Pop star turned professional swimmer Cody Simpson has revealed the intense workout routine behind his champion physique.

The 26-year-old provided all the details in an Instagram post, encouraging followers to stay on top of their fitness routines.

“The destination is the journey, how it shapes you, helps you grow. Build your body and mind while you’re young,” he wrote.

“Choose a path that’ll expand your consciousness and capacity daily. Your future self will thank you.

“Regardless of the outcome, I’m so grateful for what my journey as a swimmer is teaching me – indispensable tools and lessons of perseverance I will utilise throughout my life in the future as a musician, businessman, friend and human being.”

In the clips, Cody is seen lifting weights, doing push ups and weighed pull ups.

Commenters were quick to throw their support behind the extreme efforts, with one labelling Cody a “beast”.

“So much respect earned from the public – you are incredible,” one person wrote.

“Seeing your work ethic really gives me an extra boost to strive for more success in life,” added another.

It comes after the former singer bombed out at the Australian Swimming Championships last week in a result which has left his Olympic dreams uncertain.

He finished eighth in the 100m butterfly final with a time of 53.48 seconds – two seconds slower than national champion Matthew Temple.

From here, Cody’s best chance of gaining an Olympic berth could be in the 100m freestyle event as a relay swimmer.
