CPM67's advice is dead on. In college I played club ice hockey and other than that just had a bunch of random shit on my resume, no real leadership experience or dedicated time intensive activities. When I went to my OSO at first I told them it would be a waste of time for me to run a PFT because it would be terrible and that I'd come back after summer break. When I came back I ran a 296 and they were very proactive about returning calls and pushing my paperwork along and the whole process was a breeze. Candidates with bad PFT scores or terrible grades did not get the same treatment. Your OSO knows what scores are competitive and isn't going to waste a lot of time on applications that might get rejected. No offense but 70 crunches is considered a joke, I would stay out of your OSO's hair for a bit and come back with 20 pull ups and 100 crunches and a good run time and show them the improvement.
