Are you struggling to pack on muscle? Have you got access to dumbbells? If you answered yes to both, then keep reading! Because today, I will be sharing a hardgainer dumbbell workout to build muscle!

Hardgainers can build muscle using dumbbells by performing a programme of compound and isolation-type exercises which target all the muscles in the body. This training should also be combined with regular progressive overload, a caloric surplus, and a high protein diet.

I use to be a self-proclaimed “hardgainer” myself, so I know your struggles.

But I also managed to gain 40lbs of lean muscle. And I want to share some of the exercises which helped me to do so.

So let’s jump right in!

I used to be a hardgainer but gained 40lbs of lean muscle with the help of these dumbbell exercises
Dumbbell exercises helped me transform my body as a hardgainer. Read to the end for a free blueprint of how I did it!

12 Hardgainer Dumbbell Exercises For A Workout

First, here are 12 dumbbell exercises which should be included in every hardgainer’s dumbbell training programme:

1. Dumbbell Bench Press.

How To Dumbbell Bench Press & Improve Chest Activation

What I Say:

You can perform the bench press with a barbell or dumbbell. But the dumbbell bench press is perfect for hardgainers to get a good pump on the pectorals.

In support of this, a 2016 study showed that the dumbbell bench press led to 4% higher pectoral activation, compared to the barbell bench press.

Bar chart showing bench dumbbell bench press activates pectorals more than barbell bench press

I recommend using a weight which allows you to perform 8 reps per set, for 3 or 4 sets. And progressively overload each week by increasing rep number.

Once you reach 12 reps per set (the threshold before hypertrophy training turns into endurance training), begin to increase weight instead of reps.

What The Expert Says:

Mike Deward (CSCS Coach at Barbend) notes that the the dumbbell bench press is “extremely effective” at increasing pec, tricep, and deltoid strength and mass.

He also explains that the greater range of motion in a dumbbell bench press leads to a greater stretch, compared to a barbell bench press. And this increases blood flow to the pecs, which is beneficial for muscle growth.

What You Need:

  • Dumbbells.
  • Flat weight bench.

The dumbbell bench press is an effective dumbbell exercise for increasing strength and mass in the pectoral, anterior deltoids, and tricep muscles. The greater range of motion provided by dumbbells leads to a greater muscle stretch, compared to the barbell bench press. And this is beneficial for muscular hypertrophy.

2. Dumbbell Chest Fly.

The ONLY Way You Should Be Doing A Dumbbell Fly!

What I Say:

The dumbbell chest fly is an awesome dumbbell exercise to isolate the pecs. This can be extremely useful for hardgainers who have yet to master the bench press technique.

When you perform the bench press with sub-par technique, you often unintentionally push with your triceps and anterior deltoids.

As a result, you don’t engage the pecs properly.

Instead, hardgainers can perform dumbbell chest flyes to exclusively work the pecs, whilst working on your bench pressing technique.

What The Experts Say:

Andrew Heffernan (CSCS Coach at Openfit) notes that the chest fly is a great exercise to stretch your pectoral muscle fibres (and thus promoting muscle growth).

He also recommends performing chest flyes to at END of your chest workout (for example, after your dumbbell bench presses). That way, you can ensure your pecs are worked to their absolute limit.

What You Need:

  • Dumbbells.
  • Flat weight bench.

The dumbbell chest fly is a great exercise to isolate a contraction directly onto your pectoral muscles. This exercise can be combined with the bench press to ensure the chest muscles receive maximal stimulation. And this will ensure growth in the pectoral muscle.

3. Standing Dumbbell Shoulder Press.

How to: Standing DB Shoulder Press for Physique Development

What I Say:

This is a dumbbell exercise I highly recommend hardgainers to perform, and it’s one I wish I did more of in my early lifting days.

The dumbbell shoulder press will mainly help you develop broader shoulders as a hardgainer. More specifically, it activates the anterior, posterior, and lateral deltoids as the primary mover.

But being a compound exercise, it also works the triceps and to some extent, the upper pecs.

As a result, the dumbbell shoulder press helps hardgainers to develop overall upper body pushing strength. And this also benefits other exercises such as the dumbbell bench press.

What The Experts Say:

Tom Kelso (Coach at Breaking Muscle) points us to a 2013 study to show the effectiveness of the dumbbell shoulder press.

