Basic
Dont worry to much sort your Phizz out plenty running and swimming and start doing loads off pushs build the upper body. Remmber its not the army your joinning so you dont have to be a gym monster. Expect loads off bull in your first few weeks lots off late nights bulling shoes and polishing everything that moves. Get your head around the fact your going to be sharing with loads off other blokes and get a sence off Humour thats your biggest tool when going through depot. But most off all enjoy it you will look back in a few years and smile about it. I was in the army and looking back now it was some off the best times off my life. Have a positve outlook to everthing and when things get ****ty remmber its just a means to an end.
GOOD LUCK.
