First of all, you should have enough sleep, and a balanced diet is the best guarantee for you to gain weight and muscle. If you break down your diet and train/recover, 56% to 60% of your calories come from carbohydrates and 25% to 30% from fat.
The main compensation means to promote recovery is to eat foods containing vitamins B and C. Vitamin B helps to absorb protein and various amino acids, and vitamin C helps to improve the immune system.
About diet:
Dietary nutrition is essential for everyone, and people engaged in bodybuilding training need adequate dietary nutrition. Only a reasonable diet and scientific training methods can beginners achieve the best training effect. There are seven kinds of nutrients directly related to human body structure, especially healthy bodybuilding: protein, fat, carbohydrates (sugar), minerals (minerals), vitamins, water and fiber. These nutrients have their own functions: training "lubricating oil" vitamins, minerals, "medium" water for discharging waste and regulating temperature during training, "fuel" fat for providing training energy, carbohydrates (sugar) and "cornerstone" of bodybuilding. Protein should scientifically absorb the following five groups of dietary nutrition.
Low-fat cereals, potatoes, beans (excluding soybeans) and nuts mainly supply starch, followed by protein, minerals and vitamins, and are also the main sources of dietary fiber. Intake should meet the needs of physical consumption of trainers.
Meat, fish, poultry, eggs and soybeans (including nuts with high fat content) mainly supply high-quality protein and fat, as well as some minerals and vitamins. The biggest difference between the two is the quality and quantity of fat. Generally speaking, plant fat contains higher unsaturated fatty acids, while animal fat contains higher saturated fatty acids (fish contains less fat). This kind of food can provide high-quality protein and supplement the necessary energy in the form of fat, so it is essential in the daily diet of trainers, and its dosage is100-200g, of which animal food and soybean or bean products preferably account for 50% each.
Vegetables and fruits can mainly supply vitamins, minerals and fiber. They can increase food intake, promote intestinal peristalsis, and facilitate digestion, absorption and excretion. It can reduce the catabolism and excretion of cholesterol (very beneficial to reduce hypercholesterolemia and prevent arteriosclerosis). This kind of food should be mainly leafy vegetables, with a daily intake of about 0.5 kg.
Milk and dairy products can mainly provide high-quality protein, fat, fat-soluble vitamins, vitamin B2 and calcium.
Oil can mainly supply heat energy, unsaturated fatty acids and some fat-soluble vitamins. Although animal fat can be completely replaced by the second food, vegetable oil is essential because it is the main source of unsaturated fatty acids and an essential auxiliary material for cooking.
Ideal dietary structure
The ideal dietary structure is that protein accounts for 25%~30% of the total, and carbohydrates account for 55%~60% of the total. Protein accounts for 25%~30% of the total, and carbohydrates account for 55%~60% of the total.
According to different physiological characteristics and training objectives, arrange special nutrition and recipe combinations. On the other hand, beginners can make special nutrition arrangements and recipe combinations according to different physiological characteristics and training objectives. It should be noted that in
Beginners generally don't need extra nutrition after getting a balanced diet. Too much nutrition is harmful to training. For example, obese people should consume at least 1g of protein per kilogram while choosing "diet food" and controlling their food intake, so as to ensure the basic needs of bodybuilding training. People who are weak should pay attention to supplementing fat and sugar foods in moderation to increase muscle energy storage.
The proportion distribution of five meals during the eclipse, the intake opportunity before and after training
Breakfast should account for 20% of the total, breakfast (between breakfast and lunch) should account for 65,438+00%, lunch should account for 30%, lunch (between lunch and dinner) should account for 65,438+00% and dinner should account for 30%. Food can be digested and absorbed by using the "five-meal eclipse method".
The interval between training and eating is generally small to moderate exercise, and you can eat after half an hour's rest; If you do a lot of exercise, you should rest for at least an hour before eating. At the same time, we should also pay attention to diet and give a reference to the diet plan for one day:
1. Breakfast at 8 o'clock, skim milk 250ml, proper amount of vegetables and fruits, 2 slices of whole wheat bread and 2 egg whites.
2. Add a banana at 10: 00, and properly supplement foods rich in protein and cellulose.
3. Lunch 12: 00, staple food 200g, meat 150g, vegetables 150g, and appropriate amount of fruit.
4. 15: 00, properly supplement foods rich in protein and cellulose.
