Train like you've never trained before. Lots of upper body work; not just yomping around. Overhand pull ups a must. Remember to rehydrate ALL of the time, not just after running, this will help with endurance and recovery rates as the AACC involves a lot of attrition on your body. Learn how and where to tape your feet up. You might be lucky and never need to, but I doubt it. For the rope climb, some people used to use some kind of sticky substance used in racket sports to help you maintain friction when your hands are wet. Never did myself. Another one is to use kneepads for crawling around the Endurance Course. Again never needed to myself, but some lads swore by them.
Attend all of your commando training run by your unit and try and copy the type of training they put you through.
Have two pairs of well worn in boots.
And remember what you're aiming for, it will help through it all.
two questions as in my unit there is more chance of plaiting pi$$ than finding someone who's completed the aacc:
1, can you wear non issue boots?
2, whats the deal with weekends etc, do you get many, if any off?
