Hall was hampered by a groin niggle and a fractured rib during the pre-season, so to help accelerate his recovery, the Suns went to extreme lengths.
Along with fellow injured duo Seb Tape (knee) and Trent McKenzie (knee), Hall trained as normal at sea level but slept in the club's altitude room throughout much of February.
The results were staggering.
Hall was aerobically tested before the stint, then returned 16 days later with a 7.5 per cent spike in his performance.
The 'train low, sleep high' theory is one that's slowly gaining worldwide momentum.
Hall played the final three NAB Cup matches and said the difference was noticeable.
"I feel a lot fitter, and I'm able to cover the ground a lot more while I'm out there," Hall said.
"We'd spend at least 13 hours a day in the room. Schwerdty (physical performance coordinator Stephen Schwerdt) and the fitness staff decked it all out with beds and tvs, and we had fridge and toaster and everything in there.
"It was better than going back to Arizona and I improved the same as I did there."
Hall played eight games last year, kicking eight goals.
He was outstanding in the last three pre-season matches and capped it with an 18-disposal, three-goal performance against Melbourne at Southport on March 16.
"I'm feeling a lot fitter on the ground and can get to more stoppages and get to more contests," Hall said.
"Half forward is a pretty high work-rate role, getting up and putting pressure on defenders and getting back to the fall of the ball and trying to hit the scoreboard.
"It's a pretty taxing role but it's one I need to mould myself into."