5. Dinner 18: 30, staple food 200g, meat 200g, vegetables 150g, and appropriate amount of fruit.
6.20:30 meal, one fruit, two pieces of bread and three egg whites.
For fitness, it is through various forms of physical exercise and the use of various instrumental and non-instrumental action training to make people healthy and strong, promote the muscle development and symmetry of various parts of the human body and enhance the functions of various internal organs, especially the cardiovascular system.
The general exercise mode is the combination of aerobic exercise and anaerobic exercise, and the combination of unarmed exercise and instrument exercise. In the exercise, according to different parts of the body and organ system, carry out various methods and times of exercise. This is a whole-body exercise process, not just to exercise a certain muscle, or several muscles. Exercises for various parts of the body mainly exercise the big muscles of the back, chest, abdomen, legs, hands and other parts ~
To start fitness, you need to warm up fully first. First do low-intensity aerobic exercise, jogging, cycling, etc. About 20 minutes. Through aerobic exercise, your body will gradually get better, your body temperature will rise slowly, your heart rate will increase, and your breathing will become faster at a constant speed. Blood circulation is also faster, so that oxygen and nutrients will be transported to the heart and muscles to prepare for your exercise. Then, it is necessary to fully exercise the joint ligaments of all parts of the body and stretch the muscles of the limbs and back.
Then you can do anaerobic exercise.
Because strength training is intensive, consumes a lot of energy, and bears a heavy burden on nerves, we must pay special attention to recovery after training. Generally speaking, after bodybuilding training, under the condition of adequate nutrition and good rest, the body needs to recover to 90% 18 hours, and it takes 72 hours to fully recover. If you do the second training without fully recovering your muscles, the effect will definitely be bad. If this continues, it will also cause muscle stiffness and fatigue, which will greatly reduce the training effect. Generally speaking, practice 1-2 hours three or four times a week, and then pay attention to proper nutrition ~
The following are exercises for each part for your reference. I don't know if you have dumbbells at home, but it would be more convenient if you did:
(Again: For beginners, pay attention to the following points:
1。 Progressive overload rule: The basis of enhancing any health quality is to make your muscles undertake heavier tasks than before, and let them bear more and more loads. Specifically, it is to gradually increase the weight and density, but it must be gradual.
2。 Multi-group practice rule: every movement needs multi-group training, so that every muscle group can be thoroughly exercised. Generally 3-4 groups, each group is 8- 12.
3。 The law of chaos and unpredictability: that is, the law of changing motion It is to avoid the adaptability of muscles and often give them new stimulation.
4。 Rule of isolated exercise: for the muscle parts to be developed, try to bear the load alone to stimulate the muscles without the help of other parts.
5。 Priority training rule: for the weakest or key parts of the body, arrange them at the front of the training class to ensure the training amount with sufficient energy and physical strength. )
Monday: chest, waist and abdomen muscle exercise
Chest exercises:
* * Push-ups. 15-20 (times) x 3-4 group, which is the basic training method.
Push-ups are very effective for developed pectoralis major muscles and also have a certain effect on developed triceps brachii. Feet can be close together or shoulder-width apart. Exhale when the body descends, and inhale when supporting. During the whole exercise, the body should always keep a straight posture. You can also try different actions: relax the distance between your hands and practice the outside of pectoralis major; Raise your feet, keep your head low and your feet high (the angle should not exceed 10 degrees, otherwise your shoulders are not your chest), and you can practice the upper part of pectoralis major; Keep your hands as close as possible, and even do push-ups with your hands folded. You can focus on the triceps brachii and pectoralis major.
* * Bench-push bar dumbbell exercise, the most important chest exercise method, is mainly influenced by factors such as bell weight, bar grip mode, grip distance, lifting angle, lifting speed, group times, etc. The muscles to be practiced are mainly pectoralis major, and others include arm muscles and shoulder and back muscles. In the grip distance (the same distance as push-ups), it should be clear that:
1. Flat grip: indicates that the grip distance is the same as the shoulder width. It has the greatest positive stimulation to the chest muscles.
