LARRY Emdur has joined&nbsp;locals in a boot camp fitness session at Toronto High School this morning. The TV personality was among 80 men and women who took part in the work-out, led by personal trainer Cameron Byrnes. The boot camp was the fourth in a series, and the culmination of a 12-week healthy lifestyle program presented by Toronto Diggers called 'If Not Now, When, Toronto?'. Emdur told The Lakes Mail the Toronto program was modelled on the healthy lifestyle regime that helped him to win the&nbsp;Men's Health Magazine&nbsp;health challenge last year. "The program I was on was run by Cameron who is absolutely the transformation king," Emdur said. "It changed my life.'' Emdur said the approach last year of his 50th birthday proved to be a catalyst. ''I was&nbsp;13 kilograms overweight, and feeling pretty miserable," he said. "I was 49 and realised that I had to make some changes.'' Emdur said he was now&nbsp;surfing and running with his children, and feeling energised. He said he enjoyed seeing local participants transform their lives through the healthy eating and exercise program. "The results have been amazing, and we've seen a combined weight loss of something like 500 or 600 kilograms,'' he said. He praised Toronto Diggers for sponsoring the program and bringing it to the local community, describing the club as a "caring entity". Toronto Diggers secretary manager Cathy Handcock said feedback from the program participants had been very positive. ''One member from our club is 49 and said she was using all of the excuses for not exercising. She said it was too late to start worrying about fitness at her age, and that she couldn't get off the lounge. "But you should see her now. This has changed her life." Participants ranged in age from 18 to 85. ''The average weight loss was 5 kilograms," Ms Handcock said. Ms Handcock said the 12-weeks had kick-started a new way of life for her. "I had stopped exercising, but I've joined the gym again now, and I'll continue to exercise," she said. "I'm not so tired, and have a lot more energy for my grandkids who aren't so heavy now."
