Thomson (57), a former president of Bowls Dunedin, has lost 16kg over the past two years to reduce his weight to 79kg.
He is now bubbling with energy and a weekend's bowls is easy for him. It has also improved his focus and concentration during a game.
It has paid dividends for Thomson, who has won three Bowls Dunedin titles and been runner-up in another event in the past 12 months.
Thomson, who has represented New Zealand in two Professional Bowls Association events in the United Kingdom, won his first national outdoors title with Blair Barringer and Peter Barron in the champion of champions triples last season.
Thomson's latest success came last weekend when he won the Bowls Dunedin mixed pairs with Janet Swallow (Taieri).
They beat last year's champions Jacqui Peterson (Andersons Bay) and Dwayne White (Forbury Park) 18-8 in the final.
They were leading 10-6 after nine ends when they collected a five on the 10th end to lead 15-6. Thomson drew two bonus shots to ram home the advantage. It was the 14th Bowls Dunedin title for Thomson and the 11th for Swallow.
Thomson started playing bowls in Alexandra in 1985 and won his first Bowls Dunedin title in the open fours in 1991. He gained a bar to his gold star when he won his 10th title in the champion of champions triples in 2008.
He joined the Body Synergy Gym and came under the influence of masseur Rowan Ellis when he had a painful lower back making it difficult for him to play bowls.
''Rowan structured me up and fixed my back,'' Thomson said.
''I go to the gym five days a week.''
Ellis has assisted bowlers to get back on the green for several years with the most notable occasion being at the New Zealand championships in Dunedin in 1992.
Mike Martinovich, the lead in the Auckland Composite four skipped by Nick Grgicevich, had a painful lower back on the eve of the final and was resigned to pulling out of the team.
Ellis fixed his back and he was pain-free when he played an important role in his team's national championship win the next day.
Swallow won her 10th Bowls Dunedin title in the open pairs with fellow Taieri bowler Wendy Hurring two years ago.
Her crowning achievement came in 1998 when she was lead in Mata McEwan's Dunedin composite four that won the national title in Palmerston North.
She was selected in the New Zealand development squad at that time.
The Southern connection of the Kitty Hawks was formed 18 years ago by the late Stan Seear to raise money for charity.
The Kitty Hawks Foundation is based in Auckland and raises money for the Halberg Trust through bowls tournaments each year.
Seear, a former New Zealand selector, brought region six into the fold and it holds two tournaments each year to raise money for charity and promote bowls.
It holds a regional mixed under-20 tournament each year and sends seven bowlers to the New Zealand finals.
On November 3, the Kitty Hawks will hold its annual charity fours tournament and expects to raise $5000 for Camp Quality which supports children living with cancer.
''We have raised $95,000 for various charities in the last 18 years,'' local Kitty Hawke patron Ken Walker said.
Fifty teams have entered for the event that will be held at the Taieri (headquarters), Fairfield and Green Island clubs.