2. Wide grip: the grip distance is obviously wider than the shoulder, which stimulates the outside of the pectoral muscle to the greatest extent and widens the pectoral muscle.
3. Narrow grip: the grip distance is narrower than the shoulder, which is the biggest stimulus to the inner side of the chest muscle. The different grip distances mentioned above stimulate the pectoral muscles differently. Similarly, different grip distances will also affect the auxiliary muscle: triceps brachii, which depends on the angle of elbow and shoulder during exercise. During exercise, the greater the change of elbow angle (the angle between upper arm and forearm), the greater the stimulation to triceps brachii. During exercise, the greater the change of shoulder angle (the angle between upper arm and body), the greater the stimulation to chest muscles. Because many times when everyone is doing the same action, they find that the effect is different, but they can't find the reason. Or want to stimulate the pectoral muscles, but often when the pectoral muscles have no feeling, the hands (triceps brachii) are already very sour.
* dumbbell bench press 10- 12 (times) x3 group
/upimg 3/2005/ 1 1/ 17/0000 199967 . gif
A. Key exercise parts: pectoralis major, deltoid and triceps brachii.
B. Starting posture: Lie on your back on a flat bench with your feet flat on the ground. Hold the dumbbell with your palms straight up.
C. Action process: make the two straight arms open to both sides, slowly bend the arms, and the dumbbell falls vertically. When it drops to the lowest position, it will do push-ups and exhale when it is pushed up. Then push it to the open position and sit down.
D. training points: don't arch your back and hips, and don't hold your breath, which will make your muscles lose control and be dangerous.
* Tilt dumbbell bench press upwards 10- 12 (times) x3 group
/upimg 3/2005/ 1 1/ 17/0000 199978 . gif
A. Key exercise parts: upper part of pectoralis major, followed by toe of deltoid and triceps brachii.
B. Starting posture: Lie on your back on the bench and tilt upward for 35-45 degrees.
C. Action process: Hold the dumbbell directly above the shoulder with both arms. Inhale when lowering to the chest (near the clavicle). When descending to the lowest place, do push-ups and exhale when doing push-ups.
D. Training points: During practice, the main strength is concentrated on the pectoralis major, so that the pectoralis major is always in a state of tension. Triceps brachii as a secondary supplementary strength.
* parallel bars arm flexion and extension 10- 12 (times) x3 group
/upimg 3/2005/ 1 1/ 17/0000 19997 1 . gif
A, key exercise parts: mainly the lower part of pectoralis major, followed by triceps brachii and deltoid muscle.
B, starting position: the distance between the poles is better than the shoulder. Hold the pole with both hands as a straight arm support, hold your chest and abdomen, and keep your legs together, straighten and relax.
C. Action process: exhale, bend your elbows and arms, and lower your body until your arms bend to the lowest position. Your head should be forward and your elbows should be extended to fully stretch your pectoralis major. Inhale immediately, support your arms with the sudden contraction of pectoralis major muscle, and make your body rise until your arms are completely straight; When the upper arm exceeds the horizontal position of the bar, the hips are slightly retracted and the trunk is in a posture of "bow your head and hold your chest out". When the arm is straight, the pectoralis major is in a state of complete tightening. Repeat the exercise.
D, training points: the action should be carried out slowly, and don't use the vibration of the body to help complete the action; Hold up quickly, hold out your chest, raise your head and abdomen, and don't shrug your shoulders; In order to increase the training intensity, you can carry out waist weight-bearing exercises.
Abdominal training:
Let me show you two videos first, which I personally think are very good:

Other training moves (for you, try them yourself and use them alternately):
* Leg-rest sit-ups 15-20 (times) x3 group
/upimg 3/2005/ 1 1/ 17/0000200029 . gif
A. Key exercise area: upper abdomen.
B. Starting posture: Lie on your back on the ground, put your calves horizontally on the stool, make your thighs vertical to the ground, and cross your hands on your chest or behind your neck.
C. Action process: slowly bend the shoulder to the knee until the swollen bone of the shoulder is 1 ~ 2 inches from the ground, and keep still for one second. Then, return to the starting position. Do it repeatedly.
D. Training points: When bending and contracting, in order to better contract the abdominal muscles, make the lower back close to the ground. We should avoid using jumping and bouncing to help each lift when starting weight training courses.
