Lucas- Are you prior service? That may allow you to still apply over the age cutoff, as long as it was an honorable discharge. Apply anyway, and get a waiver as necessary. Badger the recruiter -they often prioritize based on likelihood of completing the application. At MEPS you have to duck-walk at your physical, and other calisthenics. I go active duty this summer as FNP so I run daily, plus with a run-club once a week, all to make sure I'm in shape. Can you run 1.5 miles? That's pretty tough to do if you don't run every day and you're getting up in age. Why don't you join a running club to get in shape? Don't forget push-ups and sit-ups!
