Push a stream of air from your throat through your open mouth. No tongue or lip contact.

Americans pronounce hundred as HUHN-druhd (/ˈhʌndrəd/). In "hundred", the "dr" cluster blends into a "jr" sound — a natural American English pronunciation. This is called the DR Sounds Like JR, and it's why Americans sound more relaxed than the textbook. It comes out as HUHN·druhd. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "He broke his own personal record in the hundred-meter sprint" or "The bibliography included over one hundred scholarly references" — more examples below.

In "hundred", the "d" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
Stress falls on the first syllable, not the others. Stretch HUHN — keep everything else short and quick.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
