I like to do every movement slowly and keep my muscles tense for a few seconds at maximum contraction. The most effective abdominal exercises are sit-ups and hanging legs. Abdominal muscle training, where gyms can be seen everywhere today, has a good effect.
Generally, I choose to practice abdominal muscles on days when I don't do aerobic training, and arrange it at the end of weight-bearing training.
Speaking of weight training, I want to emphasize that when training in other parts of the body, you must use heavy objects. Many people find that if you lift hard enough, you don't even need to practice abdominal muscles, because heavy training will force abdominal muscles to help the muscles you are training. No matter where you train, you should arrange at least one compound action using barbells and dumbbells (not combined equipment) for heavy weight training. Good examples are the upright barbell or dumbbell bending movement of biceps, the upright bending arm pull-ups movement of triceps, the upright barbell push-ups movement of shoulders, the squat movement of legs, the hard pulling and bending rowing movement of the back. Even if you practice chest, you must tighten your chest muscles and stabilize your torso.
A common phenomenon is that although the abdominal muscles are good, they are covered with a layer of fat. In this case, even doing thousands of sit-ups won't help, because all you do is to further exercise the muscles below, without burning the fat covering it.
First of all, you must realize that there is no such thing as partial weight loss. The only way to reduce fat and muscle is to implement a comprehensive plan consisting of reasonable diet, aerobic training and weight-bearing training. These three aspects work together and promote each other.
Proper diet can accelerate muscle growth; Aerobic training can improve metabolism, so as to use food more effectively and burn fat; Weight training can develop all your muscles, including your abdominal muscles, and help improve your aerobic metabolism and metabolism.
In order to lose any excess fat, you need to reduce calorie intake, change your eating habits, turn sweets and simple carbohydrates into protein and fresh vegetables, and don't be partial to food or fall into personal hobbies. The interval between two meals should be regular, and each meal should be balanced in nutrition, which can just relieve appetite, not fill the stomach.
Arrange time for aerobic training. Relaxing aerobic training can be a half-hour to one-hour walk three times a week, or it can be carried out on the training equipment in the gym. Aerobic training is best arranged on days when no weight training is carried out. You don't need to work hard, you just need to increase your heart rate by 65-70% of the highest value, which is about 120 times per minute.
The three aspects of abdominal muscle training should be arranged in a balanced way, not extreme. If you don't want to poop in the mirror or grab a handful of meat at your waist, do it quickly!
