Allan Howlings and Maggi Marciniak were joined by more than 20 to perform moves on The Green at Hunstanton.
They ran through routines designed to boost physical and mental well-being including White Ape Gathers Fruit and The Phoenix.
Proceeds from the World Tai Chi Day session will be donated to the RNLI, along with money raised at a sound bath session on 27 April at Old Hunstanton.
'We're passionate about Tai Chi and we're passionate about the RNLI,' said Alan.
'So if we can help them out along the way, it's great.
'I used to be a Royal Life Saving Society teacher, so I know all about the dangers of water.'
The couple have been donating to the charity and other good causes for more than five years, with more than £1,000 raised to help the work of the RNLI.
Pete Griffiths and Jeff Wooldridge, from Hunstanton RNLI's visits and education team, were among those taking part in the session.
Before it got under way, Pete said: 'I'd like to thank you for everything you do for the RNLI and for the well-being and health of the people of Hunstanton.'
Allan admitted to one slight misgiving beforehand.
'I tore a tendon in my shoulder when I was washing the car,' he said. 'I had to go to hospital and have it put back on.
'But nothing else matters when you get into Tai Chi, so it's really good for pain relief - it's better than any pill.'
Notes to Editors
Volunteers at Hunstanton operate both the inshore lifeboat Spirit of West Norfolk and search and rescue hovercraft
Hunstanton Flyer.
They cover The Wash, a tidal estuary stretching for more than 100 square miles fed by five main rivers, along with parts of the north Norfolk coastline.
They are one of the region's busiest crews, who launched 34 times in 2024.
Like those at more than 200 RNLI stations around the coast of the UK and Ireland, their work would not be possible without the kindness of those who donate to the charity that saves lives at sea.

The RNLI charity saves lives at sea. Its volunteers provide a 24-hour search and rescue service around the United Kingdom and Republic of Ireland coasts. The RNLI operates 238 lifeboat stations in the UK and Ireland and more than 240 lifeguard units on beaches around the UK and Channel Islands. The RNLI is independent of Coastguard and government and depends on voluntary donations and legacies to maintain its rescue service. Since the RNLI was founded in 1824, its lifeboat crews and lifeguards have saved over 146,000 lives.
