I believe he said....RANGERS!!!!
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.
