175 60 kg？ Let's see, 1.75 * 1.75 = 3.0625, 60/3.0625 = 19.59. According to this coefficient, I don't know what your fitness purpose is. Since you want to eat protein powder, I can only be sure that you need to grow muscles to do this. Let me give you my opinion. According to your body shape, if you want to exercise your muscles clearly and give people a strong feeling, the coefficient should be raised to at least about 22.8. What you need to do now is to reduce fat content and increase muscle weight, that is, gain weight properly. Whey protein powder actually provides the repair function after exercise. After you do a lot of instrumental exercise and aerobic exercise, the capillaries of muscle tissue will be congested. Generally speaking, muscle growth is a tearing process, which is supplemented by protein powder. When this process is completed, the muscle lines will come out soon. I have been exercising for almost 8 months. After eating protein powder, muscle lines will come out in about 3 months. It looks very comfortable. I have a body mass index of about 23 now. Anyway, when I take off my clothes, my friends around me will say, Wow, it's so strong. But you are too thin now. It's no use just eating protein powder. Protein powder is used to supplement your physical fitness and protein after exercise. Only by supplementing protein will you look like Asan, the Indian long-handed player in Street Fighter. So protein needs to supplement carbohydrates and fats. Here I'll talk about muscle-building powder, which is actually made by protein. Carbohydrate and fat are mixed in a proper proportion for you to eat, and the effect is equivalent to beef (protein and fat). I'll give you a suggestion according to your situation. Protein powder should be supplemented every day after exercise 15 minutes, and you can only sleep after eating protein powder 1 hour. Eating protein powder without exercise is a waste, and uric acid becomes high. Never overdo it. When you are not exercising, you should eat chicken breast every day. That effect is particularly obvious. If possible, eat beef every day, eat less rice and eat fruits and vegetables every meal. If you make up, don't exercise, it is equal to 0. Sports is about science. Some people go to the gym to practice JB, but it doesn't work. I haven't been to the gym once, and my whole family is practicing, but I bought a book written by a Korean and read it once before it took effect. I didn't teach myself. Now I have some experience. The equipment investment is about 2,000 yuan. Do equipment exercise 1 three times a week, and do aerobic exercise for more than 40 minutes. Jumping rope at home is good. Stick to it for 4 weeks, and the muscle line day will be obvious. If it lasts for 8 weeks, it will basically take shape, lasting about 1 year. In summer, it is very eye-catching to take off your clothes and go shopping, especially to exercise your abdominal muscles. Now I am crazy about practicing abdominal muscles, because there is less oxygen, and the deposited fat blocks the abdominal muscles. Now I jump rope for an hour every day, trying to liberate my abdominal muscles as soon as possible. Come on, I hope it helps you.
