American /t/ at the end of the word

[Over the top]

Hi
Can anyone tell me the tongue position of /t/ sound when it comes as a stop at the end of words?
I tried to raise the tongue as if I am going to say a true /t/ and stop before the tongue touches anywhere, but it sounded too much unpleasent and something different than what native speakers say.
I also tried to raise the tongue as I am going to say a true /t/ and quickly close the vocal folds but it sounds a hard glottal stop.
any ideas?

There's a video at Rachel's English you might find pretty helpful.

Here is a tip about production of /t/ at the end of a word: you should release it like an inaudible release. There is a different between unreleased stops and inaudible releases. This tip works with /p/, /t/, /k/. Many voice trainers teach this.
