1. Different types of muscle fibers: Muscle fibers in human body are mainly divided into slow muscle fibers and fast muscle fibers. Slow muscle fiber is mainly used for long-term low-intensity exercise, such as jogging and swimming. Fast muscle fibers are mainly used for short-term high-intensity sports, such as weightlifting and sprinting. Bare-handed fitness mainly relies on repeated actions of rapid contraction and relaxation to stimulate the growth of fast muscle fibers, so it is difficult to train large muscles.
2. Insufficient training intensity: If you want to build large muscles, you need enough training intensity. Although unarmed fitness can exercise the whole body muscles, the training intensity is relatively low, and it is difficult to meet the needs of building large muscles. If you want to increase the intensity of training, you can try to increase the number of times in each group or increase the difficulty of training.
3. Dietary factors: In the process of muscle gain, a reasonable diet is also very important. Protein is the foundation of muscle growth, so it is necessary to ensure adequate intake of high-quality protein. In addition, carbohydrates and fats are also the main sources of energy and need to be taken in moderation. Only by ensuring a balanced nutrition can we provide sufficient energy for muscle growth.
4. Recovery time: Muscle growth needs enough rest time. If the training is too frequent, the muscles will not be fully recovered, but will lead to muscle fatigue and growth retardation. Therefore, reasonable arrangement of training and rest time is helpful to muscle growth.
5. Genetic factors: Everyone's genes determine the speed and potential of muscle growth. Some people are born with good muscle growth conditions, even if they exercise with their bare hands, they can build large muscles; While others are relatively difficult. But even under unfavorable genetic conditions, through scientific training methods and efforts, the ideal effect can still be achieved.
