People are too thin and want to keep fit. Can they still exercise at the age of 17 this year? I want to be strong and become a soldier (I don't want to disappoint my father)

17 years old is the golden age. Taking good exercise and laying a good physical foundation is a necessary prerequisite for being a soldier and making contributions to the country. Encourage you to keep fit, and you can achieve your goal under the guidance of science.

The most direct way to get stronger is to gain muscle. There are many factors that affect muscle growth. Such as living habits, diet, sleep quality, smoking and drinking, exercise and so on.

First of all, avoid unscientific living habits, don't smoke and drink too much, and stay up late less. Maintain regular and healthy living habits and schedules.

In terms of diet, eat three meals a day on time to avoid overeating. Eat more fresh fruits and vegetables, rich in protein food, etc. Eat less junk food, such as fried, high-salt, high-sugar and high-calorie food.

In sports, I often take part in outdoor sports, such as running (a combination of sprinting and long-distance running), push-ups, sit-ups, rope skipping, pull-ups, parallel bars arm flexion and extension, vertical jumping and so on. In short, run more and jump more.

Secondly, keep a peaceful heart and don't deliberately pursue short-term muscle growth. Do not encourage others. Training is a process from quantitative change to qualitative change, and muscle growth will only be reflected when it is accumulated for a certain training time.

Finally, perseverance is the most important thing. Don't give up halfway Scientific diet and proper exercise, I believe you can be strong and wish you health and happiness every day!
