well as it says above im 18, male and im planning on joining the army, my problem is that im SUPER SUPER unfit, i'm 5 ft 11" and i weigh 14 stone 3lbs, not all fat though but tbh thr fat out weighs the muscle haha, any ways ill get back to the point. I am soon looking to do my fitness test which includes 1.5 mile run in under 11 minutes i think it is. NOW heres the embarrasing part, when i go jogging i jog for about half a mile if im lucky normally around about 0.450 miles coz i have one of them distance measuring things and im totally nackered!. My muscles dont ache its just my chest feels like its closing up and i get really out of breath. I take deep breaths and exhale slowly not too slow though lol. I am looking to join within about 3 - 4 months but to do that i need to improove my fitness alot, i want to be able to do about 3 miles before i go in so is their any chance any one could give me some tips on how to get fitter faster? please? and is their any suppliments i could take to help improve my fitness. im fine with my strength at doing other physical things its just jogging/running. thanks.
