After a whole year off, Santa's obviously got to warm up for that sleigh ride somehow...
In order to successfully deliver presents who all those deserving children (and hard-working journalists) in just one night, you have to figure that Santa ends up pulling more than a few Gs (about 17,500 if you believe the calculations on one website). That's a bit more than the six Gs that Deakin University's Universal Motion Simulator (aka flight simulator on a giant robot arm) maxes out at, but it looks like Santa is more or less satisfied with his pre-flight workout:
