PFT consists of 3 mile run, 18 min = 100 points ( they deduct a point for every ten seconds over 18 minutes)
Pullups - each pullup is worth 5 points, 20 pullups max = 100 points
Crunches - each worth a point 100 points max
I believe the minimum is 225 or 250. I wouldn't be satisfied or confident with that though to be competative. Always shoot for 300!
