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

Americans pronounce himself as hihm-SEHLF (/hɪmˈsɛlf/). The L in "himself" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. This is called the Dark L vs Light L, and it's one of the defining features of casual American English. It comes out as hihm·SEHLF. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "He tried to pull himself out of the pool using a pole" or "He fixed the leaky faucet himself to save on repair costs" — more examples below.
