I am a male, with a height of 175cm and a weight of 63kg. I want to develop abdominal muscles and chest muscles through fitness, and I want to know what methods and equipment can be used to achieve it. You need to gain weight at least 10kg. Muscle training cannot be localized unless you are a late professional player. Be sure to exercise your whole body and every muscle. With a large number of protein's supplements, it is possible to have an effect. If you work hard, it is estimated that you can achieve the desired results in about 2 years. Heavy weight, few times. Mainly instruments. You can't just do sit-ups and push-ups Remember. Otherwise, the body will lose its balance. If economic conditions permit, please join the gym and supplement protein powder and muscle powder appropriately. Trx fitness belt and rope are recommended for family fitness, and the effect is super good. Practice 3-5 times a week, that is, it is best to practice every other day, eat less and eat more meals, and pay attention to balanced nutrition.
