 OJT, or on-the-job training, as an official teaching method used in the United States Navy. So for these command and assistant command fitness leaders, from ships at Fleet Activision Coast Guard, learning the ins and outs of the Navy operational fitness and fueling system, NOS, requires a little sweat. Well, the NOS, I didn't expect it to be as challenging as it is. I thought it was going to be like any other Navy workout, but it's a little challenging. It's a pretty good workout, so I like it. We used to do that interval run, even though it was only 15 minutes, it was actually quite taxing. One of the basic concepts behind the NOS is kind of getting away from traditional way of training your body. I'm trying to mimic the actual moves that sailors perform throughout the day. So I'm taking the movements that I do on the job, and I'm placing those in a training environment. The training is tailored for sailors on all decks. So for instance, you have a submarine series, you have a surface ship series, large deck series, and then you have a group training series. And the reason for breaking them apart like that is to provide different workouts for the specific environments that sailors are exposed to. Fitness leaders like the straightforwardness of the workout program. It really takes all the guest workout. You don't have to schedule your workouts. All your workouts are planned for you. You don't have to worry about equipment being available. There's a lot of body weight exercises. So regardless of what you have on hand or how much time you have, there's a workout you can do. After a full day of training, these CFLs and ACFLs are NOS-perficient, ready to get their sailors fit and fueled. Petty Officer Shamir Purefoil, Yakuza Naval Base, Japan.