This study demonstrated that performing the standing overhead press using dumbbells resulted in a 15% greater anterior deltoid activation, and 7% greater lateral deltoid activation, compared to the barbell overhead press.

bar chart showing dumbbell shoulder press activates deltoids more than barbell shoulder press

What You Need:

  • Dumbbells-only.

The standing dumbbell overhead press is an effective dumbbell exercise to develop broader shoulders. It primarily activates the anterior, lateral, and posterior deltoids. But also engages the triceps and upper pecs to stabilise the movement. This increases upper body pushing power, which also benefits exercises such as the bench press.

4. Dumbbell Lateral Raise.

How To Perform The Dumbbell Lateral Raise For Bigger Shoulders

What I Say:

The shoulders are one of the more difficult upper body muscle groups to develop. This makes deltoid isolation exercises perfect for hardgainers to grow broader shoulders.

The lateral raise is a deltoid isolation exercise which primarily activates the anterior, lateral, and posterior deltoids. Although the trapezius is also activated as a stabiliser.

This is an effective exercise for hardgainers to target the lateral deltoids in particular, which are difficult to isolate otherwise.

Though effective, this exercise is hard!

So start with a light weight and focus on overloading with more weight or reps, slowly (but steadily) each week.

What The Experts Say:

Mike Dewar at Barbend explains the lateral raise is the perfect dumbbell exercise to focus your training directly onto the shoulders.

He explains that strength deficiencies in smaller muscle groups such as the deltoids can often be hidden by the larger neighbouring muscles like the upper pecs.

Furthermore, these deficiencies will also limit your capabilities to grow bigger shoulders.

By performing the lateral raise, you can specifically target the deltoids for growth.

What You Need:

  • Dumbbells-only.

The dumbbell lateral raise is an important accessory exercise to develop bigger shoulders. It will specifically engage the anterior, lateral, and posterior deltoids. Strength deficiencies in these smaller muscles are often hidden by larger, neighbouring muscles. This makes it important to isolate the deltoids with the lateral raise.

5. Dumbbell Overhead Tricep Extension.

Dumbbell Overhead Triceps Tips

What I Say:

The triceps comprise almost two thirds of the upper arm muscle mass. And this makes it important for hardgainers who want larger arms, to find exercises which work the triceps.

Many of the other upper body pushing exercises (such as the bench press and overhead press) also engage the triceps as secondary movers.

But if you want to specifically engage the triceps, you should perform dumbbell tricep-isolation exercises such as the overhead tricep extension.

What The Experts Say:

Josh and Kyle from Colossus Fitness explains that many people incorrectly perform the overhead tricep extension, flaring their elbows outwards.

If you do this, you are not isolating the tension onto the triceps. And as a result, your triceps will not gain significant imporvements in size and definition.

Instead, Josh and Kyle reccomend you to tuck the elbows towards to head. And this will maximise tricep engagement.

What You Need:

  • Dumbbells-only.

The overhead dumbbell tricep extension is a isolation-type exercise which can be used to specifically work the triceps. To ensure tension is localised directly onto the triceps, you should keep your elbows tucked towards the head, instead of flaring them outwards.

6. Dumbbell Bicep Curl.

Bicep Curls — (DUMBBELL FORM & TECHNIQUE)

What I Say:

The bicep curl is an excellent complementary exercise to pair with the tricep extension.

Together, they will hit ALL the muscles in your upper arm.

I would advise you to perform them at the END of your dumbbell workout though.

That’s because many of the other dumbbell compound pulling exercises (such as the row and the pull-up) also engage the biceps as a secondary mover.

You should work your biceps to fatigue. But not at the expense of compromising your compound pulling exercises (which are big muscle-builders).

What The Experts Say:

Anthony Yeung (CSCS Coach at Mens Journal) recommends you to include a variety of dumbbell curls:

  • Classic underhand-grip curl.
  • Reverse-grip curl.
  • Hammer curl.
  • Concentration curl.

By varying the grip, you will target the different muscles in the biceps (including the biceps brachii, brachialis, and brachioradialis).

What You Need:

  • Dumbbells-only.

The dumbbell curl is an effective exercise which targets the biceps. To gain maximum benefits from dumbbells curls you should include variations such as the reverse-grip, hammer-grip, and concentration-grip. By altering the grip and workout angle, you will engage the biceps brachii, brachiallis, and brachioradialis.

