You will be required to take, and pass, a Physical Fitness Assessment prior to going to Initial Active Duty Training. You will take an initial PFA within 1 to 10 days of signing your contract at the MEPS. The Physical Fitness Assessment will measure your upper body strength by having you do push ups, your lower body and abdominal strength with sit ups, and your cardiovascular endurance with a 1 mile run. You will receive additional information about the PFA from your recruiter.
