Guess I'll have to explain a little bit more

I see your point, but I actually have a dream about joining the special forces (called Jęgerkorpset in my country), like a lot of boys my age - I'm 20.
I would, of course, start out slowly. Therefore I've made 5x10 kilo (22 pounds) sandbags, so that I can adjust both kilos and kilometers gradually. I'm in a pretty good shape, since I've always dreamed of a military career, but Jęgerkorpset (the special forces) recommend that you start march training with backpack early. I'm thinking about applying for admission in like 2 years.
So you see, I'm not really concerned about the basic training, but the training for Jęgerkorpset.
- I was just too lazy to give the full explanation the first time. Also, it was a bit more cryptic to write in english, since it's not my native tounge.
Hope you understood this though.
Thanks for the fast answear and sorry for the misleading first post.
