There needs to be a change to the dynamic of any training in the areas of total fitness from a classroom environment to a gym or field environment to initially bring people together for something they’ll care about. So for starters, put together regular PT sessions for your team/section/unit. This doesn’t have to be a huge endeavor and only needs to include an amount of people you can regularly sustain influencing to work out routinely.

What is keeping my unit from achieving total fitness? What are the best strategies for implementing it? Why can't I just continue on with business as usual with tried and true annual training classes?

“'Fitness' is a commonly used word in our society today but within the military it has a particularly deep meaning. Conventionally, being fit means being adapted to a particular condition or circumstance. In war, militaries and their individual combatants must adapt to the chaos and complexities of battle. As these militaries return from war, they must maintain a state of vigilance while also peacefully coexisting within the civil society that produced them. " (Admiral McMullen, USN (Ret))
