Re: preparetion to join the army
Determination is going to be your best friend if you want to get into an elite group in the military.
First things first, start eating healthy NOW. Not tomorrow, not next week, but now. If you don't then your likely to keep putting it off more and that's counterproductive to your goal.
Second, get a good pair of running shoes if you don't allready have some and go jog/run every day gradually increasing your endurance as you get stronger.
Third, cross train. You'll need to be able to swim well in any elite branch of military.
Lastly, pay attention in school and keep your grades up! No military wants a dumb soldier doing their work.
A great thing to do to become more physically strong is to join teams at your school like Cross Country, Track & Field, and Swimming. In addition to that the system P90X is an amazing system with alot of success stories. I've not heard of one displeased customer that didn't lack determination to keep going. I don't know what requirements your military has but whatever they may be shoot for the highest score possible. Pushups, pull-ups, crunches/sit-ups, are all great places to start. And don't be discouraged if you can't do many right off the bat. You're only fifteen, im only sixteen, and if either one of us believes that we can't make it then we will not. But if we keep our determination and keep pushing foreward with our goals then eventually we WILL make it. Never lose hope and you'll do allright.
And keep a "NEVER quit" aditude(sp?) with all of these things and as a general rule through life and you'll do just fine. Start small and work your way up.
Hope this helps,
