HARD-NOSED Port Adelaide defender Tom Jonas says the Power playing group's focus on improvement in 2015 is reflected in a great on-track attitude. 

The Power is nearing the end of its pre-season training program, with little over a month before the intra-club match that signals the start of the NAB Challenge.

Training has been harder for 2015, with the team sweating it out across two continents with a harder regieme.

Jonas says the Power's original three-year training program, started back in 2012 with the arrival of Ken Hinkley and Darren Burgess, is another step up on what the players have faced in recent seasons.

"We've had a three-year program, so this year's a little bit harder again, but the boys' attitudes have been great," Jonas told FIVEaa.

"We're working really hard and getting as much as we can out of every session and just fine-tuning a few things - game plan and fitness."

The Power's focus on its game plan has included a review of the way the team manages itself during 'crucial' in-game moments. 

And while the club is aware it will be closely scrutinised by the competition for its innovative game plan, Jonas says the key for Port Adelaide is making sure it remains one step ahead of its opposition. 

Execution, therefore, will be crucial in season 2015.

"Whether it's 10 minutes in a final against Hawthorn or a crucial passage of play and being able to execute, under pressure, what we've been training all year ... It [game performance] comes down to those things," Jonas said.

"We relish having teams look at what we do and trying to emulate it, because a few years ago we were in the position of looking at teams like Hawthorn and Sydney.

"It's about getting what we do and improving it once again and just knowing that what we do, regardless of whether the other team knows it or not, we'll be able to do it better."

Plenty of young bodies have continued their development under the Power's fitness program and plenty will push their credentials leading up to the NAB Challenge. 

As with previous years, there's a good chance several new faces will make an appearance in one of the pre-season games against West Coast, Richmond or the Crows, with the NAB Challenge providing coaches an opportunity to review talent and manage the entire list ahead of Round 1.

"I'd say with the boys lining up on the track they get a good opportunity to show what they've learnt and how they're going," Jonas said.

"It's also a little bit of management thing with three or four games before the season starts, just making sure everyone's tip-top for Round 1."
