If you want to increase your strength, eat more rice and pasta (mainly carbohydrates) after one hour, so that you can fully recover your physical strength, and your physical strength will naturally have strength!
If you want to gain muscle, you can eat more protein food, such as eggs, chicken, meat including soy protein (don't eat too much, it will cause kidney burden) and appropriate amount of rice and flour (carbohydrates).
Personal advice, eat more and eat less! Eat 4-7 meals a day (depending on your level of exercise)
