The two-piece ensemble showed off her torn abs and toned arms.

Amy complemented her ensemble with a glittery Prada handbag and Cinderella themed heels.

She wore her chocolate tresses back in a tight bun and looked flawless in copper-toned makeup.

Both Jono and Amy have moved on after ending their marriage earlier this year.

Amy is now dating pro soccer star Aaron Evans while Jono is enjoying a romance with model Simone Holtznagel.

The owners of the popular gym Acero split in January. A source close to the couple told Chron Australia they split early last year and then kept up the gig for several months.

Although they are no longer together, they remain good friends and continue to run their fitness empire together.

The couple first met on MySpace 13 years ago before later meeting at a nightclub and falling in love.

Jono proposed in Maui, Hawaii on Amy’s birthday, and she described the proposal as romantic and luxurious.

She told Husskie magazine: “The concierge took me to the beach, the sun was going down and I walked down those stairs and there was Jono surrounded by candles and rose petals everywhere!

“He worked with the Executive Chef at the Four Seasons Maui and put together a menu of all my favorite dishes for the evening. It was absolutely magical.

‘I was so surprised! Jono and I discuss everything, but he designed my ring and organized it all without me knowing.”
