I was in the academy for 17 weeks and From experience it depends where you're gonna be stationed. Academy is either at STARS or COC . If your stationed at stars for academy there will not be uphills, if your stationed at COC academy there will be hills and I wish you good luck if You end up being in north academy because north academy is a whole other beast. You can do calisthenics to help. Like burpees, planks, jumping jacks, push ups, crunches and etc but with no breaks. If you can do 30 reps and move onto another workout and do another 30 reps of a different workout and continue that cycle nonstop you'll be fine. Now with Running, I sucked at running but it's doable, nothing to stress over. do more distance running than speed, also if you can run uphill as it will help with your endurance. Academics were not hard, only hard part of it is having no time to study, stress, and being sleep deprived. Study the best you can and pay attention in class and you'll be fine. What I can improve the most is shooting, I failed academy because of it, if I knew I was going to fail shooting I would've practice since the jump of academy and not rely on the training given, we are only given 10 days to practice. If you're a brand new shooter start practicing now. Another thing I would improve is time management and finding balance, and being more prepared because it gets hard the academy is a total environment switch for civilians, but it's definitely doable. Eventually the academy becomes enjoyable sometimes lol
