People don't consider dumbbells to be very useful, just because They're common in many households and gyms. Lets find out how the arm muscles in our body work to see how dumbbells target our arms when we do workouts.

The biceps, or the biceps brachii, are responsible to rotate your forearms as well as your elbows, and finally to raise your arms in front at the shoulder joint.

* The Brachialis enables the elbows to be bent.
* The Brachioradialis enables the elbows to be bent and straighten.
* The Triceps help you straighten out elbows and brings the arm back to the shoulder.

Developing the aforementioned muscle groups will permit you to gaining arm strength and having easier mobility in your arms.

Training the Biceps Brachii

Developing the biceps can be done by doing supinating bicep dumbbell curls, which are also known as sitting bicep curls. Your palms will be facing downwards when you begin the exercise, but when its finished, they will be facing down. This exercise works most efficiently if you place the bench on an incline.

Training the Brachialis

A small ball of muscle is located at the side of your upper arm. When you flex your elbow completely, you can locate it. Its call the brachialis muscle. These muscles also tend to make the biceps seem larger because they lie right under the biceps. Also, they make your shoulders appear broader. Perform the dumbbell curl to develop your brachialis muscles. You can do it by placing your forearms halfway between the palm up and palm down position. The hammer curl is another name for this exercise.

Training the Brachioradialis

Most upper body exercises feature using finger and wrist extensors and flexors of the forearms, requiring a sort of gripping technique. Even though these exercises are very useful, they don't target the brachioradialis and upper forearm muscles properly. When you fully develop your brachioradialis, they will make your forearms seem much stronger, just like lats make your back look stronger. Doing the dumbbell curl will target your brachioradialis as long as your palms face down. Another term for this exercise is the reverse dumbbell curl.

Training the Triceps

Its the triceps that give you most of your arm strength. This is no surprise because 65% of your upper body strength is formed of triceps. There are a ton of exercises that use dumbbells to strengthen the triceps. Listed below are just some that are most often recommended.

* Form a very small arc with your back. Then, bend your waist until a right angle is formed (90 degrees). You must then move your upper arm to your back until its in line with the floor. You must straighten your elbow so that your entire arm is perfectly parallel to the floor. To balance, use the other hand to give you support by leaning on a bench or another steady surface.

* You really do not want to perform this exercise on a bench, but on a chair, because the benchs positioning is slightly too high that your aim. Bend your elbow while lifting the dumbbell so that the upper arm is adjacent to your ear. Use the hand that isn't performing the exercise to support the arm that is. Straighten out your elbow so your arms pointing straight into space.

* Make your elbow point up while lying on a flat bench. Use your free hand as support to the back of your upper arm. Then, straighten your elbow so that the arms pointing straight up into the air.
