I'm 16 at my high school and think that I might join the Army once I get out of High School. I'm an 130 lb, 5 foot 7, cross country runner. My forte is running, and i'm not much of an upper body strength person. Any advice or instructions to train would be helpful. Also I've been looking around and this victory wall thing scares me, is there anything I can do to help with my fear of heights.
Basically any advice to get in good shape for BCT would be nice.
