Physical train like he is going to the Olympaics. Some strength training to would be a good idea. Army puts too much stress on cardio he can use the body mass. Run, run, run. Running a Marathon would be good. And he has GOT FOCUS. Many Want, Few are choose. You GOT to want it as bad as anything cause they will push you to the end and beyond. Good Luck to him and God Bless him. I will remember him in my prayers.
Connor is 5'7" and hard and wiry. (He's on my "about" page!) He has played football and been in wrestling, so I'm thinking he will be fine. His dad is a marine, and his mother was in the navy, so I think some of the desire for military training is inbred. He will do well whatever he does, because he wants to.
"...I will remember him in my prayers."
Thanks! I'll tell him!
