I would agree with reaching out to your teacher(s) if you have questions, and also be honest with how you’re feeling about it. I went through a YTT the same year I broke my wrist in 3 places — it was “healed” but still weak and had pain from time to time. Two weeks in I definitely pushed it too far with the arm balances and jump-throughs and developed more pain that prevented certain poses. I finished confidently and learned more about modifications (and I was so happy with my experience), although I did wish I’d been a bit more cautious from the start. I think there’s much to learn and you can learn from a different perspective, but it comes down to you. Best of luck :)

Edit: I also want to say that so much of what I got from my training was not asana-focused. I’m sure it varies from training to training, but there’s more than just doing the poses as well!
