2. Constant tension: Keep the muscles of the whole group tense, don't let the muscles relax at the beginning or end of the action (don't be in a "locked" state), and always be completely exhausted.
3. Relaxation between groups: After completing a group of movements, stretch and relax. This can increase the blood flow of muscle, and also help to eliminate the waste deposited in muscle, accelerate the recovery of muscle and quickly supplement nutrition.
4, practice more large muscle groups: practice more large muscle groups in the chest, back, waist, buttocks and legs, not only can make the body strong, but also promote the growth of muscles in other parts. Some people only practice their arms without other parts in order to thicken their arms, which will make the growth of biceps very slow. I suggest that you arrange some large-scale compound exercises with a large amount of exercise, such as heavy squats, which can promote the growth of muscles in all other parts. This is extremely important. Sadly, at least 90% people don't pay enough attention to it, so that they can't achieve the expected results. Therefore, in the training plan, we should arrange five classic compound movements: hard pull, squat, bench press and push-ups.
5. Eat protein after training: During the 30 ~ 90 minutes after training, the demand of protein reaches its peak, and the best effect is to supplement protein at this time. But don't eat immediately after training, at least once every 20 minutes.
6. Rest for 48 hours: You need to rest for 48 to 72 hours after the second local muscle training. If high-intensity strength training is carried out, the interval between two trainings of local muscles is not enough, especially large muscles. But the abdominal muscle is an exception, which is different from other muscle groups and must be stimulated frequently, at least four times a week, each time about 15 minutes; Choose three exercises that are most effective for you, and do only three groups, 20-25 times in each group, all exhausted; The time interval between each group should be very short and should not exceed 1 minute.
