This question is for Airborne graduates. Are there any good workout routines that you used to increase fitness prior to school?

Oh yeah, and do some neck muscle isometric exercises with a buddy. I remember My neck muscles were really sore in the second week from all the check canopy movements wit a helmet on. It is surprising what a difference a 5 pound helmet makes.

I went to jump school a long time ago. If I remember right, we were still doing the 5 event PT test: run dodge and jump, inverted crawl, horizontal ladder, push-ups, sit-ups, and then the 2 mile run. I did the test nearly every day, not full bore, and added pull-ups to get in shape for airborne school. I worked for me. The point is, you need to be in good shape to get thru the course, and have excellent strength, not to bull thru things, but to prevent injury.

Airborne is easy.

Be able to run, do push ups and sit ups, 6 pull ups to army standard and be capable of doing a 4 mile run at 8 min miles aka slinky run and your fine.
They also have "adjusted female standards". I think all you need is a 30 second hang on bar but if you want to excel and impress your fellow classmates, meet the full standard and meet what the standard is for 19-22 year old men. You will be fine. It's easy

I don't think PT at Airborne was hard at all, even being 32 at the time and having to pass at the 17-21 Army standard. Just do the regular stuff, push ups, pull ups, sit-ups and run. Big fan of CrossFit and running for long term maintenance

Run, run, run, pushups and pullups!! Good luck!!!

Airborne school back in the day (1990) required allot of running everywhere, core strength to help control your body through Parachute Landing Falls (PLF's) and upper back strength o pull the risers to cotrol your direction and rate of descent. I think the hardest part of Airborne School was the repeated beating your body took practicing PLF's but there is nothing to do for that. I recommend lots of running, pull ups, leg lifts and core excercises.

It is an overall fitness. Running is paramount.
I was lucky, I went to Airborne School after Infantry School.

Pull up and run alot

Basic Training. I went right after. Not sure if they still run in boots. If so, might want to get used to it. If not...insert the requisite "everything was harder back in the day" rant here!

Just walk out the door....but running helps
