A rajt előtt bemelegítünk és nyújtunk.

A is the Hungarian definite article, meaning the. So a rajt means the start.

Hungarian uses a before consonant-initial words and az before vowel-initial words. Since rajt starts with r, it takes a.

Rajt usually means start in a sports, race, or competition context. It is the kind of start you would talk about for a run, swim, or other event.

So a rajt előtt is specifically before the start of an event, not just before the beginning in a very general sense.

Because előtt is a postposition. Hungarian often uses postpositions where English uses prepositions.

So:

• English: before the start
• Hungarian: a rajt előtt
• Literally: the start before

This is very normal in Hungarian. Other common postpositions work the same way.

It means before the start.

The phrase is made up of:

• a = the
• rajt = start
• előtt = before

Together they form a time expression telling us when the action happens.

Bemelegítünk means we warm up.

It can be understood as:

• be- = a verbal prefix
• melegít = to warm
• -ünk = we

In sports and exercise contexts, bemelegít means to warm up before physical activity.

So bemelegítünk is we warm up.

Here nyújtunk means we stretch.

The basic verb nyújt can mean stretch or extend. In an exercise context, using it without a stated object is natural, and the meaning is understood as do stretching or stretch ourselves / our muscles.

So no extra word is necessary. Hungarian often leaves such obvious objects unspoken.

Because Hungarian verb endings usually already show the subject.

In both verbs, the ending tells you the subject is we:

• bemelegítünk = we warm up
• nyújtunk = we stretch

You could add mi for we, but it is usually unnecessary unless you want emphasis or contrast:

• Mi bemelegítünk és nyújtunk. = We warm up and stretch.

That sounds more emphatic, like we do it, maybe unlike someone else.

They are both first person plural endings, meaning we, but Hungarian changes vowels according to vowel harmony.

• bemelegítünk has front vowels, so it takes -ünk
• nyújtunk has back vowels, so it takes -unk

So the difference is not a difference in meaning. Both still mean we.

Also, these are indefinite conjugation forms, which fits because there is no definite direct object in the sentence.

Yes. Hungarian word order is flexible, but different orders can shift the emphasis.

A rajt előtt bemelegítünk és nyújtunk puts the time expression first, so it sets the scene as before the start.

You could also say:

Bemelegítünk és nyújtunk a rajt előtt.

That is also grammatical. It may sound a little more neutral, with the actions coming first and the time expression added afterward.

The verbs are formally in the present tense, but Hungarian present tense can also be used for a planned or expected future action, depending on context.

So this sentence can mean either:

• a general habit: Before the start, we warm up and stretch
• a future plan: Before the start, we’ll warm up and stretch

Hungarian often uses the present tense where English might choose will.
