This is my first post, so go easy on me. I am a 20 year old male. I am currently going to college part time, as well as working at a part time job that I don't particularly enjoy. I recently ran into an old friend from high school; he joined the Navy after high school, and seems extremely happy and says he is having a great time. I have always been interested in the military, and this has only peaked my interest. The only problem is that I am terrible shape. I am 6ft and weigh 250 pounds, which according to the BMI scale, means I am technically obese. I cannot do either push-ups or pull-ups I am joining my local Planet Fitness, and I want to know what exercises I should do to improve my physique.
