Build seriously strong arms with this effective arm workout with dumbbells. A combination of isolated strength training exercises and short power burnouts sculpt and strengthen every muscle in the upper body. All you need is a set of dumbbells to target the back, biceps, chest, triceps and shoulders!
I love leg day, but there’s something about a heavy arm workout that just makes me feel so strong and confident.
Many people are focused on the aesthetic of toned arms, but a strong upper body is also incredibly functional. Every time you push open a heavy door, lift a baby or carry a bag, you’re relying on your back and arm muscles. Increasing your upper body strength can also support better posture and balance, leading to fewer falls and injuries.
Today’s arm workout with weights is a complete upper body strength session, with circuits hitting the biceps, triceps, back, shoulders and chest.
You don’t need an expensive gym membership or fancy equipment to sculpt and tone your arms. In fact, I’ve found efficient home workouts to be more effective than my long gym sessions for building upper body muscle!
Compared to gym machines (such as a cable machine or a lat pull-down machine), dumbbells engage more of the smaller, stabilizing muscles in the upper body. Using free weights (such as dumbbells or kettlebells) also allows you to train in multiple planes of motion, mimicking real-life movement patterns.
Workout Details
This dumbbell arm workout is designed to build strength and muscle definition in the upper body, without a barbell or fancy gym equipment. Modifications are offered throughout, making this suitable for any fitness level. If you’re pregnant, follow along with modifications or substitute my Pregnancy Arm Workout or Prenatal Push Workout.
I recommend incorporating 1-2 at-home arm workouts into your weekly workout plan, spaced out with lower body workouts, full body workouts and rest days.
Workout Equipment
Medium to Heavy Set of Dumbbells. I recommend between 5-25 lbs, depending on your fitness level. I’m using 15-25 lb dumbbells in today’s workout.
Lifting weights is essential for achieving muscle growth and burning body fat (which results in that toned look). If your goal is to improve definition in your arms, reach for heavier weights.
I recommend finding a weight that allows you to perform 8-10 reps of each exercise without dropping to lighter weights. The final 2-3 reps should be challenging, but allow you to maintain proper form.
4 Circuits (2 strength exercises and 1 power exercise per circuit)
Reps and Timed Intervals (8-10 reps of each strength exercise and 30 seconds of work for each power exercise. Perform as many repetitions as you can in the timed interval.)
Repeat Each Circuit x2 Sets (only performing the power move x1)
Note: I re-filmed this dumbbell arms workout to improve video and sound quality (and changed up some of the moves). You can find the original workout video here.
Targets: All 3 heads of the deltoids, also known as your shoulder muscles.
How To Do A Shoulder Overhead Press
Stand tall, feet shoulder-width apart. Hold a dumbbell in each hand.
Keep a slight bend in your knees, engage your core and squeeze your glutes (to protect your lower back) as you ‘goalpost’ your arms by turning the palms out so they’re facing away from your face; elbows parallel to shoulders.
Then exhale as you perform an overhead shoulder press, pushing the weights up, locking out your elbows (biceps by ears), arms straight overhead.
Slowly lower the weights back down to shoulder height, returning to the starting position.
2. Lateral Shoulder Raise
Targets: The lateral deltoid (also engages the anterior deltoid and posterior deltoid).
How To Do A Lateral Raise
Stand with your feet shoulder-width apart, with a slight bend in your knees. Hold a dumbbell in each hand at hip level, palms are facing in towards each other.
Engage your core as you lift the dumbbells out to the sides, keeping a slight bend in each elbow. Lift the dumbbells just to shoulder height.
Slowly lower the dumbbells to the starting position.
3. Single Arm Back Row
Targets: Latissimus dorsi (or lats; the largest back muscle known for its large, flat “V” shape), rear delts (back part of shoulder muscles) and core.
How To Do A Single Arm Back Row
Stand with your feet slightly wider than shoulder-width apart, knees slightly bent. Option to keep feet parallel or take a staggered stance to better support your low back (stepping your left leg slightly behind your right leg).
Hold a dumbbell in your left hand, palm facing in (narrow grip).
Bend forward at the hips, maintaining a flat back, belly button pulled back towards your spine.
Pull the dumbbell back towards your left hip (think of pulling from your elbow joint versus your wrist), as if you were starting a pull-start lawnmower. Stop once your elbow is in line with your rib cage, making a straight line from shoulder to elbow. Hold the row at the top for a moment squeezing your shoulder blade in.
With control, lower the dumbbell back to the starting position and repeat.
4. Back Fly
Targets: The posterior deltoids (rear shoulders) and major upper back muscles, including the rhomboids and trapezius.
How To Do A Back Fly
Stand with your feet slightly wider than shoulder-width apart, knees slightly bent. Grip a pair of dumbbells, palms facing in towards each other. Hinge forward at the hips.
Open your arms and squeeze your shoulder blades together as you raise the dumbbells. Aim to bring dumbbells just to shoulder height. Range of motion will look slightly different for everyone.
With control, slowly lower the dumbbells back down, returning to starting position.
5. Bicep Curl
Targets: Biceps (the front of the arm), specifically the biceps brachii, brachialis and brachioradialis.
How To Do A Bicep Curl
Start standing with feet hip-width apart and core engaged. Hold a dumbbell in each hand at your sides, palms facing outward (underhand grip or supine curl).
