Building muscle with dumbbells is an effective way to increase strength and take your workouts up a notch. Whether you’re a beginner or a seasoned fitness enthusiast, dumbbells can be used to perform a variety of exercises that target all the major muscle groups in the body, including your arms.

There are many different exercises you can do using only dumbbells to help strengthen and tone your arms. For starters, it’s important to remember that form is key and you should always maintain proper posture throughout each exercise. Additionally, the amount of weight you lift varies depending on your current fitness level and goals; begin with light weights until you feel comfortable enough to increase the weight as necessary.

Now, let’s take a look at some of the best dumbbell arm exercises for building muscle.

Hammer Curls

Hammer curls are a great dumbbell exercise to help tone and strengthen the biceps. This exercise can be done with both arms at the same time or one arm at a time.

To do single-arm hammer curls, start by standing with your feet shoulder-width apart and knees slightly bent. Hold a dumbbell in each hand and extend your arms down by your side, with palms facing each other. Keep your upper body steady and exhale as you curl the right dumbbell up and in towards your right shoulder. Squeeze the bicep muscle at the top of the movement before inhaling as you return to starting position. Repeat the same motion on your left arm while maintaining the correct form throughout. Aim for 3 – 5 sets of 10 – 15 repetitions on each arm for maximum results.

Wrist Curls

Wrist curls are a great exercise for building strength and stability in your forearms. This exercise can be done using both dumbbells and barbells.

To begin, sit on a bench with your arms at a 90-degree angle to the floor, palms facing up. Grasp the weights in each hand with an overhand grip. With your wrists slightly bent forward, slowly curl both weights up toward your body and back down again for 15-20 repetitions. Remember to keep your arms firmly planted against the bench throughout the exercise, focusing on the movement of only your wrists as you lift and lower the weights.

Wrist curls help to strengthen the forearm extensors as well as target specific forearm muscles such as flexors and brachialis.

Tricep Extensions

Triceps extensions are a useful exercise for targeting the triceps muscles in your upper arms. The exercise is usually performed with dumbbells and is suitable for all levels of strength training.

The movement involves extending your arms outwards as you curl upwards one at a time, squeezing your triceps at the top of each extension. Keep your hips and back straight and your legs shoulder-width apart to ensure proper form throughout the movement. Start with lighter sets and increase weight as necessary to challenge yourself further.

Tricep extensions can be performed while standing or seated, depending on what’s best for the individual athlete. For beginners, you may want to perform this exercise while seated in order to focus more on proper form, but experienced athletes may find standing best for them. Begin by holding two dumbbells out directly in front of you at shoulder height with an overhand grip (palms facing away). Engage your core as you slowly extend both arms upwards towards the ceiling as far as possible without compromising form, squeeze the triceps at the top of each extension then slowly lower back down again to starting position. Complete 8-12 reps for 3-4 sets depending on ability, making sure that good form takes precedence over all else.


Kickbacks are a great exercise for the triceps muscles and are often part of a balanced triceps routine. They can be done with either dumbbells or cable machines, and the resistance can be adjusted depending on your fitness level.

Kickbacks involve raising one arm behind the body while keeping your elbows close to your torso as if you were making a backward wave. Start in a half-kneeling position with one knee down and one foot flat on the ground. Keeping your head straight, torso upright, and elbow tucked in close to your side, extend your arm backward and hold at the end of the movement for 1-2 seconds before gradually returning to starting position.

You should feel the tension in the back of your upper arm during the pushback motion; if you’re not feeling any tension, you may need to increase resistance or use a higher weight. To do so, start leaner then add weight as needed until you find an appropriate challenge. As always with strength training exercises, proper form is key – don’t overdo it and risk injury!

For best results perform 8-12 repetitions on each arm moving slowly and using good control while focusing on the target muscles being worked.

Bent-Over Raises

Bent-over raises are an excellent, targeted exercise that uses dumbbells to help build and define the musculature of the shoulders. This exercise helps to target both the anterior and medial deltoids, giving you a balanced, strong look in your arms.

To perform a bent-over raise, take a pair of dumbbells and rest them on your thighs or sit on an upright bench with back support. Bend forward from your hips until you are at about a 45-degree angle with your torso parallel to the floor and arms extended close to your body. Keep your head up and your eyes focused ahead. Squeezing the shoulder blades together, lift the weights forward until they are in line with your shoulders level before slowly returning them to starting position. Make sure you keep your back straight throughout this movement for maximum benefit as well as to avoid injury. While holding the weights, do not hold your breath or hyper-extend during this exercise – both can lead to injury!

Perform 10 – 12 reps in three sets if you’re just starting out building shoulder strength; increase reps or weight over time depending on how quickly you progress in strength building. To really make progress and build stronger muscles more quickly each session, consider incorporating three different types of bent-over raises into each workout such as alternating front raises, side lateral raises, and bent-over lateral raises for maximum effect!


In general, the idea is that if you focus on quality reps and form, controlling the weight as you lift and lower it as well as keeping your form strict while doing big compound lifts like presses and rows, you’ll get more results. Additionally, make sure to include some accessory work like drop sets or cable machines for variety.
Finally, don’t neglect nutrition – it’s essential for success in any fitness journey!
