Bodybuilder Josh Sinclair appreciates the body as biology and art form

Josh Sinclair has a love for science and biology. 

So much so that he’s using his own body to further his studies in these areas.

“I like to learn the theory side of things and then put it to the test,” Josh, 25, said.

“A lot of people have the physical ability [for bodybuilding], but don’t understand the theory behind it. A lot are academics, but don’t know how to put it to the test.

“I like to do both.”

Josh, of Cameron Park, appreciates the human body from a scientific and artistic perspective.

“I have a great love for the human body and biology,” he said.

“Your body is basically a biological machine and your brain is basically a biological supercomputer.

“The body is also an art form. There’s something about all of that together that fascinates me.”

Josh, who studies exercise and sports science at the University of Newcastle, is a competitive person.

He’s always been into sport. In this sense, competing in professional bodybuilding contests is a natural progression.

He’s doing well, too.

He recently won a national title in Brisbane and a Mr Universe title in New Zealand in the men’s physique division, which is for athletic body shapes.

In this division, contestants wear boardshorts because their body type is considered to be a beach-style look. Hence, the quirky label of “bodybuilders in boardshorts”.

“The division is for people who have more of an athletic lean look and that’s always been me,” he said.

“I’ll never be a big powerlifter like Arnold Schwarzenegger.”

Josh competes in natural bodybuilding competitions, which means no performance-enhancing drugs are allowed.

“We’re drug-tested at events,” he said.

Josh wanted to build his body without turning to drugs.

“I want to see how far I can take the human body in its natural form,” he said.

Being a competitive bodybuilder was “extremely hard”, especially while trying to maintain a work-life balance.

“If you do it, you’ll definitely find out what you’re made of,” he said.

“It tests you physically and mentally.

“You’ve got to be in the gym between six and seven days a week consistently.”

He follows a strict diet to maintain muscle and keep body fat low.

Calories are heavily restricted. He mostly steers clear of carbs. He avoids alcohol, except at Christmas and New Year.

“The type of food and when and how you have it at certain points in the day has to be controlled,” he said.

“That has to go hand-in-hand with how you train.”

Thankfully, treats are allowed.

“That’s an important part of it,” he said.

“You wouldn’t think having sugars and lollies once a week could help you with weight loss, but it does.”

For six days a week, he eats lots of meats and green beans.

At the end of the week he has a cheat day, but it’s not only for pleasure.

“If you tried to eat greens, meats, low carbohydrate sources and healthy fats for too long, your body is eventually going to die.”

Having a cheat day helps reset his “hormone profile” and provide a psychological break.

He said the hormone leptin enables “your brain to feel like it’s being fed”.

“That correlates with how much body fat you have. When your body fat levels get low, your leptin levels drop.

“If they get too low, this can mess with your hormone profile and some nasty things can happen to you.”

Having a day to eat a lot of healthy carbohydrates and sugars helps avoid this.

So what’s his favourite breakout meal?

“Yogurtland and a kebab,” he said.

Who could argue with that?
