During the early morning hours in Tyler, a group of East Texans take a 'peaceful' approach in behind healthy. Carole Kronenberg is 78-years-old and has taken Tai Chi classes since 2000.

"It's been so long," Kronenberg said. "But I don't feel less healthy."

She may be in for fitness and maintaining balance, her instructor Brandon Jones, said she's training to fight heart disease. Her instructor said when students are moving slowly, they're working the muscles a little more. Jones said Tai Chi promotes the cardio benefits.

According to the American Heart Association, more than 60% of heart attack patients don't do cardiac rehab. Dr. Sam Daya, a cardiologist in Tyler, said Tai Chi can be alternative for people who are recovering.

"Being effective in implementing programs of health can improve a person's health has dramatic benefits down the road," Dr. Daya said.

In a 2016 study by the UT Health Science Center at Tyler, Texas is ranked the 33rd worst in the nation for heart disease mortality. If Northeast Texas was a state itself, it would be considered the 49th. Health officials suggested having a clean diet and simply walking for 15 minutes can reduce the chances of developing heart disease.
