First of all, exercise should highlight anaerobic. Thin people only need to warm up 10 minutes to exercise aerobics. It is very important to do aerobic training, which is also what people often say about strength training. Don't be impatient at first, start with skilled use of equipment, then gradually increase to the maximum weight according to the body's endurance, and stimulate the growth of large muscle groups such as back, arms, abdomen, chest and thighs through training such as hard pull, pull-ups, bench press and weight lifting.
Second, eat more meals. The main reason for being thin is eating too little, that is, not enough calories. You can eat five to six meals a day, especially before and after exercise. You should focus on some foods rich in carbohydrates and protein, such as rice, noodles, steamed bread, potatoes, sweet potatoes, egg whites, chicken breast, beef and shrimp.
Third, sleep is prominent and adequate. Adequate sleep is important for gaining weight. Because all the auxins needed by human muscles are secreted at night, the recovery and synthesis of muscles are also completed during sleep. The average person sleeps seven hours a day, and it takes a thin person eight hours to get fat.
To sum up, thin people need three conditions to be fat, one practice, two eating and three sleeping. As long as these three conditions are met, you can't be fat!
