MESQUITE (CBSDFW.COM) – It’s another night at the gym for Jason and Earnestine Cole. From one machine to the next, Jason keeps pushing his mother: For the two, working out means fighting to survive.

“Come on mom you can do it! One more,” he says as she lifts some weights.

Earnestine, 59, was morbidly obese.

“I woke up and couldn’t move anything but my eyeballs,” said Earnestine, who lives in Mesquite. “I was like a walking time bomb.”

One morning in 2004, Earnestine said she felt like she was paralyzed for 28 minutes.

She lay in bed and sang Amazing Grace and prayed. Then she got a death sentence.

At 325 pounds, Earnestine not only had high blood pressure and cholesterol, but heart disease too.

“The doctors gave her 6 months to live,” explains Jason, who lives in Lewisville “I don’t know what life would have been like without my mother.”

Jason, 28, didn’t want to find out and that’s when he changed his life to save hers.

“Jason took away my ice cream, my chocolate cake, chocolate candy and my pie,” Earnestine said. “He replaced it with vegetables!”

From eating habits to working out, Jason became his mom’s personal trainer.

In the process, he changed his major at the University of North Texas from International Business to Kinesiology so he could learn more about the body.

“Every day was a struggle for her I see that she could push through it so I know I could push through it as well,” Jason said.

The two work out five days a week for about an hour a day. Earnestine has lost more than 80 pounds and she hopes to shed 50 more.

“He did save my life! He’s a wonderful son,” Earnestine said. “My health problems I had are gone! I did it naturally!”

Jason, who now lives and breathes fitness, has become an award-winning professional bodybuilder.

It’s something he picked up recently, and he just won an international body building competition in Hollywood.

It’s one of many he’s received. This weekend he’s headed to Reno for another competition.

The two also have a radio show from 8:30 a.m. to 9 a.m. Saturday mornings on KHVN radio. They talk to listeners about healthy eating habits and how to overcome obesity.
