ATLANTA -- A Cobb County woman is suing her former personal trainer after she says his workout sessions landed her in the hospital.

Susan Guthrie says she had to be put on life support and dialysis after the workouts.

Susan Guthrie’s attorney has filed a lawsuit in the state court of Cobb County and he tells Channel 2 a trial is imminent.

She was 42-years-old when she decided it was time to live a healthier lifestyle and lose some weight. When she went to the gym with her personal trainer, never did she expect to end up in the hospital for nearly 2 weeks.

“For any woman who birthed a child, it was like that but constant,” explained Guthrie.

Guthrie described what it was like after she worked out with personal trainer Ray Crouser 2 times.

“He didn’t listen to what I asked him to do,” said Guthrie.

In her lawsuit, she claims that during the sessions he led her in a regimen of exercises that were too rigorous despite her complaints of pain – starting with the stair stepper.

“It was like I was running stairs from ground zero to the top of the Empire State Building. It was killing my legs,” Guthrie said.

After session number 2, Susan – in excruciating pain – went to her doctor who immediately admitted her to the hospital.

“My thigh tissue had been broken down so severely that it went in and clogged my kidneys,” said Guthrie.

Susan was diagnosed with a condition called Rhabdomyolysis – the breakdown of muscle fibers in the blood. She was placed on life support and underwent dialysis for more than a week.

“In the course of the lawsuit, Mr. Crouser said that he has the same workout routine that he uses for everyone,” said Guthrie’s attorney, Mark Bullman.

The lawsuit contends that’s part of the problem – one size does not fit all.

“If you find a trainer that’s recommended and I say, ‘Have you worked with people over 40?’ It’s a different ball game when you get older,” said personal trainer Phyllis Rogers.

Rogers says she routinely works with those over 40.

“My number 1 rule with clients is, if it hurts – stop,” Rogers said.

Neither the trainer nor his attorney would grant us an interview but the lawsuit states that he, “Contends that Rhabdomyolysis and renal failure were not reasonably foreseeable results of the workouts the plaintiff performed.”

We should mention that there are a number of factors that could cause the condition that Susan had, including a pre-existing medical condition which she says she did not have.

Guthrie filed the lawsuit in 2003, a lot of legal wrangling happened after that, and now she’s prepared to take it to trial.
