I'm in good shape, and pretty strong. How tough is Marine basic training? been an athlete all my life, so I'm not some fatty. and before going into basic training what do you guys think I should be able to do before i go? i mean like run 10km, or do 100 pushups type of thing. but waking up at like 4 am or whatever it is, is going to piss me off more than anything...if i choose to enlist and whats the hardest part of the training?