7. Bent-Over Dumbbell Row.

Standing Dumbbell Row

What I Say:

This is one of my favourite compound pulling exercises, and I highly recommend you to include them in your hardgainer training programme.

The dumbbell bent-over row is a powerful exercise which will hit all the muscles in your back, as well as the biceps.

By altering your grip-width, you will ensure all the individual muscles in the back are engaged.

I recommend you to switch your grip every 2 weeks. For example, use a narrow overhand grip in your first two weeks. Then switch to a wide-overhand grip in the following two weeks.

Doing so will keep introduce variety in your training. And this is a great way for hardgainers to build a killer back!

What The Experts Say:

Stuart Carter (Personal Trainer at Fit Father Project) notes that the dumbbell bent-over row is a great exercise for building a thicker back, rather than a wider back.

That’s because the dumbbell bent-over row emphasises contraction in the trapezius and rhomboids, which are located in the middle of the back.

What You Need:

  • Dumbbells-only.

The dumbbell bent-over row is a compound pulling exercise which activates the trapezius, rhomboids, latissimus dorsi, and biceps. It is a great exercise to develop a thicker back. To maximise back muscle hypertrophy, you should change your grip on a biweekly basis to introduce variety.

8. Dumbbell-Weighted Pull-Up.

Weighted (Dumbbell) Pull ups - Learn the Exact Form

What I Say:

The pull-up can often be neglected by hardgainers. Mainly because it’s so hard to do!

But trust me, you should practice until you are able to complete bodyweight pull-up repetitions.

And when you are able to do 3 sets of 10 bodyweight pull-ups, you can can hold a 5lb dumbbell between your legs and decrease the reps as necessary.

The dumbbell-weighted pull up is the best exercise to develop your latissimus dorsi (lats), as well as your other back muscles.

And by the time you start adding weights to your pull up, you will find your back to have developed a wide flare!

What The Experts Say:

Liam Rodgers (Fitness Writer and Weightlifter at Pullup Mate) explains that adding a dumbbell to your pull up will provide a greater mechanical tension to your back muscles.

When you do this, the new stimulus will encourage your muscles to grow in strength and size!

What You Need:

  • Dumbbells.
  • Pull up bar.

The dumbbell-weighted-pull up is a powerful compound pulling exercise which engages the trapezius, rhomboids, latissimus dorsi, and biceps. Developing the latissimus dorsi in particular, will result in a wider back.

9. Dumbbell Crunch.

The BEST Dumbbell Exercises - ABS EDITION!

What I Say:

There can be a limited range of abdominal exercises if you don’t have access to cable machines.

But the dumbbell crunch is a great dumbbell exercise to add mass and definition to your abs.

You can perform the traditional crunch to target the mid-abs. Or you can include a twisting motion at the end to engage the obliques, which are found to the side fo the abdominals.

Either way, by holding a dumbbell whilst performing the exercise, you will provide the resistance required to stimulate muscle growth in the abs!

What The Experts Say:

Jim Stoppani PhD (Health and Nutrition Consultant at Jim Stoppani) recommends holding the dumbbell directly over the head, with your arms fully extended. Then contract your abs to lift your shoulders off the ground. Doing this will directly target the abdominal muscles!

What You Need:

  • Dumbbells-only.

The dumbbell crunch is a great way to add mass and definition to your abdominals. The traditional crunch engages the mid abdominals, but you can also hold a dumbbell above the head whilst performing the crunch. This will provide the mechanical tension required to stimulate muscle growth.

10. Dumbbell Leg Raise.

How To: Leg-Lift Version 1

What I Say:

The lower abdominals are notoriously hard to develop, especially for hardgainers!

I recommend performing dumbbell leg raises to directly target the lower abs.

You will want to start by using your body weight first. And once you have mastered this, you can hold a 5lb dumbbell between your legs as you perform the leg raise.

Tip: it’s much easier to do this on a power tower than hanging off a pull up bar!

What The Experts Say:

Jeff Cavaliere (CSCS Coach at Athlean-X) adivises you to flex the spine at the pelvis, and to raise the feet to head level, before lowering them. This is the best way to engage the lower abdominals (rather than the hip flexors).

What You Need:

  • Dumbbells.
  • Power tower.

