Generally, protein needs to be replenished in large quantities at noon. Generally, the absorption rate in protein is 98% at this time.
And eat more fruits and drink more water to replenish water and increase muscle elasticity.
Here's how to practice muscles with dumbbells:
First of all, the chest
1. bench press: mainly practice the thickness of pectoralis major and thoracic groove.
Action: put the dumbbell on the bench with both hands, put the dumbbell on the shoulder, and palm up. Push the dumbbell up until the arm is straight, stop for a while, and then slowly recover. Tip: Push-ups and squats are curved, so that pectoralis major can be fully contracted and fully extended.
2. Pushing upwards: mainly practicing upper chest muscles.
Action: the action essentials are the same as those recommended for lying position, except that the stool surface is adjusted to an inclined angle of 30 ~ 40 degrees and leans on it.
3. Sleeping bird: mainly practicing the middle thoracic groove.
Action: On the supine stool, hold dumbbells with both hands, palms facing each other, and naturally stretch your arms over your chest. The elbow of the arm is slightly bent to lower the dumbbell to the lowest point on both sides, the pectoral muscle is fully extended, and the pectoral muscle is forcibly contracted to lift and restore the arm.
4. supine straight arm pull-ups: expanding the chest and practicing the best action of pectoralis major and serratus anterior.
Action: Lie on your back on the cross stool, with your shoulders on the ground and your feet on the ground. Hold one end of the dumbbell on the chest with both hands, and slowly put (put down) the dumbbell on the back of the head with the shoulder as the axis (feel the stretching of the chest muscles and chest). When it reaches the limit, lift the dumbbell to restore it.
Note: In order to prevent damage, the descending process should not be too fast.
Second, the shoulder
1. Push: mainly practice the deltoid.
Action: Sitting posture, holding the dumbbell with both hands to the side, elbow abduction, palm forward, pushing the dumbbell to the highest point in an arc, stopping for a moment, and slowly controlling the dumbbell to recover according to the original route (arc). Tip: You can also do it standing, with both arms at the same time, or with one arm.
2. Side lift: mainly practice the middle bundle of deltoid muscle.
Action: Hold two dumbbells in front of your legs, lean forward slightly, bend your elbows slightly, lift the dumbbells to shoulder height on both sides, make the deltoid muscle in the "peak contraction" position, pause for a moment, and then slowly control the shoulder muscles. You can also do it with one arm and rotate with both arms.
3. Bend over and lift sideways: mainly practice the posterior deltoid.
Action: Hold dumbbells with both hands, palms facing each other, bend over and bend your knees, stabilize your body, lift your arms to both sides, and then control them to decrease slowly.
4. Shrugging: Mainly practicing trapezius muscles.
Action: Hold the dumbbell beside you, bend your knees slightly, lean forward slightly, fully lift your shoulders, try to touch the earlobe with the shoulder peak, pause for a moment, and then slowly control the lowering.
Third, back
1. Bend over and paddle with both arms: mainly practice latissimus dorsi.
Action: Bend your knees slightly, hold dumbbells in each hand and hang them in front of you. Use the contraction force of latissimus dorsi to pull the dumbbell to elbow and shoulder height or slightly higher.
Above the shoulder, stop for a while, and then control the dumbbell to return slowly with the tension of latissimus dorsi. Note: when rowing, latissimus dorsi mainly contracts and stretches, and the upper body should not be lifted to avoid borrowing.
2. Bend over and paddle with one arm: mainly practice the outer back and lower back.
Action: Hold the dumbbell with the palm inward, and hold the fixture at the knee position of the same leg with the other hand to stabilize the body. Lift the dumbbell to the waist position (the back muscles are fully contracted), stop for a while, then slowly recover in a controlled way (fully stretch the back muscles), and then change one side to the other after completion.
3. Straight leg hard pull: mainly practice the lower back, gluteus maximus and biceps femoris.
Action: Hold the dumbbell with both hands and hang it in front of you. Your feet are naturally open, shoulder width apart, your legs are straight, your back is straight, your body is bent forward, and your head is raised until your upper body is roughly parallel to the ground. Then the lower back muscles contract and restore the upper body. Note: In order to maintain tension, the dumbbell should not touch the ground when leaning forward. You shouldn't walk too fast.
Fourth, biceps brachii
1. Alternate bending: mainly practice biceps brachii and separate biceps brachii.
Action: Sit (or stand), hang dumbbells at your sides with your hands, palms facing each other, elbows at your sides. With the elbow joint as the fulcrum, bend upward, at the same time, palm up, forearm rotate outward, lift to the highest point to tighten biceps brachii, pause for a moment, and then control the reduction. Do it in turn.
2. Mind bending: mainly practice biceps muscle peak.
Action: Stand, the upper body naturally bends forward, dumbbells are hung in front of the body, and the upper arm rests on the knee or leg on the same side. The other hand is bent on the same knee or leg to stabilize the body. The arm holding the dumbbell bends upward to the highest point, so that the biceps brachii contracts to the limit, stops for a while, and then slowly recovers.
3. Lateral bending: mainly practice the brachialis and forearm muscles.
Action: Sit (or stand), hang dumbbells on the side with both hands, palms facing each other, upper arm close to the side, elbow joint as the fulcrum, bend upward to the highest point, pause for a moment, and then slowly recover. Tip: You can do both arms at the same time or alternately.
Five, triceps brachii
1. flexion and extension of the posterior cervical arm: mainly practicing triceps brachii.
