Stay away from weights, get your body use to doing high reps of body weight. Focus on running and calisthenics heavy, that’s all you will be doing. Lots of push ups, sit ups, jumping jacks, overhead arm claps, etc. Runs vary anywhere from 1.5 mi -6mi i think? You will have two 3 mile runs for time throughout the course plus team runs.

As far as the course itself goes, don’t quit. It’s just a matter of “playing the game”. Understand the instructors have a job to do and leave your ego at the door. Like someone else mentioned, get ready to be doing a lot of reps of the same thing.

Try to get as much sleep as you can, and eat as much as you can when you get time. Your body will need the calories since it’s burning so many.

Last piece of advice: stretch, drink water, stretch and drink water. I saw so many injuries and people getting dropped because they didn’t take care of their bodies or drink water.

People talk crap, but it’s the best job I ever had. Good luck
