My DS is going to USAFA summer seminar this June, and will take the CFA while there. My DS is a cross country runner and his pull ups and push ups are not as high as they could be. On the USAFA web site it says 12 pull ups and 67 pushups for males to pass the CFA. Is this written in stone? Can he opt out of the CFA at SS. Does anyone out there know of a good exercise regimen that could help him with his upper body ?
