There is a military training before joining the army, especially physical training. I am in poor health. In case of military training failure, how to enhance physical fitness?

If you want to strengthen your physique and ensure that you pass military training, there is no shortcut. I suggest two points: first, strengthen the training intensity. When others rest, they have to rest less and practice more. The second is to strengthen the difficulty of training. According to the requirements of subject training, we should be strict with ourselves from difficulty and gradually increase the difficulty. I believe there will be obvious improvement soon.
