Personal trainer

[mikael]

My daughter needs to do some circuit training this summer, to keep up the muscle tone while the regular practices are on hold.

Pythonista provided an excellent tool to create a personal trainer, to guide her through the circuit with voice prompts. See below for the code that uses the scripter to make writing timed actions easier, and to support pausing.

You can edit the amount and order of moves in the list at the beginning of the script. If you try it out, be sure that your Siri language matches that of your voice prompts, otherwise the results may be comical.

Some easy refinements that come to mind:

• Randomize the order of the moves
• Count repeats instead of tracking time
• Show an image of each move
• Play music - although nothing prevents you from playing music in the background, without specific support from this code
