Version 4.24.0

This is an update we've worked on for over 2 months, but most of it is invisible: we reorganized the code structure of the exercise library to make it easier to manage and pave the way for further improvements.

With that said, there are still some pretty nice changes:

130 NEW EXERCISES, including:
- One-arm chin-up progressions filmed with the strong @shaq_diesel_1994, who went to American Ninja Warrior.
- Many weight variations, to differentiate exercises based on the kind of weight used (dumbbell, barbell, kettlebell...).
- The most-requested single exercise: shoulder band dislocates, often called the "Yuri shoulder band" after @yuri_marmerstein, who popularized it.
- Many other exercises coming from user requests sent through the app.

EXERCISE PARAMETERS
To improve guidance and add clarity, we now only show the options that were officially validated. Many options will automatically switch you to the relevant exercise variation. If there is an option you need that is not officially available, you can create a custom variation thanks to the new extended custom exercises.

EXTENDED CUSTOM EXERCISES
Your custom exercises now have all the parameters of official exercises available: muscles worked, equipment used, skill tree neighbours, objectives, and more. We've also made changes throughout the app so custom exercises are handled the same way as official ones, making them "first-class citizens".

Many other small improvements and bug fixes come along as well. I hope you enjoy it, and please let us know if you have any questions. Happy training!
