Raise the back of your tongue to touch the soft palate. Add vocal cord vibration, then release.

Americans pronounce gripping as GRIH-puhng (/ˈɡrɪpəŋ/). Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "I couldn't put the book down because the plot was so gripping".
Record yourself saying "gripping" and play it back. The mic stays on your device — nothing's uploaded.

Raise the back of your tongue to touch the soft palate. Add vocal cord vibration, then release.

Curl or bunch your tongue without letting the tip touch the roof of your mouth. Brace the sides of your tongue against your upper back teeth, and round your lips slightly.
Drop your jaw slightly with relaxed lips. Touch the tongue tip behind the bottom front teeth and arch the top-front toward the roof.

The textbook way isn't wrong — it's just not how anyone actually says it.
Stress falls on the first syllable, not the others. Stretch GRIH — 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.
