I will be in the army next year and i need a fitness routine to get me in top shape for it so i am not absolutely dying when i start.
Get online and print out a training program for a mini marathon. Start training for it and you will be amazed at how fit you get. Within 2 weeks I was running 6 miles at a time.
Along with that, just work on your calisthenics. Be sure you can do lots of push-ups, jumping jacks, and sit ups!
Good luck!
