Leaving Hale to look after young sons Kaiden and Arlo for seven weeks was heart-wrenching. Yet still, the 8-3 super featherweight knocked on undefeated welterweight Alex Cooper's door to start a seven-week camp he hopes will change his family's lives.

Lantry lived and trained with Cooper - up to three times a day, six days a week - under the watchful eye of former world title challenger Jamie Pittman in Canberra.

All with an eye on a showdown with Paul Fleming [26-0-1] on the undercard of Tszyu-Hogan in Newcastle on Wednesday night.

It was the perfect tonic for a man looking to build on what was dubbed the upset of the year in 2020.

"Axe [Cooper] is a great fighter, he's tough, he's repetitive, he's consistent with what he does. For someone like me who can switch off at times, I never got that chance," Lantry said.

"I'm competitive as hell, so the harder my training partner works, the harder I'm going to work. Axe is the same. To be a full-time athlete, wake up, train, day in day out, three times a day for six days a week, with very little stress behind me because my partner took on so much while I was gone, has just been incredible."

Sundays were Lantry's rest day, yet no matter how fatigued he might have been, he spent it driving home to see his loved ones. He saw it as the least he could do.

"What my partner had to take on was not only my kid pretty much full-time, but also running my boxing gym," Lantry said.

"She had to take on coaching and running the gym after her full-time job from nine to five at work. The stress and the importance both jobs had to be done was massive.

"It's not something I'm going to let go of. I belong on the big stage and I'm going to prove it."

Proving it against undefeated excitement machine Fleming will be no mean feat.

"He's a family man like me, I wish him and his family the best, but it doesn't mean I'm not going to snatch his soul on Wednesday," Fleming said.

"Me and Tyson have been talking for years man, [we] have a good relationship. I even messaged him during camp saying 'hey brother, hope camp is going good, hope you get through camp injury-free, and I hope you come in 120 per cent'.

"On Wednesday, it's all business, it's showtime."
