How To Adjust Powerblock Dumbbells

If you own a set of PowerBlock dumbbells, you know they’re a space-saving game-changer. But if you’re not sure how to adjust PowerBlock dumbbells, you might be missing out on their full potential. This guide will walk you through the simple process, making your workouts smoother and more efficient.

Adjustable dumbbells like PowerBlocks replace an entire rack of weights. They work by adding or removing steel plates inside the selector cage. Mastering the adjustment is key to a fast and safe training session.

Let’s get your weights set up correctly.

The core adjustment method is similar across most PowerBlock models. You’ll use a selector pin to choose your weight. The pin goes through holes in the weight plates inside the handle cage.

Always make sure you adjust both dumbbells to the same weight before starting your set. An imbalance can lead to injury.

Step-by-Step Adjustment Guide

Follow these steps every time you need to change the load.

Step 1: Place the Dumbbell on a Flat, Stable Surface

Never try to adjust them while your holding them in the air. Set them down on the floor or their stand. This prevents accidental drops and gives you a clear view of the selector pins.

A stable surface is crucial for safety.

Step 2: Identify the Selector Pin and Weight Numbers

Look at the end of the handle. You’ll see a colored pin with a knob or handle. Next to it, numbers are printed on the cage indicating the weight in pounds or kilograms.

Familiarize yourself with this layout before you start pulling pins.

Step 3: Pull the Selector Pin Straight Out

Grip the pin’s handle firmly. Pull it straight out until it stops. You don’t need to force it; it should slide out smoothly.

If it’s stuck, jiggle it gently while pulling. Never yank it at an angle.

Step 4: Align the Pin with Your Desired Weight Number

While the pin is out, look at the weight numbers. Move the pin so it lines up directly with the hole next to the weight you want.

For example, if you want 25 pounds, line the pin up with the “25” marker.

Step 5: Push the Selector Pin Fully Back In

Once aligned, push the pin firmly back into the hole. You should hear or feel a click as it locks into place. Give the pin a gentle tug to confirm it’s secure.

A pin that isn’t fully seated can come out during exercise.

Step 6: Repeat for the Second Dumbbell

Always adjust both dumbbells. Double-check that the weight on both is identical. This ensures balanced strength development.

Now you’re ready to lift.

Adding Expansion Kits (For Pro, Sport, and Elite Models)

Many PowerBlocks are expandable. This lets you increase their maximum weight. The process involves adding extra weight plates to the ends.

First, you must purchase the correct expansion kit for your specific model and series.

Remove all selector pins from the dumbbell.
Slide the existing weight stack out of the handle cage (if required by your model).
Place the new expansion plates onto the guide rods or into the cage.
Re-insert the original weight stack on top of the expansion plates.
Replace the selector pin. The new, higher weight numbers will now be active.

Always refer to the official manual for your exact model. The steps can vary slightly.

Switching Between Exercises Quickly

The beauty of adjustable dumbbells is speed. To supercharge your workout flow:

Plan your workout circuit in advance. Know your weight for each exercise.
Adjust both dumbbells immediately after finishing a set, before your rest period is over.
Keep the dumbbells on their stand. This makes access and adjustment faster than if they’re on the floor.

With a little practice, you can change weight in under 10 seconds.

Common Troubleshooting Tips

Sometimes, you might encounter a minor issue. Here’s how to fix common problems.

Selector Pin is Stuck or Hard to Pull

This can happen if the dumbbells are new or if dust gets inside. Don’t use excessive force.

Try wiggling the pin gently side-to-side while pulling.
Check that the weight plates inside are not misaligned. Give the whole dumbbell a light shake.
Use a dry silicone spray on the pin. Avoid oily lubricants that attract more dirt.

Weight Feels Loose or Rattles

A rattling sound means the internal weights aren’t locked tight.

Ensure the selector pin is pushed ALL the way in until it clicks.
Check that you are using the dumbbell on a level surface. Some models can slightly unlock if tilted during adjustment.
Inspect for worn or damaged selector pins. Contact PowerBlock customer service for replacements if needed.

Numbers are Worn Off or Hard to Read

With heavy use, the printed numbers can fade.

Use a permanent marker or a label maker to re-mark the weight numbers.
You can also memorize the pin position. For instance, “second hole from the top” for a specific weight.

Safety Checks Before Every Workout

A quick safety inspection takes seconds but is vital.

Verify both selector pins are fully inserted and locked.
Lift the dumbbell a few inches and shake it gently. Listen for any unusual rattles.
Check the handle and welds for any signs of damage or cracks.
Always use the included stand or place them securely on the floor where they won’t be tripped over.

Taking these precautions prevents accidents and protects your equipment.

Cleaning and Maintaining Your PowerBlocks

Good maintenance keeps the adjustment mechanism smooth.

Wipe down the handles and cage with a dry cloth after each use to remove sweat.
Every few months, use a dry brush or compressed air to dust out the weight plate areas.
If the selector pins become stiff, apply a small amount of dry lubricant as mentioned earlier.
Avoid storing them in damp garages or basements to prevent rust.

Simple care makes them last for years and years.

FAQ: Your PowerBlock Adjustment Questions Answered

Can I drop my PowerBlock dumbbells?

It is not recommended. While they are sturdy, dropping them can damage the internal mechanism, bend the selector pins, or crack the outer cage. Always set them down controllably.

Why won’t my PowerBlock pin go in all the way?

The most common reason is that the internal weight plates are not perfectly aligned. Set the dumbbell down flat, remove the pin, and gently shake the whole unit. Then try re-inserting the pin.

Are all PowerBlock adjustment systems the same?

The basic pin-and-selector system is consistent, but the handle design, pin style, and expansion method differ between series like the Sport, Elite, and Pro. Always check your owner’s manual.

How do I know which expansion kit to buy?

The kit must match your exact model name and series. This information is on the original label on the dumbbell or its stand. You can also find it on your purchase receipt or by contacting PowerBlock with the serial number.

My dumbbell is stuck at one weight. What should I do?

First, try the alignment shake. If that fails, inspect for a bent selector pin or an obstructions inside the weight channel. If you see visible damage, stop using them and seek professional repair.

Is it normal for them to make a slight sound?

A faint clicking or shifting sound when you move them can be normal due to the free-moving plates inside the cage. However, a loud rattle or clunk usually indicates a pin isn’t fully locked.

Adjusting your PowerBlock dumbbells should be quick and simple. Once you get the hang of the selector pin system, you’ll spend less time fumbling and more time lifting. Remember the golden rules: always adjust on a flat surface, always check the pin is locked, and always match the weights in your pair.

With this guide, you can confidently use your equipment to its fullest. Proper adjustment is the first step toward a safer and more effective strength training routine.
