Appropriately increase calorie intake and supplement high-quality protein: Thin people want to be strong, so you need to increase calorie intake, which can not only meet the body's metabolic needs, but also convert excess calories into body muscles.

The daily calorie intake of thin people is higher than usual 15%-20%. If your daily calorie intake is 2000 calories, your calorie intake can be increased to 2300-2400 calories when you gain muscle. In addition, we should pay attention to protein's supplements, such as eating more eggs, dairy products, lean meat, chicken breast, beef, milk and other foods. High-protein food can supplement the amino acids needed by the body and promote muscle synthesis.

Matters needing attention in weight gain

Friends who gain weight or lose weight should drink 3000-4000ML of water every day. Only by absorbing enough water every day can the body's metabolic function work normally and improve its nutrient absorption ability.

It is inevitable to exercise every day, and you don't have to go to any gym to exercise. As long as you keep exercising for 30-40 minutes every day, such as palm pressing and sit-ups (these exercises can be done at home), when enough nitric oxide is produced in your body, and when these "vital qi" freely spreads to every part of your body, your physical function will be gradually enhanced and your physique will be better and better.
