Jeg går til træningscenteret med min nabo, og bagefter sammenligner vi vores kondition uden at konkurrere.

Går is the present tense of gå. That verb can mean both walk and go, and context tells you which English translation fits best.

In this sentence, the important grammar point is that jeg går means I am going / I go in the present. The exact English wording depends on the meaning you were given.

Til means to, so it marks movement toward a destination.

• gå til træningscenteret = go to the gym / fitness center
• være i træningscenteret = be in the gym

So til is used because the speaker is moving toward that place, not just describing being inside it.

Danish makes compound nouns very freely, so træningscenteret is built like this:

• træning = training
• s = linking sound often used in compounds
• center = center
• -et = the definite ending for a neuter singular noun

So:

• et træningscenter = a gym / a fitness center
• træningscenteret = the gym / the fitness center

Unlike English, Danish usually adds the to the end of the noun instead of putting a separate word in front.

After a possessive word like min, mit, mine, or vores, the noun normally stays in its basic, indefinite form.

So you say:

• min nabo = my neighbor
• vores bil = our car

Not:

• min naboen
• vores bilen

This is similar to English: we say my neighbor, not my the neighbor.

Yes. Both are present-tense verb forms.

• jeg går = I go / I am going
• vi sammenligner = we compare / we are comparing

A useful pattern is that many Danish present-tense verbs end in -r:

• sammenligne → sammenligner
• konkurrere → konkurrerer

But gå is irregular, so its present form is går.

Bagefter means afterwards, later, or after that.

In this sentence, it connects the second action to the first:

• first: going to the gym
• then: comparing fitness

You could often translate it naturally as afterward or after that.

This is because Danish main clauses normally follow the verb-second rule.

In the second clause, bagefter is placed first for emphasis. When something other than the subject comes first, the finite verb must come next:

• Bagefter sammenligner vi vores kondition.

Structure:

• bagefter = first position
• sammenligner = verb in second position
• vi = subject after the verb

So og bagefter sammenligner vi is correct Danish word order.

Not usually. In this context, kondition means physical fitness, stamina, or cardio fitness.

So vores kondition means something like:

• our fitness
• our level of fitness
• our stamina

It does not usually mean condition in the broad English sense, like the condition of a car or the condition of a situation.

Vores means our, and it matches the subject vi = we.

So:

• vi = we
• vores = our

This is just the normal possessive form. Danish does have special reflexive possessives like sin/sit/sine, but those are mainly used with third-person subjects, not with vi.

After uden when you mean without doing something, Danish normally uses:

uden at + infinitive

So:

• uden at konkurrere = without competing
• uden at sige noget = without saying anything

Here, konkurrere is the infinitive form, and at is the infinitive marker.

In standard written Danish, yes, this comma is normal because og joins two full main clauses:

1. Jeg går til træningscenteret med min nabo
2. bagefter sammenligner vi vores kondition uden at konkurrere

Since both parts can stand as independent clauses, a comma before og is standard here.