* supine leg lifts 15-20 (times) x3 group
/upimg 3/2005/ 1 1/ 17/0000200030 . gif
A. Key exercise areas: lower abdomen and upper thigh flexors.

C. Action process: make the trunk and lower back close to the ground, slightly bend the knees, and lift the legs upward until the thighs are perpendicular to the trunk. Then, slowly lower your legs. Do it repeatedly.
D. Training focus: When the back is always close to the stool surface, make the abdominal muscles in a tight state. If the back waist bends or leaves the toilet surface, it will affect the contraction effect of the lower abdominal muscles. In order to strengthen the training intensity, you can also practice on your back on the inclined plate.
* sit-ups/file upload/2006411204618138.gif.
A. Starting posture: supine flat pad or supine inclined plate, head up. Hold the fixed object behind your head with both hands and straighten your whole body.
B. Action process: contract the abdominal muscles, and bend the legs that remain straight upward as much as possible. Hold it for a second, and then let your legs fall back slowly. Inhale when your legs are bent up and exhale when you fall back.
C. key points: when you fall off your leg, you should still control your abdominal muscles and don't fall too fast.
* Lie on your back, lift your legs and bend your upper body.

A. Starting posture: lying on the bed or on the ground. Bend your knees, lift your calves, don't let them fall, and put your head in your hands.
B. Action process: In the posture of keeping the calf down, try to curl the upper body forward, so that the body will not actually be lifted very high. Inhale when curling forward and exhale when leaning back.
C. note: when curling forward, the waist should sink, close to the bed or the ground, and the abdominal muscles should contract as much as possible.
* Hang the bar, bend your knees and shrink your legs
/upload files/20064 1 120502 14 10 . gif
A. Starting posture: Two hands hold the horizontal bar, and the whole body hangs straight under the bar.
B. Action process: bend your knees and try your best to retract your calf upwards. When reaching the highest point, completely contract the rectus abdominis for one second. Then slowly droop the calf until it is completely straight. Inhale when the calf contracts and exhale when landing.
C. note: try to lift your knees up when contracting your calves.
* Sit Leg/Upload File/2006411205039587.gif
A. Starting posture: Sit on the edge of the stool with your hands on the stool. Keep your legs straight forward.

B. Starting posture: sit or stand up straight, with the upper body slightly leaning forward, one hand dumbbell hanging on the inside of one leg, the elbow of the other arm naturally bending, and the palm or elbow resting on one thigh.
C. Action process: Hold the bell and slowly bend your elbow up to your chest. Don't move your upper arm, stick to the inner thigh.
D. training points: when holding the bell, don't relax your back. When the bell bends to the chest, make the biceps brachii as tight as possible and keep still for 3 seconds. Then, put it down slowly. You can also do it standing.
* 8- 12 (times) x 3-4 groups of sitting posture, oblique arm, back hug and bending.
/upimg 3/2005/ 1 1/ 17/0000 199944 . gif
A. Key exercise areas: mainly bodybuilding biceps brachii and other elbow flexors.
B. Starting posture: sit on a fixed stool, lean forward slightly, put your arms straight on the inclined plate, so that your armpits are stuck on the upper edge of the inclined plate, your fists are forward, and your hands hold dumbbells back shoulder width.
C. Action process: inhale, forcibly lift your arms around the elbow joint until the bell is close to the clavicle, pause for 2-3 seconds, then exhale, relax and restore your arms, and repeat the exercise.
D. training points: keep the upper arm still and stretch slowly and fully when bending the arm.
Straight man. Due to the limitation of the inclined plate, it is impossible to borrow the strength of other parts of the body when doing this action, so the training effect of biceps brachii is remarkable. But it is not suitable for beginners to do this action at first, and anyone who has reached the primary training level or has the primary training level can do this action.
* Standing dumbbell hammer bending 8- 15 (times) ×3-4 groups
/upimg 3/2005/ 1 1/ 17/0000 199950 . gif
A. Key exercise parts: mainly exercise the brachialis and biceps brachii.
B. Starting posture: upright or sitting posture, arms straight and naturally drooping, dumbbell in hand, tiger's mouth facing forward. C. Action process: At the same time, both upper arms bend upward around the elbow with dumbbells, forcibly tighten the upper arm and forearm, pause for 2-3 seconds, then exhale, slowly put down the bell and return to the side, and repeat the exercise.
