workout" and "stretching".

The double workout is the longest and most intense program:
1 First exercise for 45 seconds
2 Second exercise for 45 seconds
3 The first exercise again for 30 seconds
4 The second exercise again for 30 seconds
5 Then a pause for 15 seconds
Then the next set starts with the third and fourth exercises...

The single workout is slightly shorter:
1 First exercise for 30 seconds
2 Pause for 10 seconds
Then the next exercise...

The stretching program is the fastest.
1 First stretching exercise for little over 20 seconds
Then the next stretch exercise without any pause.

So: download this app and let Petra take control over your fitness!
