When you think of biceps curls, you might think of a muscular guy in the gym muttering while lifting a huge dumbbell. However, if done well, the biceps curl is one of the simplest weightlifting exercises, and it is valuable to anyone looking to increase or maintain arm strength and muscle tone.The key is to focus on the right technique instead of trying to maximize weight and let your form break down in the process. Make sure to maintain balance by exercising the back of your arms evenly, such as triceps exercises.
Biceps curls mainly target the biceps, brachialis, and brachioradialis. When the forearm is supinated (palms up), the biceps are stronger when the elbow is flexed, and when the forearm is pronated, the biceps are weaker. Brachioradialis is most effective when the palm is inward, and the brachialis is not affected by the rotation of the forearm. Therefore, the degree of forearm rotation affects the degree of muscle recruitment between the three muscles.
Biceps training = doing curls
The reason why this formula can be spread is not only because it is a summary of the experience of bodybuilders, but also because it is backed by scientific data.
In the electromyography (EMG) test, when the forearm rotates outward so that the palm is facing you and the elbow is bent, there is an obvious electromyographic activity in the biceps.
The curl includes the two characteristics of external rotation of the forearm and bending of the elbow, so it can be said that the curl is the most effective exercise for the biceps.
If you want to exercise the biceps more simply and effectively, you can look at the function of the biceps.
The biceps muscle is divided into long head and short head, both of which are connected to the shoulder joint at one end and the elbow joint at the other end.
Its role is:
Bend the elbows and externally rotate the forearm (the palm is facing you) to help the shoulder joint raise the arm.
Choose a dumbbell that you can lift 10 times. The recommended starting weight is 5 pounds or 10 pounds per dumbbell. If you have just started, recovered from an injury, or resumed exercise after sitting for a long time, you can start with 2 pounds.
You think you are cheating to get high scores, but it is in vain. Many people will unconsciously move their backs back when lifting heavy barbells, relying on the inertia of the body, or relying on twisting the body to save effort, just like cheating on a test. You will get a report card of vanity and feel good about yourself, but it will actually be of no use to you!
It only saves energy for a while, but it may damage the joints. In certain training barbell curls, the arm is not fully straightened due to weight, which may have some effort-saving effects. But this does not have the effect of exercise, and it will also put a burden on the joints.
In severe cases, it will cause injuries. When lifting a certain weight of barbells and dumbbells, because the body is not fixed, the muscles in the core area will relax, and the shoulders and wrists will bear excessive weight distribution. In severe cases, it will lead to injuries.
The forward movement of the forearm is the phenomenon of excessively lifting the equipment upwards when doing a curl, which causes the forearm link and the elbow to tilt forward, which is wrong.
The brain can keep up, but the joints can’t keep up. In the later sets of curling exercises.
It may be exhausted because of excessive physical exertion, but I want to complete the target training plan in my heart, so when I do the last few moves, I will suddenly speed up, thinking about completing it quickly. But this will disrupt the muscles and joints that have previously been adapted to maintain a certain frequency of movement, and the sudden acceleration of muscle stimulation may cause the risk and possibility of joint injury.
This exercise is usually recommended to most people. However, if you hurt your arm or feel pain during the exercise, please do not continue. After a few weightlifting, you may feel tired and even burn in your biceps and forearm muscles. This is what you need to strengthen and grow your muscles. However, once you are unable to curl your hair in a good form, please do not force additional repetitions. Take a break before doing the next set.
Don't lift heavy weights at first, stop if you feel any pain. Biceps exercises are very popular but don't rush to gain weight until you are ready. The elbow or wrist may be injured, which will affect your entire exercise routine.
