How should I train for 160th SOAR?

It takes time. When I went to basic training, I was 31 years old. I could run a 12-minute 2-mile but I could not max out my pushups and situps. What I did for myself, aside from working out, was to do or give myself the APFT before I started to work out. Basically, try to max out the push-ups or do as much as you can for push-ups and sit-ups. You can always find some place in the gym to lock up your legs or you do it home by going up against the sofa and putting somebody to sit there or put a couple dumbbells for counterbalance. After I maxed out my push-ups let's say I did 80, I would rest 2 or 3 minutes and then try to do 40 more for a total of 120. Same thing with the sit-ups if you need to do 80 sit-ups, do them and then do 40 more after a few minutes rest. Then do the 2-mile Run by running 8 laps at the track. What I'm talking about is when you have reached your goal of getting 300 or 270 or whatever. If you could do that about once a week, you'll be set. But before you get to the level you want to be, you may have to adjust be patient and allow your body to rest. I mean getting enough sleep. I mean going to the gym and running once all the soreness is gone. Sometimes that may take up to 3 days. That's for me. I'm sure there's some CrossFit or other kinds of workout routines you can do. Just my personal opinion.

Lat I heard they were still able to pick WHO they wanted, they are the cream of the crop, and few folks make up to their level.

Agreed, it's going to take time, but your heart has to be there from my understanding a lot of it comes down to you and you have to ask yourself do you want to be there? because if you dont you wont make it. I could be wrong but it's my understanding schools and groups like these want to see you work as a team more than anything else. So on an end note if you really wanna go to 160th then you're going to have to have the initial fortitude to go out and work on what you need, if its push ups then knock out 20 to 25 push ups an hour it may not seem a lot but by the end of the day you're going to have well over 150, same with the sit ups do 25 every hour, and for the run go for a light jog or do sprints depending on if you need to work on speed or endurance. I hope this helps, I just submitted my packet and also leave for ranger school this month so good luck and I hope to see you in the 160th. Take care.
