Wader 2,
The reality is that we need the deploying troops to be as fit as possible. By increasing specific types of PT we can offset the physical damge that will be sustained when carrying out ops. However, trying to get support from the lords and masters on a frontline unit is nigh on impossible.
If it means that flying units don't fly for a couple of hours each week, then so be it. If nothing else, it creates the bonding that is required when people go to war!
Stop bleating and get down the gym, and take some of your men/women with you.
