The Navy loved jumping jacks when I was in. The first day someone in our company had to do 200 of them. We thought that was a lot. Then we also started including "hello Dolly's' and by the time we left we were up to 1,000 jumping jacks. Thats right, I said a thousand. We had what was called "Deck Parties" Besides getting you in only slightly better shape the most important thing is that it prepares you to deal with the absurd.
Oh yeah, avoid this last day bootcamp scam. It happens after graduation when you get back to the barracks to get your stuff together. Another company commander will come into your barracks, while yours is, no doubt, visiting the other company and saying something like, " your CC is a great guy and you all owe him a lot for how he got you through this and made sailors out of you. Well, I'm a pilot and offered to take your chief with me on a little trip, but he's a little low on cash. It would really show your chief how much you want to thank him if I can collect some money from you sailors so your chief can take a little trip." People were dumping all kinds of cash into this guys hat. Save you money, it's bullsh_t.
