Army Physical Fitness Test (APFT)
When pushups are done your feet should be together or up to 12 inches apart, you can rest in the up position but can not touch your knees, you can not lift your hands, or feet off of the ground at anytime- duration of 2 minutes, no pausing or restarting.
Situps are to be done with someone holding your feet with only their hands (they can not use their knees to help keep you down). Your hands have to stay behind your head and your fingers must be interlocked. Your head has to go past your knees and your back has to touch the ground. The rest position is the up position and if you lay on the ground without making an effort to get up then the test is over- duration of 2 minutes, no pasuing or restarting.
2 mile run: self explanatory!
Currently I score 72 for pushups, 81 for situps, and 56 for the run.
