Well, I dont recomend anyone looking to go into the military to get on gear until they are in.
Before you have passed selection all you need to concentrate on is cardio, bw exercises, functional circuit training and compound lifts... So If I were you I would be hammering all of that and hopefully the gear you are currently running will at least get you a few more pullups!
I would also get and AI and HCG now and then plan to PCT off with nolvadex before you go away... You dont want low T during selection and I dont think Nolvadex is on the kit check list...
Loads of guys think getting jacked is the best way to get in the military, it isnt, its the opposite. The people who do well can eat shit food and little of it, and run for a very very long time while still being able to haul themselves over a few obstacles.
You get jacked when you are in, when the sleep deprived hell is over and you got hours each day to chill and hit the gym.. apart from on tour or exercise of course.
And how do I know this? Becuase I was the gym rat on Royal Marine Commando selection... And I sucked lol. Obviously smashed the pull ups press ups etc, but you try being a gym rat and then being woken up at 4am, given some chips for breakfast and then trying to yomp 30miles in kit over rough terrain... with no protein breaks!
