The standards are really not that hard for someone who works out regularly. Which, if you’re joining the army you should probably be going to the gym.

If you’re being drafted, chances are you had no desire to be joining the army.

Nobody's being drafted because there's no draft in US since vietnam war

Are you registered for Selective Service? If a draft occurs, which is likely rare but certainly possible under current circumstances, your options will be flee the country or elect conscientious objector status and experience whatever treatment you will experience from doing so.

Presumably a 42 year old who can meet the fitness tests will be a better candidate than a 25 year old who cannot. Less 42 year olds will be able to meet the requirements, but the ones that do are what they’re after.

Note that fitness standards are bracketed by age, so the standards themselves get more lenient as age increases. The standards in question: https://www.goarmy.com/content/dam/goarmy/files/HQDA_EXORD_2...