Action: Sit (or stand), hold one end of dumbbell behind the neck with both hands, palm forward, upper arm fixed, and bend and stretch with elbow as fulcrum. Tip: You can do both arms at the same time or alternately.
2. Bend over and stretch your arms: mainly practice the upper part of triceps brachii.
Action: Bend over, lunge forward and backward with your feet, hold your front legs and knees with one hand to stabilize your body, and raise dumbbells with your upper arms close to your body. The triceps brachii forcibly extends the arm backward and upward until the forearm is parallel to the ground, so that the triceps brachii contracts to the limit, pauses for a while, and then slowly recovers.
Six, legs
1. Squat: mainly practice thigh muscles and gluteus maximus.
Action: Hold the dumbbell with both hands and put it on one side of your body, or put the dumbbell slightly above your shoulders for smooth control. Feet naturally open about shoulder width, feet slightly open, chest out, waist and back tightened. Kneel and squat down to the lowest position, and then the thighs are forced to contract and squat down to recover.
2. Arrow squat: mainly practice gluteus maximus, biceps femoris and quadriceps femoris.
Action: Hold the bell with both hands, open your feet naturally, take a step forward with your right foot, bend your knees, and squat down with your hind legs almost close to the ground. After one leg completes the specified number of times, change to the other leg.
3. Prone leg bending: mainly practicing biceps femoris.
Action: On the prone stool, put the dumbbell on your feet or tie it to your ankles, with your calves suspended, hold the stool end with both hands and straighten your legs. Then the biceps femoris exerts force to bend the calf to the highest point, so that the biceps femoris is at the "contraction peak" position, stops for a period of time, and slowly recovers with the tension of the biceps femoris.
Seven, calf
Standing on one leg and lifting heels: mainly practicing calf muscles.
Action: Hold the dumbbell with one hand, hold the fixture with the other, stand on the pedal with one front foot, lower the heel to the lowest point as far as possible, and bend the other leg to lift the calf. The calf muscles contract hard, the heel is raised to the highest point, stop for a while, and then slowly recover. Do your legs alternately.
Teenagers had better not eat muscle powder, which is easy to cause renal failure! Eat more high-protein food. . .
Here are some high-protein foods:
High-protein foods include:
The food containing the most protein is soybean, which contains 36.3g per100g;
The animal that contains the most protein is chicken, which contains 23.3g per100g;
Protein-rich foods include: milk of livestock, such as milk, goat milk, horse milk, etc. Animal meat, such as cattle, sheep, pigs, dog meat and so on. ; Poultry meat, such as chicken, duck, goose, quail, ostrich, etc. Eggs, such as eggs, duck eggs, quail eggs and fish, shrimp, crabs, etc. ; There are also soybeans, including soybeans, green beans and black beans. Among them, soybeans have the highest nutritional value and are high-quality protein sources in infant food; In addition, the content of protein in sesame, melon seeds, walnuts, almonds, pine nuts and other dried fruits is high. Because the contents and types of amino acids in various foods are different, the contents of other nutrients (fat, sugar, minerals, vitamins, etc.) are also different. ) is also different, the above food is optional when adding complementary food to babies, and it can also provide children with high-quality food from protein according to local specialties.
The content of protein in beans, peanuts, meat, milk, eggs, fish and shrimp is higher, while the content of cereals is less, even less in vegetables and fruits. The human demand for protein depends not only on the content of protein, but also on the types and proportions of essential amino acids contained in protein. Because the types and proportions of amino acids contained in animal protein are more in line with human needs, the nutritional value of animal protein is higher than that of plant protein.
In plant foods, protein in rice and flour lacks lysine, and protein in beans lacks methionine and cystine. Therefore, eating mixed food can learn from each other's strong points and greatly improve the utilization rate of mixed protein. If animal protein is properly supplemented, the nutritional value of protein in diet can be greatly improved. Although the content of protein in human milk, milk and eggs is low, the content of essential amino acids is basically the same as that in human body, so it has high nutritional value and is the best food in diet.
Protein is an important substance that constitutes the human body and various tissues in the body-muscles, bones, skin, nerves and so on. Both contain protein. The material basis of growth is protein. Therefore, children should be given more food rich in protein.
Protein-rich foods include: milk of livestock, such as milk, goat milk, horse milk, etc. Animal meat, such as cattle, sheep, pigs, dog meat and so on. ; When birds add complementary foods to babies, the above foods are optional, and high-protein foods can also be provided to children according to local specialties.
The following is the content of protein per100g of food:
Oats 15.6
Lotus seed 16.6
Soybean 36.3
Broad bean 28.2
Pork (lean) 16.7
Pig heart 19. 1
Pig liver 2 1.3
Bean curd skin 50.5
Pig kidney 15.5
Pigskin 26.4
Peanut 26.2
Pig blood 18.9
Walnut 15.4
Beef (lean meat) 20.3
Mutton (thin) 17.3
Silver carp 17.0
Rabbit meat 2l 2
Chicken 23.3
Chicken liver 18.2
Duck 16.5
Sea cucumber (dried) 76.5
Eggs 14.7
Lobster 16.4
Food prices in protein are relatively expensive. Parents can mix several cheap foods together to improve the utilization rate of protein in the body. For example, the biological values of corn, wheat and soybean are 60%, 67% and 64% respectively. If these three foods are matched in proportion, the utilization rate of protein can reach 77%.
The key to fitness is persistence. Only persistence can succeed. By the way, drink milk in the morning and before going to bed (others are not allowed to copy my answers).
