Strengthening the arms is an essential component of a complete fitness regimen. It is not just about aesthetics when it comes to having strong arms. On a functional level, arm strength is required for many of life's everyday actions, such as carrying, lifting, pushing, and pulling.

Here is a breakdown of the muscles you should focus on to build strong arms, as well as the best arm workouts by using adjustable dumbbell that will tone each of those muscles.

1. Bicep Curls

Standing with your feet shoulder-width apart and a weight in each hand, take a deep breath. Lifting the weights toward your shoulders should begin with the weights at your thighs, palms facing forward, and elbows glued to your hips. Release to begin; that counts as one rep. Repeat.

2. Bent-Over Triceps Extension

Stand with your feet hip-width apart, a dumbbell in each hand, and your arms hanging at your sides, do this exercise. The palms of your hands should be facing in. Hang from your hips and keep your knees slightly bent; lean your torso forward until your body is at a 45-degree angle with the ground. Repeat on the other side. While maintaining the position of your upper arms by your chest and your elbows at your sides, stretch your forearms behind you until they are parallel to the floor, then release them to begin for one repetition. Repeat.

3. Dumbbell Curls with a Twist

Your forearm comes into play because of the twist. Each hand should have an adjustable dumbbell in it, with the palms facing each other, at your side. Make use of your biceps to curl the dumbbells alternately up to your shoulders, rotating your hands so that they face your chest as you elevate the weights. Slowly drop the dumbbells back down to your sides and repeat the process.

4. Straight Bar with a Reverse Curl

Standing at shoulder width with an overhand hold on a barbell, do a squat. Rotate the gym barbell upwards, just using your forearms, until your palms are facing out and the barbell is in line with your shoulders, and then repeat the process. Slowly lower it back to the ground and repeat. It is sometimes overlooked since it works the brachialis, a muscle that is not visible lower down your upper arm yet is necessary for developing larger biceps. 

5. Bar Curl with a Forward Lean

You're strengthening the primary flexor muscle involved in finger strength, which will give you a vice-like grasp for the heavier exercises — as well as a bone-crushing handshake for good measure – after you finish. 

• The first step is to hold the bar in front of your thighs.
• You can do this with an underhand.
• A Shoulder-width grip can help you burn more calories.
• Now, step forward a little, at about a 30-degree angle to your hips.
• Inhale through your mouth and curl the bar until your hands are near your shoulders.
• Squeeze your biceps, then lower yourself slowly and steadily.

Conclusion

It is necessary to do exercises at home that target your biceps and triceps to gain more arm size. Try to train these muscles at least twice or three times a week, and as your strength increases, increase the number of repetitions and sets you to do with each exercise you perform.

In addition to completing focused exercises, it is critical to maintaining a diet that is high in complex carbohydrates, protein, and healthy fats and that contains enough calories to fuel your activities.
