I made a basic HIIT timer so I wouldn't have to rely on online pages and really terrible HIIT phone apps that do too much for me anyway. It's the bare minimum:

• Say (with TTS) and display the current state of the routine (exercise name, rest, upcoming exercise)
• Make your routine on the fly
• Load up created plaintext routines

It doesn't do anything else and there is no reason I can find for it to do anything more.

Preset routines can be loaded into HIITimer with the -f flag followed by the filename:

python3 hiitimer.py -f preset1.hiit

There are four fields necessary for a successful routine file:

• exercises: - A list of exercises which will comprise one rep. This list is comprised of an exercises: line, followed by an exercise on each subsequent line.
• exercise_time: - How long to spend on one exercise in seconds. This and all the following fields are to be comprised of the key and value on the same line.
• rest_time: - How long to spend resting between exercises in seconds.
• reps: - How many cycles of the list of exercises to do in total.

The parser overlooks blank lines and lines that begin with #.

A sample routine looks like this:

# Sample Exercise Routine 1

exercises:
	Pushups
	Squats
	Plank
	Jumping Jacks

exercise_time: 30

rest_time: 10

reps: 4

This program and all the TTS has only been tested on OSX, so please let me know if you get any errors, as I'd love to figure it out :)
