why gain all that weight n muscle when your jus gunna lose it anyways... might as well wait til u become permanent party after all your training to get back into weightlifting/bodybuilding. all your gunna do in basic or boot is bodyweight exercises like push-ups, sit ups, pull ups, run, run, run, and your diet will be **** for awhile.. i'd say jus wait and start from scratch when u get to your first assignment..
just advice from a seasoned active duty soldier... take for what its worth
