Weightlifting: Miles powerhouse Chloe Kerwick has snagged a silver medal at the nail-biting national titles earlier this month.

Fresh off a busy few days assisting with Back to the Bush, Kerwick made her way to Brisbane to compete at the 2018 Australian Weightlifting Federation Junior/Senior Championships.

"I have never been so nervous in all my life,” an elated Kerwick said.

"Lifting the best that I could was my major goal going into the competition.

"I was so so happy to walk away with a silver.”

Kerwick's year of intense training and competition boiled down to her lifting a personal best of 75kg in the snatch category and 97kg in the clean and jerk.

In what turned out to be a close competition, Kerwick's overall total of 172kg was enough to secure her second place.

The road to glory for Kerwick did not come easy coach Sonia Stenhouse said.

"We got through the snatches and were in a good position,” Stenhouse said.

"But, in the clean and jerk, she got a really bad attack of the nerves.

"She almost gave me a heart attack but it's just something that happens.

"You never know how nerves are going to affect you until you step out there on that platform.”

After two failed attempts in the clean and jerk, the pressure was on for Kerwick's third and final lift.

Pushing nerves to the side, she was able to lift 97kg.

"There was a lot of pressure on Chloe and she did astoundingly well to rise to the occasion it was so high,” a proud Stenhouse said.

"She showed a real gutsy spirit.”

Kerwick contributed to the landmark overall success of Queensland teams who procured a clean sweep of the four shields up for grabs.

Competitors took out wins for the Best Junior Female Team, Best Junior Male Team, Best Senior Female Team and Best Senior Male Team.

With nationals behind her, Kerwick has her sights set on getting stronger and qualifying for bigger competitions abroad.

Reflecting on her medal success, Kerwick wished to extend a "massive thank you” to her coach.

"Sonia really does everything for me,” she said.

"I am so appreciative of all the time and effort she puts in for me.”
