It's a Wednesday during the AFL off-season and Harry Sheezel is stepping into the cryotheraphy chamber.

"It's technically minus 100 degrees in there, but it doesn't feel like that," Sheezel says. 

Tapping into the same science that's behind ice baths, Sheezel uses cryotherapy to prepare him to train at his best. The short, sharp sessions help ease inflammation, he says, and keep him alert.

On the field, the two-time Syd Barker Medalist is ice cool, crafty and always one step ahead of the opposition.

In the third and final episode of NMFC Media's 'Make It Happen' documentary series, Sheezel takes viewers into his world away from the footy field.

The ultimate professional, Sheezel explains how he strives to get the very best out of himself - and what drives him.

"Everything I do is not just for me to be good footballer," Sheezel says. 

"It's for us to succeed. That's what I'm going to continue to do and hopefully help others do as well. That's where we want to get to."

On top of the effort he puts in at Arden Street, Sheezel's average week includes cryotherapy, low central nervous system gym sessions, saunas and extra mobility work.

Leaving no stone unturned in the chase for success, the No.3 says his approach reflects how he's always operated.

"The main thing that I get out of it is the mental edge, and the understanding that I'm doing as much as I can, both physically and mentally," he said.

"That's just the way I'm wired.

"I always try and put 100 per cent into something that I really care about and football's obviously something that I'm passionate about and I want to succeed at."

It was Sheezel's professionalism as a fresh draftee back in 2022 that most struck the club's new captain Nick Larkey.

"He was more professional and just different to any other of the first-year players I've ever seen," Larkey says in 'Make it Happen'.

 "The preparation, who he is … it stacks up."

Sheezel naturally leads by example, Larkey says, which makes him an ideal fit for vice-captain. 

"Everyone knows how driven he is … you think he's this real harsh standard-setter, but it's more how he carries himself. He's just a lovely person, great company to be around, funny kid and great fun to train with.

"He loves the process and thoroughly enjoys the game of football.

"He influences through his action … rather than (being) demanding of everyone."

In his three seasons at Arden St, Sheezel has become "so passionate about the club," he says.

"It's a special place where you feel wanted, you feel included, you feel like you're set up to be the best you can be."

As he and Larkey prepare to lead the Kangaroos into a new era in 2026, Sheezel says he's confident in the current group's potential.

"We have an amazing culture off-field. The boys get along so well with each other," he says.

"I think we laid a really good foundation by having those close relationships, because that allows you to then have that trust on-field, and really challenge blokes and know that it's coming from a good place.

"I think you've seen the maturity of the group over the last 12 to 24 months. We haven't got the reward on-field yet, but ... we have been putting in so much work and laying really good foundations without actually getting the reward just yet.

"I've enjoyed the process and I'm definitely grateful for it.

"It's been very challenging (but) I think it's just going to make the good times even better and more rewarding.

"I have a lot of belief in the group that we have now that it will turn around very soon."

In the third and final episode of 'Make It Happen', Sheezel also talks about his relationship with his family, his coach Alastair Clarkson, North Melbourne's leadership group and more.
