One use-case I found somewhat reasonable is to shorten to embed the URL in a smaller QR code, especially ones with lots of parameters.

Love it! Would be cool to be able to optionally select muscle groups first, i.e. before selecting equipment. Also, seeing all available exercises for a muscle group rather than the pre-defined 3 would help tailor the experience more.

Why muscles first?

You generally want to make sure you're working out specific muscles or muscle groups a certain of times each week and with a certain number of working sets, rather than "I have used $MACHINE recently so I need to do that today."

I only have dumbbells, so selecting the equipment first is actually ideal for me

Ah yes that makes sense! I would think of that as more of a pre-workout filter? Where you select the equipment you have available and it automatically filters out everything that requires equipment you don't have access to.

Yeah, that's what the feature is for, not "what equipment do I want to use".

Because the purpose of exercising is usually not to use a certain machine but to train a certain muscle (group).

The feature is definitely not meant to serve as option for what you want to use, but what you can use. You could use it that way, of course, but that's not what it's there for.

Mhh yes that was a question.

Bcs a lot of beginners don’t know what to do with certain equipment, but they do know what they want to train.

That said, I’ll maybe make both paths easier and let users toggle between them!

PR ares welcome

Interesting. I wonder if this is related to how Germans count/pronounce numbers. 21 in your example is "einundzwanzig" in German (or "ein-und-zwanzig", "one-and-twenty")

I think in this case it’s because Hebrew is read right to left, so unrelated.

Yep. The reversed order is also something that you see in archaic English, for example the nursery rhyme, “four and twenty blackbirds”
