Lips
Mouth moderately open, lips completely relaxed and neutral. Not spread, not rounded. The laziest lip shape you can make.
The vowel in "cup". A short, relaxed "uh" from the center of the mouth.
Example words: strut, cup, love, sun, money

Mouth moderately open, lips completely relaxed and neutral. Not spread, not rounded. The laziest lip shape you can make.
Tongue sits mid-central and slightly low, completely relaxed. It shouldn't push forward, back, or up. Just let it rest.
Short. A quick, punchy "uh". Unlike the long central vowel in "nurse", this one is over almost as soon as it starts.
Record "love" and "cup". Both vowels should sound identical despite the different spellings. If "love" comes out with a rounded "o" quality, say it again with your lips frozen in neutral.
Spelling is the trap here. "Love", "come", "money", and "does" all use this "uh" sound even though they're spelled with o. Don't round your lips into an "o" or "oo" just because the letter says so. If your lips move forward, you've lost it.
