Teresa Reveles, who worked as Simmons' house manager for 35 years, reflected on the fitness personality's death in a July 29 interview with People magazine.

Reveles said Simmons fell two days before his death, and he later told her the morning of his birthday that his legs "hurt a lot." Despite Reveles' recommendation to go to the hospital, she said Simmons chose to wait until the following morning.

Reveles said she found Simmons in his bedroom following his death. Although a cause of death had not been confirmed at the time, she alleged Simmons died of a cardiac episode.

"When I saw him, he looked peaceful," Reveles said, noting Simmons' hands were balled into fists. "That's why I know it was a heart attack. I had a heart attack a few years ago, and my hands did the same."
