Every week about 40 to 60 seniors attend Fifties Forward, a weekly fitness class held at Gisborne's YMCA.
Over the years up to 90 people have attended one class.
For the 30th anniversary of Fifties Forward due in September, club chairwoman Joanne Keong said they will have a pearl-themed luncheon to celebrate.
Originally a referral-based class via Sport Tairāwhiti, it has evolved into a social club that includes exercise.
Before Covid-19 hit the Fifties Forward committee organised trips out of town for shopping, concerts and sightseeing.
