If you want to build stronger, more defined shoulders, you don’t need a full gym of equipment. With a pair of PowerBlock Pro 100 Adjustable Dumbbells, a PowerBench 2.0, and about 50 minutes, you can complete a challenging shoulder workout that targets every part of the deltoid.

On PowerBlock's YouTube Channel, Coach Josh takes you through a six-movement routine that includes a dynamic warm-up, compound pressing, and several isolation exercises to fully train the shoulders.

The entire session can be completed with adjustable dumbbells, making it an excellent option for home gyms where space is limited but performance still matters.

Equipment Needed

For this workout, you'll need:

• Any of PowerBlock's Adjustable Dumbbells, Coach Jos uses the PowerBlock Pro 100 Adjustable Dumbbells

• PowerBench 2.0 (or another adjustable workout bench)

• Water

• An electrolyte drink (optional but recommended)

One of the biggest advantages of using PowerBlock Adjustable Dumbbells is how quickly you can change weight between exercises, warm-up sets, working sets, and drop sets—without needing an entire rack of dumbbells.

Why Dumbbell Workouts Are So Effective

Adjustable dumbbells are one of the most versatile pieces of strength equipment you can own. Unlike machines that guide your movement, dumbbells require your stabilizing muscles to work harder, helping improve coordination, balance, and overall strength.

Benefits of training with adjustable dumbbells include:

• Training multiple muscle groups at once

• Improving shoulder stability

• Allowing natural movement patterns

• Saving space in your home gym

• Quickly adjusting weight between exercises

With PowerBlock Adjustable Dumbbells, you can move seamlessly between light warm-up sets, heavy presses, and drop sets in seconds, making your workouts more efficient.

1. Butterfly Shoulder Warm-Up

Sets: 2
Reps: 20

Before lifting heavier weights, it's important to prepare your shoulders.

Using the lightest weight available (or just the PowerBlock handles), lean over your bench with your chest just above the pad.

Perform a butterfly-style motion similar to a swimming stroke, bringing your arms overhead before returning to the starting position.

This movement takes your shoulders through their full range of motion while warming up the muscles, tendons, and ligaments before heavier compound lifts.

Rest about 45 seconds between sets while focusing on slow, controlled breathing.

2. Dumbbell Shoulder Press

Warm-up: 3 sets of 5 reps

Working Set: 6–10 reps

The shoulder press is the primary compound movement of this workout.

Instead of placing your bench completely upright, Coach Josh recommends setting it between 60 and 80 degrees, which is often more comfortable and places less stress on the shoulders.

Key Coaching Tips

• Keep your elbows at around 45 degrees from your body.

• Maintain a neutral spine by slightly tucking your chin.

• Press the weights overhead with control.

• Lower the dumbbells slowly back to shoulder height.

Begin with three "feeler" sets, gradually increasing the weight until you find a challenging working weight.

Once you've reached your working weight, perform 6–10 reps with good form.

Finish with a Drop Set

Immediately after your working set:

1. Cut the weight approximately in half.

2. Perform as many quality reps as possible.

3. Aim for roughly double the reps you completed during your working set.

Drop sets help increase training volume and extend time under tension, making them an excellent tool for building muscle.

3. Dumbbell Lateral Raise

Sets: 3

Reps: 10–12

Lateral raises target the side deltoids to help build wider-looking shoulders.

Rather than lifting the dumbbells straight upward, imagine you're pushing two walls away from your body.

Keep the dumbbells slightly in front of your hips while raising them out to your sides.

Coach Josh also recommends imagining you're pouring two pitchers of water at the top of the movement. This cue naturally keeps your elbows above your hands while protecting the shoulder joint.

Use slow, controlled reps and avoid swinging the weight.

4. Single-Arm Rear Delt Fly

Sets: 3

Reps: 10 per arm

Rear delts are often overlooked, but they play an important role in shoulder stability, posture, and balanced muscle development.

Using a bench or another sturdy support, lean forward until your torso is nearly parallel with the floor.

Lead each repetition with your pinky finger while maintaining control throughout the movement.

Because the rear deltoid is a relatively small muscle, focus on quality movement rather than lifting heavier weights.

5. Upright Row

Sets: 2 working sets + drop set

The upright row is an excellent finishing movement because it challenges multiple portions of the shoulder simultaneously.

Hold the dumbbells close to your body and drive your elbows upward while keeping your shoulders relaxed.

Stop around chest height and avoid shrugging your shoulders during the lift.

Alternative Equipment Option

If you own the PowerBlock EZ Curl Bar Attachment, Coach Josh recommends using it for upright rows since the wider grip can feel more comfortable for many lifters.

Finish your final working set with one drop set by cutting the weight approximately in half and performing as many controlled reps as possible.

6. Dumbbell Shrugs

Sets: 2

Reps: 10

Finish the workout by training your trapezius muscles.

Hold the dumbbells at your sides, allowing gravity to gently pull your shoulders downward before shrugging them up and slightly back.

Choose a weight that challenges both your traps and your grip while maintaining good posture throughout every repetition.

Recovery Tips

Your workout doesn't end after your last rep.

Coach Josh recommends:

• Rehydrating with water.

• Replacing electrolytes lost during training.

• Eating a meal containing protein and carbohydrates to help replenish glycogen stores and support muscle recovery.

Proper recovery helps prepare your body for your next workout and supports long-term progress.
