Petra - Unsupported - Personal trainer!

About

This version is no longer supported, use petra.slimsim.heliohost.org/ instead! 

-----

Google will stop support this type of apps. :(

Petra will therefore move to the web instead! From there you will be able to install Petra on your computer and access it offline just like normal.

It will also work perfectly on your smartphone, offline and installable right from the webpage!

What does this mean?

You will still be able to use this app on this computer. But sometime around the summer you will no longer be able to install Petra on new computers. Nor will you get updates to this version. So we highly recommend you to go to the url at the top and get the latest version!

Happy training!

----------------------------

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 core workout and a leg workout. More workouts will be added as time goes by.

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

Get Petra for Android here: https://play.google.com/store/apps/details?id=com.slimsimapps.petra

Now Petra will also tell you the half time, allowing you to switch from one side to another if you need.

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 20 seconds
Then the next stretch exercise without any pause.

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