LOS ANGELES, Calif. - Dramatic video shows the moment a car crashed through the window of a gym in California last month.

"I was looking forward to a workout, and I got one," said Samuel Kiwasz.

Kiwasz never expected his regular trip to the gym to become a nightmare.

"It was really scary. I like, saw my life flash before me," he said.

Kiwasz had just arrived at Anytime Fitness when a red Mercedes SUV slammed through the window while he was on the treadmill. Kiwasz was thrown to the ground.

"As I was flying back, I saw the treadmill coming at me, so I twisted it to the side to avoid being crushed," Kiwasz described.

The gym's manager, Nick Vierra, rushed over to help.

"I'm looking to see if there are any more victims. There's nobody there," said Vierra.

He then noticed the female driver get out of the SUV.

"From what I hear, it's pretty normal for people to be out of sorts after an accident like that," he said. "She did have a little bit of a -- of a lack of concern. She didn't look like she was wearing any shoes."

The woman returned to her car and opened the door when an off-duty police officer sprang into action.

"My friend who is a cop, he actually prevented her from entering the vehicle. The vehicle was still running, so it was a little bit of a concern," recalled Vierra.

Incredibly, Kiwasz sustained only minor injuries.

As for the driver, there's been no word on if any charges will be filed against here, but witnesses said she's cooperating with police.
