It's not a question of being a soldier or not. Some people in the army are forced to keep practicing every day. If you want to practice by yourself, you should also set a goal: do several groups of push-ups every day, and how many times each group has a rest. Abdominal muscles can do sit-ups. I recommend that you can practice abdominal muscle tearing after a certain foundation, and the effect is very good. Of course, practicing abdominal muscles can't reduce your stomach. Other exercise modes can be dumbbell hardware running up.
