Learn Farsi: مربی از اینکه در طول توان‌بخشی به کمرم فشار بیاورم جلوگیری کرد. - The coach prevented me from applying pressure to my back during rehabilitation.

In standard written Farsi, the main verb typically goes at the very end of the sentence. The verb جلوگیری کردن (to prevent) takes the preposition از (from). Here, the structure wraps around the subordinate clause: the subject مربی (coach) starts the sentence, followed by از اینکه (from the fact that) + the entire action being prevented, and ends with جلوگیری کرد. In more casual spoken Farsi, you will often hear the main verb moved up: مربی جلوگیری کرد از اینکه...

If the coach is the one preventing, why is the subjunctive verb بیاورم in the first-person "I" form?

Because there are two different subjects performing two different actions. The coach is doing the preventing, so the main verb جلوگیری کرد is third-person singular. The action being prevented (applying pressure) is something you would be doing. Therefore, the verb inside the اینکه clause must match its own subject: فشار بیاورم (that I apply pressure).

How does the compound verb for "applying pressure" work in this sentence?

The infinitive is فشار آوردن (literally, "to bring pressure"). It always pairs with the preposition به (to), as seen here in به کمرم (to my back). Because it follows از اینکه, it must be in the present subjunctive. The present stem of آوردن (to bring) is آور. When we add the subjunctive بـ prefix, Farsi adds a "y" sound to connect the vowels, making it بیاورم ().
