need advice about getting into shape

[dkm77]

hi
im 20 years old and im intrested in becoming an army ranger, but my main problem is losing weight. im about 5'10 200 lbs, now im fairly strong and that doesn't seem to be a problem for me, but running is a pain in the ass for me. i work out at the local gym and me and my room mate are going to get into amature boxing. i still have about a year or two before my obligations are met, and i can join. is there any advice you guys could give me to help. im not mamas boy and actually enjoy physical demanding activities, so any help is welcome.
thanks
