Čitam svoj plan treninga.

Because svoj is the reflexive possessive adjective in Serbian. It means something like one’s own.

In Čitam svoj plan treninga, the subject is I, and the plan belongs to that same subject, so Serbian normally uses svoj:

• Čitam svoj plan treninga. = I’m reading my own training plan.

You can sometimes hear moj, but svoj is the standard and most natural choice when the possessor is the same as the subject of the sentence.

Compare:

• Čitam svoj plan. = I’m reading my own plan.
• Čitam njegov plan. = I’m reading his plan.

So svoj helps show that the plan belongs to the person doing the reading.

The whole object phrase is in the accusative, because it is the direct object of čitam (I read / am reading).

However, the nouns behave a little differently inside the phrase:

• svoj plan = accusative singular
• treninga = genitive singular

Why?

• plan is the main noun, and it is the direct object, so it goes in the accusative.
• treninga depends on plan and means of training / workout, so it goes in the genitive.

In masculine inanimate nouns like plan, the accusative singular is the same as the nominative singular, so plan does not change form.

Because after a noun like plan, Serbian often uses the genitive to express of ....

So:

• plan = plan
• treninga = of training / of workout

Together:

• plan treninga = training plan / workout plan

This is a very common pattern in Serbian:

• čaša vode = a glass of water
• kraj filma = the end of the film
• program kursa = the course program

So treninga is genitive singular of trening.

Because plan is a masculine inanimate noun, and in Serbian those nouns usually have the same form in nominative and accusative singular.

So:

• nominative: plan
• accusative: plan

That is why you see:

• Ovo je plan. = This is a plan.
• Čitam plan. = I’m reading a plan.

If it were a masculine animate noun, the accusative would usually look like the genitive instead.

In Serbian, the present tense can often cover both meanings, depending on context.

So Čitam svoj plan treninga can mean:

• I am reading my training plan.
  or
• I read my training plan.

In many everyday situations, without extra context, people will understand it as I’m reading my training plan.

If you want to make the ongoing action extra clear, context usually does that naturally. Serbian does not need a separate grammatical form like English am reading.

The infinitive is čitati = to read.

Čitam is the 1st person singular present tense form:

• ja čitam = I read / I am reading

A useful mini-conjugation:

• ja čitam = I read
• ti čitaš = you read
• on/ona/ono čita = he/she/it reads
• mi čitamo = we read
• vi čitate = you read
• oni/one/ona čitaju = they read

So in the sentence, čitam already includes the meaning I, which is why Serbian often leaves out the pronoun ja.

Yes, absolutely.

• Čitam svoj plan treninga.
• Ja čitam svoj plan treninga.

Both are correct.

Serbian often drops subject pronouns because the verb ending already shows who is doing the action. So čitam already tells us the subject is I.

Adding ja usually gives extra emphasis or contrast, for example:

• Ja čitam svoj plan treninga, a on gleda televiziju.
  = I’m reading my training plan, and he is watching TV.

So without emphasis, leaving out ja is very natural.

It is a very natural and common way, but not the only possible wording.

Plan treninga literally means plan of training, and this is a standard Serbian structure.

Depending on context, you might also see phrases like:

• plan za trening = plan for training
• program treninga = training program
• raspored treninga = training schedule

But for training plan / workout plan, plan treninga is perfectly normal and idiomatic.

A rough pronunciation guide for an English speaker is:

• Čitam ≈ CHEE-tam
• svoj ≈ svoy
• plan ≈ plahn
• treninga ≈ treh-NEEN-ga

A few key points:

• Č is like ch in church
• j is pronounced like English y in yes
• Serbian spelling is quite phonetic, so words are usually pronounced close to how they are written

So the whole sentence is approximately:

CHEE-tam svoy plahn treh-NEEN-ga

Yes. Serbian word order is more flexible than English word order, because case endings help show the grammatical roles.

The neutral, natural order here is:

• Čitam svoj plan treninga.

But other orders are possible for emphasis, such as:

• Svoj plan treninga čitam.
• Plan treninga čitam.

These alternatives can sound more marked, poetic, or contrastive depending on context. For a learner, the basic order verb + object in this sentence is the safest and most natural choice.

Čitati is imperfective. That means it describes an ongoing, repeated, or general action rather than a completed one.

So Čitam svoj plan treninga presents the action as:

• in progress,
• habitual, or
• simply viewed from the inside, not as a finished whole.

The perfective partner is usually pročitati = to read through / to finish reading.

Compare:

• Čitam svoj plan treninga. = I’m reading / I read my training plan.
• Pročitaću svoj plan treninga. = I will read through / finish reading my training plan.

So yes, aspect matters, and čitati is the normal choice if you just want to say you are reading it.
