What to bring to a first class
The studio lends mats and cork blocks. The rest fits in a handbag, and almost everyone forgets the same three things.

What you actually need
Something you can squat in without thinking about it, trainers, a water bottle. That is the whole list. Mats and cork blocks live at the studio, so you are not carrying those.
On shoes: any sports trainer is fine to start. If you stay and take up Hyrox you will eventually want a firmer sole for pushing the sled, but that is not a purchase to make before a first class.
The three things people forget
A hair tie
Obvious, and yet. Nobody packs one, and everybody is looking for one ten minutes in.
Something to change into
Especially if you are going somewhere afterwards. A Burn or Hyrox class leaves you soaked, and putting street clothes back on over that is nobody's idea of a good afternoon.
Ten minutes of margin
Not an object, but the most expensive thing to forget. Ten minutes is enough to drop your bag, fill your bottle and tell the coach it is your first time. Arriving exactly on the hour means starting the class already behind yourself.
What to leave at home
Lifting gloves, a belt, or whatever came bundled with a membership somewhere else. None of it is used in a group class, and the studio has what is needed.
If you are still hesitating
The single class exists for exactly this: come once, look at the room, decide afterwards. What is in the studio is on the studio page.
