No problem man. If I may give one more piece of advice... Have him retake the ASVAB. I do not mean this is derogatory way at all, so please don't take it that way.
Have him study and retake it for a higher score. The scores are what determines his options in terms of jobs and schools both now, and throughout his entire career. This also comes into play if he leaves the MC and joins another branch or wants to go warrant or officer down the line. The recruiter may say those scores are high enough for what he wants to do, but you DO NOT want to be limited in your choices/options. Now is the time to study and retest while it is fresh in his head, not when he's in the fleet and wanting to drop a packet or go to a specialty school/follow-on training. There are various other scores within the ASVAB breakdown that also must be met for certain jobs. Best plan of action is to look at every job he even has a slight interest in and pull up the requirements. He can google this but the best way to get accurate info is to have the recruiter pull it up in the office.
Some will say that he can get an ASVAB waiver to attend a course/speciality school, but they are betting on a chance that may not exist. School seats are extremely competitive within the MC, unless you're on the unconventional side, which he doesn't qualify for due to his GT score. Many intel and tech gigs, sniper school, ranger school, MARSOC, etc all require 105 or higher GT scores to even be considered (anything 110 or higher is where you want to be in order to not be limited on the enlisted side). Even some SSPs won't accept you if you don't meet the 105 for school because it isn't worth wasting the platoon's seat on someone who doesn't meet the minimum requirements to attend school. While everything in the military is competitive when it comes to careers and professional development, no one comes close to the competition within the MC because of the limited resources and opportunities.
Lastly, 90% of recruiters are lying scumbags. Many didn't start that way, but the pressure that the greenie weenie puts on them to produce numbers (in an era and country that already has a low recruitment and retention rate) turns them into that. The recruiter will say anything to get you to boot camp. Even when you have stuff in writing, it can still screw you lol. I left AD and went into the reserves to do a different gig and I signed my bonus paperwork. Got all settled in and spoke with the admin peeps and sure enough, the MOS didn't have a bonus for the reserves (only active was getting them at the time). I referenced my bonus paperwork and they said that it wasn't valid or applicable. Don't the recruiters force your son into anything, even with seemingly small things.
While
@pmclaine is right to an extent, there is nothing wrong with hitting the gym prior. Muscle mass is usually cut (drastically lol) while in boot as he will be exerting way more than he consuming, that and boot camp isn't anything that strenuous (physically or mentally). I know that this may trigger the "back in my day" comments from some, but it isn't and wasn't. This goes back to my "boot camp stories shouldn't be a thing post boot leave" point. There are recreational adventure events that are more physically and mentally demanding that boot camp. That being said, what does matter is having a durable chassis that can move under load while keeping a clear head. Also, if he is planning on going combat arms, make sure he is incorporating some time in the pool swimming. This will also be a factor in terms of what opportunities he is eligible for in the future (if that's a path that interests him)...Plus comfort in the water needs to be a thing regardless.
Best of luck and trust me, push him to retake it to get that GT score up.
