What is the physical activity at Navy Basic training? What do they do?

You spend the majority of your time running and marching. Things like pushups/situps are mostly used as punishment or "beatings" when you messed something up. You go through a quick swimming test that lasts a few hours but thats the one and only time you will ever get in a pool. Unless you fail the test, then youll have to take daily swimming classes throughout bootcamp. Thats about it, the worst is they constant standing, the only time youre allowed to sit is when you eat and sleep. So basically its all legwork
