Fremantle senior coach Justin Longmuir is confident his players can maintain the fitness they built up through the pre-season as they commence their training in isolation.

Speaking on Seven News on Wednesday night, Longmuir said he had been in regular contact with the group and ran through the challenges they will face over the coming months.

“I’m keeping in touch over the phone just to make sure that they’re doing their programs,” Longmuir told Seven News.

“It’s just really checking in to make sure that they haven’t got any concerns.

“Our players have been training in pairs, and that’s mainly due to the kicking component of their program.

“They’ve got their off-season programs but they’re only allowed to do it in their pairs and gyms have been shut down, so the other difficult part of the program is being able to find gym equipment.

“Our strength and conditioning staff have put in a really good program for them to be able to maintain their fitness and return in good shape when that happens.”

When asked about a proposed State of Origin concept at the end of the year should there not be time for a full season, Longmuir said he was focused on the earliest possible return scenario.

“There’s been a lot of proposals that have been thrown out,” Longmuir said.

“Everything we’re hearing from the AFL is around getting the remaining 144 games played and they’ve been saying, if that takes us to Christmas, so be it.

“At this stage, we’re planning for (the players to return in May).”

As the AFL’s youngest and newest coach, Longmuir said he was staying level headed as he navigated a bizarre debut season as an AFL senior coach.

“I’m just trying to go with the flow and prepare and plan as well as I can for when the players come back,” Longmuir said.

“It has been slightly different but it’s different for everyone. We’re just trying to navigate it together as a footy club and as an industry.

“(My kids are) seeing a lot more of dad and Melissa’s seen a lot more of her husband than she usually sees this time of the year.

“We’re spending a lot of time indoors, obeying government regulations as everyone is at the moment.

“That’s been a good part of this, being able to reconnect with the family and spend some quality time.”
