انا بتعلم في الجيم اعمل التمرين صح عشان ضهري يبقى مرتاح.

Because انا is often optional in Egyptian Arabic.

The verb بتعلم already tells you the subject is I here, so the sentence could simply start with بتعلم. Adding انا can:

• make the sentence clearer
• add a little emphasis
• sound natural in casual speech

So both are possible:

• انا بتعلم...
• بتعلم...

بتعلم means I learn or I’m learning, depending on context.

It comes from the verb اتعلم = to learn. In Egyptian Arabic, the prefix بـ often marks the present/habitual form.

So:

• بتعلم = I learn / I’m learning

In this sentence, the meaning is clearly ongoing, so it is understood as I’m learning.

A common pronunciation is batʿallim.

Because في literally means in, but with places it is often translated naturally as at in English.

So:

• في البيت = at home / in the house
• في الشغل = at work
• في الجيم = at the gym

This is a very normal use of في.

Yes. الجيم is a borrowed word from English gym.

Egyptian Arabic uses many everyday loanwords, especially for modern places and objects. The word takes normal Arabic grammar, including the definite article الـ.

So:

• جيم = a gym
• الجيم = the gym

Here it means I do / to do, not a command.

In informal Arabic writing, the hamza is often left out, so اعمل may stand for أعمل. In more careful spelling, you might see:

• أعمل = I do

Without vowel marks, اعمل can look like the imperative Do!, but the context makes the meaning clear here:

• بتعلم أعمل... = I’m learning to do...

So in this sentence, it is definitely not a command.

Because Arabic does not use an English-style infinitive marker like to.

In Egyptian Arabic, after a verb like بتعلم, another verb can often follow directly:

• بتعلم أعمل = I’m learning to do

If you want to make the idea of how to do more explicit, many speakers would say:

• بتعلم إزاي أعمل التمرين صح

So the original sentence is using a very normal Arabic structure, not leaving anything out by mistake.

التمرين is singular, so it usually means the exercise or that exercise.

At the gym, this often refers to one specific movement or drill, not exercise in general. So:

• التمرين = the exercise / the movement
• التمارين = the exercises

As for صح, it literally means right / correct, but here it works like an adverb:

• اعمل التمرين صح = do the exercise correctly

This is very common in Egyptian Arabic. Instead of changing the adjective form, everyday speech often just uses صح in an adverb-like way.

It can mean both, depending on context.

Common meanings of عشان include:

• because
• for
• so that / in order that

In this sentence, it means so that:

• عشان ضهري يبقى مرتاح = so that my back will be comfortable

So here it introduces a purpose, not a reason that comes afterward.

ضهري is:

• ضهر = back
• ـي = my

So:

• ضهري = my back

About the spelling: in more formal Arabic, you may see ظهري from ظهر. In Egyptian writing, especially informal writing, people often spell it in a way that reflects everyday pronunciation, so ضهر is very common.

The important thing for a learner is:

• ـي attached to a noun means my
• ضهري = my back

يبقى مرتاح here means something like be / stay comfortable.

In Egyptian Arabic, يبقى is a very common everyday verb that can mean:

• remain
• become
• be, in many conversational contexts

So:

• ضهري يبقى مرتاح = my back is/stays comfortable

This is very natural in Egyptian speech.

A learner might expect يكون because that is the more formal or MSA-like verb for to be, but in Egyptian Arabic يبقى is extremely common.

Also, يبقى مرتاح is a bit different from يرتاح:

• يبقى مرتاح focuses on the state: be comfortable
• يرتاح focuses more on the action/result: get relief / rest

Because ضهر is grammatically masculine, so the adjective has to agree with it.

So:

• ضهر = masculine
• مرتاح = masculine singular adjective

If the noun were feminine, you would use مرتاحة instead.

Here:

• ضهري يبقى مرتاح = my back stays comfortable

The adjective is matching ضهري, not the speaker.
