PTL will be a good secondary duty sign me up, personally don't think fitness standards are anywhere near high enough and people would do well to embrace the new initiative.
People are worried about lost man hours from going to the gym instead of working! from the many sections i have seen and worked in over the years there is plenty of time to get to the gym! why are all the t bars full of pool wizards and table footie geniuses?
And you don't have to worry about there not being enough space or equipment in the gym, those great big grass things outside your crew rooms called airfields have miles and miles of lovely roads surrounding them that you can use free of charge all year round!
