Run, run, run...Sit ups, Push Ups, Run, Run, Run...See a pattern forming?
Good that you are preparing for the physical side of things. Can't prepare you for the mental toughness you will need to find within yourself. Remember, don't take the comments personally, everyone in basic is a dirt bag! lol And that won't be the only name you hear.
Good luck and remember you aren't the first to go through it and won't be the last. Just learn to suck it up and drive on! HOOAH!
