Stop hiding and start training fatties.
Thats just the attitude to get everyone running for fun (an oxymoron shirley).
Like Wm, I too have never failed a fitness test despite now being required to run further now than 9/10 years ago. Holier than thou jockstrap attitudes only strengthen opinions against fitness tests.
A couple of years back when "heat acclimatisation" was brought in the entire shift troggs of to the gym @ 0730 and we are put through our paces by a PTI who was well aware of the vastly differing fitness levels. After about 30 everyone seemed to be enjoying themselves and were giving it a "right go".
Trouble is the flying programm was disrupted and no matter which way we tried to sort it flying came first and we wereprevented from doing our acclimatisation as required.
What I'm getting at is
some people might not voluntarily get to the gym in work time and not be able to do so in their own time. But if you give them the time, then you might just be amazed at how hard people will work at getting fit. After all it is a job requirement not a life one.
Preach less teach more and give people time.