D. training points: when holding the lever and swinging, the upper arms of the two arms are fixed, and the bell is held by the straight wrist, and the inertia force of the upper body swinging is not allowed.
Triceps brachii:
* Sitting posture, flexion and extension of the back arm of one arm neck 8- 12 (times) x 3-4 group.
/upimg 3/2005/ 1 1/ 17/0000 199906 . gif

* dumbbell prone rowing 8- 12 (times) ×3-4 groups
/upimg 3/2005/ 1 1/ 17/0000 19993 1 . gif
A. Key exercise parts: upper back muscles, especially latissimus dorsi and biceps brachii.
B. Starting posture: kneeling on the bench with one leg and one hand on the bench surface. Hold the dumbbell forward with the other fist eye, next to the pituitary gland. Stand with your other leg straight and your upper body bent forward until your back is parallel to the ground.
C. Action process: Hold the bell close to the leg side and lift it up to the shoulder or higher. When lifting the bell, concentrate the contraction force of latissimus dorsi. Then slowly put it down and recover along the original road. Do it repeatedly. Practice with one hand, and then switch to the other.
D: Training points: When the dumbbell is lifted to the highest point (shoulder height), the upper body slightly turns to the other side, which will be more conducive to the complete contraction of the back muscles.
* Side lift 8- 12 (times) x 3-4 group
/upimg 3/2005/ 1 1/ 17/0000200000 . gif
A. Key exercise site: the lateral middle bundle of deltoid muscle.
B. Starting posture: stand naturally, with dumbbells in each hand in front of the anterior pituitary, elbows slightly flexed and eyes forward.
C. Action process: Two hand bells are lifted to both sides at the same time until they are lifted to the head level. Then, slowly fall back to the original position along the original path and repeat it.
D. training points: in the process of lifting and releasing the bell, the elbow and wrist are always slightly flexed, which is more effective for the contraction of deltoid muscle. When the dumbbell is lifted to both sides, at the same time, the wrist is turned up slightly higher than the thumb until it is lifted to the highest position. When the dumbbell falls, the wrist turns back.
* Upright and raise 8- 12 (times) x 3-4 groups horizontally.
/upimg 3/2005/ 1 1/ 17/0000 199997 . gif
A. Key exercise areas: posterior deltoid and upper back muscles.
B. Starting posture: Stand with your feet shoulder width apart, hold dumbbells in the palms of your hands, bend your upper body forward and parallel to the ground, and bend your legs slightly, so that there is no tension in your lower back.
C. Action process: Lift the two hand bells to both sides until the upper arm is parallel to (or slightly beyond) the back, pause for a moment, and then put down the dumbbell to recover. Do it again.
D. Training points: If your elbow and wrist bend slightly when you hold the bell to both sides, you will feel that you can get better deltoid muscle contraction. During the whole exercise, the mind should focus on the contracted muscle groups.
* original 8- 12 (times) ×3-4 groups of the same elevator.
/upimg 3/2005/ 1 1/ 17/0000200003 . gif

B. Starting posture, standing naturally, holding a bell in each hand or lifting a barbell in front of your legs.
C. Action process: Lift the dumbbell or barbell forward (elbow slightly flexed) until it is parallel to the line of sight. Then, slowly put down the reduction and repeat it.
D. training points: if you use dumbbells, put your fist forward and hold the bell in front of you. This method is to concentrate on training deltoid toes alone.
Friday: leg muscle exercises
The general method is squat, but the intensity is relatively large. It is suggested to gradually increase the weight from light to heavy.
* Squat Weightlifters Squat 8- 10 times x 3 Group
/upimg 3/2005/ 1 1/ 17/0000200027 . gif

D: Training points: You can sit on the leg stretcher, practice on one leg, straighten your instep, or turn your heel inward or outward.
If the equipment is not suitable, you can also practice without the help of equipment. You can also practice leg strength through vertical jump training programs in the United States. Let me show you this training program, with online introduction and video. This is a tutorial. I have a classmate who is the defender of the amateur team in the city. Through this method, he made progress of 30 centimeters. He often strongly recommends others to practice like this.
