The veterans are participating in the Heart Health Program: a Department of Veteran's Affairs initiative focussing on maintaining the health of former armed forces personnel.

Launceston's Health and Fitness World is facilitating the program for eight servicemen, who are getting help from personal trainer Mark Connelly.

"What the program is looking for is starting at the heart... looking at all the aspects of its impact through nutrition, stress, alcoholism and things like that," he said.

"If we can integrate it into an environment like this where they can actually learn and support each other - that's the key element."

Mr Connelly said it was really important for veterans to engage in healthy behaviours in a social environment.

It's a 12-month program with the end goal of having an education system around living a healthier life post-service.

Group member Lew Jordan joined the program after being diagnosed with atrial fibrillation.

He said he found the program to very fun and relaxing.

"It's very good to meet different people... we're all in the same category which is good," he said.

"When I first was diagnosed with fibrillation I thought it was the end of the world but it's not, you can get yourself to a gym."
