요즘 means these days / lately / recently.

In this sentence, it gives a sense of an ongoing recent situation, not just this exact moment. So it means something like:

• These days, I’ve been working a lot of overtime...
• Lately, there’s been a lot of overtime...

If the speaker meant strictly right now, Korean would usually use something else depending on context, not 요즘.

야근 means working late, night work, or overtime work, especially staying at work beyond normal hours.

So 야근이 많다 literally means something like:

• There is a lot of overtime
• I’ve been doing a lot of overtime
• I’ve been working late a lot

Even though English often says I work overtime a lot, Korean often phrases it as overtime is 많다.

In 야근이 많아서, 야근이 많다 is the basic pattern.

Here, 많다 means to be many / to be a lot. The thing that is numerous or abundant gets the subject marker 이/가.

So:

• 야근이 많다 = There is a lot of overtime / I have a lot of overtime work

This can feel a little different from English, because English often makes I the subject, but Korean often makes the thing itself the subject.

-아서 / -어서 connects two clauses and often means because, so, or and as a result.

So:

• 야근이 많아서 = because there’s a lot of overtime / since I’ve been working late a lot

In this sentence, it gives the reason for the second part:

• Because I have a lot of overtime, I don’t have time to exercise in the evening.

This is a very common way to express cause in Korean.

Here, 에 marks the time when something happens.

So:

• 저녁에 = in the evening

It tells you the time frame for the action or situation:

• 저녁에 운동할 시간이 없어 = I don’t have time to exercise in the evening

Time words in Korean sometimes appear without 에, but with words like 저녁, using 에 is very natural here.

This is a very common learner question.

운동할 시간 means:

• time to exercise
• time available for exercising

Here, 할 is the modifier form of 하다, and it describes 시간 as time in which one would do exercise.

By contrast, 운동하는 시간 usually means:

• the time spent exercising
• the time when one is exercising

So the difference is roughly:

• 운동할 시간 = time to exercise
• 운동하는 시간 = time spent exercising / exercise time itself

In this sentence, the speaker means they don’t even have the opportunity or available time to do it, so 운동할 시간 is the natural choice.

Because 없다 works with the thing that does not exist or is not present as its subject.

So:

• 시간이 없다 = there is no time / I don’t have time

Even though English says have, Korean often expresses this idea with 있다 / 없다:

• 시간이 있다 = there is time / to have time
• 시간이 없다 = there is no time / to not have time

That is why 시간 takes 이/가, not 을/를.

It’s omitted because it’s understood from context.

Korean very often drops subjects like I, you, or we when they are obvious. In this sentence, the implied meaning is:

• I have a lot of overtime these days, so I don’t have time to exercise in the evening.

A more explicit version could be:

• 저는 요즘 야근이 많아서 저녁에 운동할 시간이 없어요.

But in natural Korean, leaving out 저는 is very common.

없어 is the casual/plain informal form. 없어요 is the polite form.

So the sentence as written sounds like:

• casual speech
• diary style
• talking to a friend
• an informal written example

If you want to make it polite, you can say:

• 요즘 야근이 많아서 저녁에 운동할 시간이 없어요.

The meaning stays the same; only the speech level changes.

Not necessarily.

It means there has been a lot of overtime lately, or the speaker has been working late often. It suggests frequency or quantity is high, but it does not automatically mean every day without exception.

So the nuance is more like:

• I’ve been having a lot of overtime recently
• Lately I’ve often had to work late

Yes, that is very close to the literal structure.

Breaking it down:

• 저녁에 = in the evening
• 운동할 = to exercise / for exercising
• 시간이 = time (subject)
• 없어 = does not exist / there isn’t

So literally it is:

• In the evening, there is no time to exercise.

Natural English would usually be:

• I don’t have time to exercise in the evening.

Both express the same idea.