The leg raise is an isolation-type exercise which is great for targeting the lower abdominals. By adding a dumbbell to the exercise, you create a greater mechanical tension required to drive muscle growth. You can also incorporate a twist as you raise your legs, and this emphasises the external obliques.

11. Dumbbell Lunge.

How To: Dumbbell Stepping Lunge

What I Say:

The dumbbell lunge is an awesome compound leg exercise which engages all the muscles in the leg. But particular emphasis is placed on the quadriceps and hamstrings.

I would recommend hardgainers to include intense leg workouts in your training programme.

Not only will you see balanced upper/lower body development, but this 2014 study shows a weight training-induced hormonal response. And this response correlates with muscle size.

In other words, the bigger the muscle, the bigger the muscle-building hormone release.

And the leg muscles are some of the largest in your body!

What The Experts Say:

Mike Dewar at Barbend notes the unilateral (one-sided) nature of the lunge is a great way to correct muscle imbalances in the leg, and this will improve leg strength in bilateral exercises such as the squat.

He also recommends the lunge to be a great exercise to develop muscle size in the legs!

What You Need:

  • Dumbbells-only.

The dumbbell lunge is a great unilateral exercise to increase muscle size and strength in the lower body. The lunge movement is also a compound exercise which will engage all the muscles in the leg, including the quadriceps, hamstrings, gluteus maximus, and gastrocnemius.

12. Goblet Squat.

What I Say:

All hardgainers should concentrate on leg-work to develop overall body musculature. This is because of the muscle-building hormone response described above.

The goblet squat is one of the major dumbbell exercises you can perform to target the legs.

I would recommend you to tuck your elbows into your body as you hold the dumbbell. This reduces the amount of fatigue in your arms and shoulders as you perform the squat.

As a result, you will be able to work your legs harder!

What The Experts Say:

Avi Silverberg (Powerlifter Coach at Powerlifting Technique) advises you to perform the goblet squat in a slow and controlled manner.

That’s because a goblet squat is often limited by the weight of the dumbbell (which usually has a maximum capacity of around 110lbs).

So to ensure a high intensity (despite a limited weight), perform the movement slowly.

What You Need:

  • Dumbbells-only.

The goblet squat is a a dumbbell-variation of the barbell squat, a compound exercise which engages the quadriceps, hamstrings, gluteus maximus, and gastrocnemius. The goblet squat should be performed with the elbows tucked into the body to reduce fatigue in the arms.

Example Full-Body Hardgainer Dumbbell Workout.

Now, I will put the 12 exercises together.

Here is an example of a full-body hardgainer dumbbell workout:

Dumbbell ExerciseSetsRepsWeightRest Between Sets
Bench Press Or Chest Fly3970% Of 1RM2 Min
Lunge Or Goblet Squat3975% Of 1RM.2 Min
Bodyweight/Dumbbell-Weighted Pull Up Or Dumbbell Row3975% Of 1RM2 Min
Shoulder Press Or Lateral Raise3975% Of 1RM2 Min
Bicep Curls Or Tricep Extension3975% Of 1RM2 Min
Weighted Crunch Or Leg Raise3975% Of 1RM2 Min

This workout will take around 1 hour to complete.

For each workout, choose 1 exercise from each section. Then on the next week, you should perform the exercise you didn’t perform the previous week.

If you are a hardgainer who has just begun lifting weights then aim to complete 3 workouts a week. But ideally, you should progress to 4, then 5, workouts per week (when you feel ready to do so).

Notes:

  • Follow the exercise order- it has been designed to allow similar muscle groups to recover before being hit again.
  • Vary your angles- for the bench press and fly. For example, if you perform a flat bench press one week, then do an incline bench press the next. If you do an incline chest fly one week, then do a flat chest fly the next.
  • Overload when ready- by increasing weight, decreasing rest times to 1 min, and increasing number of training days. But focus on one area to overload at a time.
  • Perform dumbbell-weighted pull ups after you have mastered bodyweight pull ups- after being able to perform around 10 repetitions of bodyweight pull ups, you can add a dumbbell.
  • Choose either bicep curls or tricep extension per workout- the other compound exercises will hit your biceps and triceps already.
  • 1RM = 1 rep max

If you don’t know what 1 rep max is, read my other article on ideal lifting weight!
