Ok a little introduction of myself - yeh time to fast foward for you I guess Im 18, 19 in august and from now till starting a college course in september I can do nothing but go for a job, but instead I've been looking into joining the TA (initially) for the lifestyle and experience that I wouldn't experience anywhere else outside the army. But I've just recently noticed the RMR, I have always wanted to be a royal marine since I was pretty young, but for some reason I didn't. And I don't want to join regular because I would feel guilty on the effect it would cause on my girlfriend. I understand it takes a hell of a lot of determination and guts to join the RM/RMR, but I really want this, I've done bugger-all (excuse the language) for the past year or so after finishing school and I just wanna prove something to myself and have self-discipline. Is it possible for me to go from sub-par fitness to being able to pass the RMR training within 4-5 months? This 4-5 months can be fully dedicated to fitness since like I said i'm not starting college till september. I'm 5'8 and 11.5stone, which doesn't really make my BMI too huge but my running is abysmal. I can barely do half a mile before having to stop! my upper body strengh is a fair bit better though, I do boxing and can do about 40-50 pressups, not impressive I know but deffinately not lagging as far behind as my running! I'm still in the stage of either joining the 266 cdo royal artillery battery (TA) in bristol or get fit enough for the RMR Bristol. In terms of determination for it, I've done nothing since I've left school really in terms of anything life changing so this will be a BIG turn-around. And would be a great tribute i think to my grandad who was a Royal Marine but unfortunately never had the fortune of meeting. Any info and tips will be welcome.
