text: how hard is it to get in shape good enough for going into the navy seals but it is the middle of the winter?? im 17 and weight 180lbs. help you're 17 years old and wet behind the ears.  don't you think it would be a good idea if you went through boot camp first?  either navy or marine corps boot camp will get you a lot closer to the seals, but first you have to complete that part of the journey.  the navy seals really aren't looking for 17 year old's to fill their ranks, they would rather have seasoned veterans who have been around the block once or twice.  so my suggestion to you is slow down, if you still want to be a seal once you are in and through training, go for it then.in the meantime get yourself ready for navy or marine boot camp.    by the way, regular boot camp, particularly marine corps boot camp,is not exactly a walk in the park, so get yourserlf in condition, it will make life a lot easier once you're in the thick of it.