Keeping your elbows locked by your sides, squeeze your bicep muscle to curl the weights up to shoulder height.
At the top of the movement, rotate your hands so palms face in towards each other (hammer curl). With control, slowly lower the dumbbells down to your sides.
At the bottom of your movement, flip your grip so palms face out again. Return to the starting position and repeat this movement.
6. Overhead Tricep Extension
Targets: The triceps (back of the arm). This move also engages all the stabilizing muscles in the shoulders, core, glutes and lower back muscles.
How To Do A Overhead Tricep Extension
Start standing with feet shoulder-width apart, back straight, core engaged and knees slightly bent. Hold one dumbbell vertically between your palms overhead.
Slowly bend your elbows to a 90-degree angle, bringing the dumbbell behind your head. Think ‘hide the dumbbell, show the dumbbell,’ if you were watching yourself in a mirror. Keep your elbows close to your ears throughout the entire movement (don’t let your elbows flare out as you fatigue).
Squeeze through the back of your arm as you exhale, pressing the dumbbell overhead, arms fully extended.
7. Dumbbell Chest Press
Targets: Pectoral muscles (chest) and both the anterior and lateral heads of the deltoid (upper arms and shoulders).
How To Do A Chest Press
Lie flat on your back (on the ground, bench or incline bench) with knees slightly bent and feet flat on the floor. Hold one dumbbell in each hand (palms facing knees), elbows bent at a 90-degree angle.
Exhale as you push both dumbbells overhead at the same time; dumbbells stacked over your shoulders at the top of the press. Make sure your wrists are strong and in line with your shoulders.
Lower the dumbbells back towards your chest with control.
8. Chest Fly
Targets: Chest muscles, both the larger pectoralis major and the smaller pectoralis minor.
How To Do A Chest Fly
Lay flat on your back (on the ground, on a bench, or on a stability ball) with one dumbbell in each hand, arms extended above your shoulders, palms facing in towards each other. Press your feet firmly into the floor.
Inhale as you slowly open your arms, lowering the dumbbells in a wide arc until they reach shoulder level (or the ground). Your elbows should remain soft and not over-extended (slight bend in the elbows).
Exhale and squeeze your chest muscles together as you pull the dumbbells back to the starting position. Keep your chest puffed out and your elbows slightly bent.
9. Push Up to Side Plank
Targets: Every muscle in the upper body (chest, shoulders, triceps, back and biceps), obliques, core and transverse abdominis.
How To Do A Push Up to T
Start in a high plank position with your shoulders stacked over your wrists; feet hip-width apart.
Hold this plank position, maintaining a straight line with your body, gaze slightly in front of you.
Slowly lower your chest down towards the ground as your elbows fall back towards your hips.
Once at the bottom of your push-up, exhale as you push back up into a high plank position, performing one push-up.
Then, rotate your body into a side plank position, turning to one side so your weight shifts onto your forearm, which should be directly under your shoulder. Extend your right leg straight out and place the inside edge of your foot on the mat, while your bottom leg hovers just beneath it, fully off the floor.
Hold for three seconds, then return to a high plank position with your shoulders stacked over your wrists; feet hip-width apart.
Modification: If you can’t do a full push-up on your toes, you can substitute one of these push-up modifications. If push-ups hurt your wrists, substitute one of these exercises for wrist pain.

FAQs
What are the best dumbbell arm exercises?
The best dumbbell arm exercises target all the major muscle groups in your arms: biceps, triceps and shoulders. Five of the most effective dumbbell arm exercises are bicep curls, tricep extensions, shoulder presses, chest presses and back rows. When combined, these exercises target every muscle in the upper body.
Can a set of dumbbells replace the gym for upper-body exercises?
You don’t need fancy gym equipment to build strong arms — there are plenty of upper body workouts you can do at home with just a set of dumbbells. Exercises like bicep curls, back rows, shoulder presses and tricep kickbacks are incredibly effective at building strong arms at home.
Can you build muscle with bodyweight training?
While lifting weights is the most effective way to build muscle, bodyweight arm exercises like planks and push-ups can be effective, too. Resistance band arm workouts are another way you can tone your arms without weights. A well-rounded workout routine will challenge you in a variety of ways, including cardio, lower-body workouts and upper-body workouts.
Hi Lindsay! Thank you so much for posting these great workout videos! I’ve really enjoyed them…especially the prenatal ones. You’ve been such an inspiration to me throughout this pregnancy…I’ve been able to lift heavier than I was able to pre pregnancy and feel stronger than ever! I’m almost 39 weeks pregnant now and am thinking ahead to the 4th trimester. If you have time, I would really appreciate a post on your latest journey from having a baby to getting back to working out again. I’m interested to navigate this part of having a baby and there’s not a whole lot of information out there for women who have been lifting heavy and have been active right up until the end.
Haley! I’m so glad you’re loving the workouts! I’m so glad you are feeling STRONG and I hope you are proud of all your hard work during pregnancy! Keep up the great work and yes, we have lots of great postnatal content ready for you after baby too! -Lindsey
Needed a good strength workout after being sick and not having a lot of breathe the last few weeks, this was great! Ease back into cardio while getting a hard upper body workout. Thanks Lindsey!
