How To Change Bowflex Dumbbells

If you own a set of Bowflex adjustable dumbbells, knowing how to change Bowflex dumbbells is the first step to a great workout. This simple adjustment guide will walk you through the process, ensuring you can switch weights quickly and safely between exercises.

These dumbbells are designed for convenience, saving you space and time. But if you’re new to them, the dial system can seem a bit confusing at first. Don’t worry—it’s much easier than it looks. With a little practice, you’ll be changing weights in seconds, keeping your workout flow smooth and efficient.

Before you start twisting dials, it’s important to understand the basic principle. Bowflex SelectTech dumbbells use a numbered dial system to lock weight plates onto the handle. By turning the dial to a specific number, you engage a unique pin pattern that secures the correct combination of plates inside the housing.

Always make adjustments with the dumbbell placed securely on its stand or a flat, level surface. Never try to change the weight while holding the dumbbell in your hand, as this can damage the internal mechanism.

Step-by-Step Adjustment Instructions

Follow these numbered steps every time to ensure a proper and safe weight change.

Place the dumbbell securely on its dedicated stand. If you don’t have the stand, set it on a firm, level floor surface.
Look at the end of the dumbbell handle. You will see a numbered dial, usually ranging from 1 to 15 or higher, depending on your model.
Grip the dial firmly and turn it clockwise or counterclockwise until your desired weight number aligns with the selector arrow or indicator mark on the dumbbell housing.
Listen for a faint “click” or feel the dial settle into place. This confirms the pin is fully engaged in the correct slot.
Lift the dumbbell straight up and away from the stand or floor. Give it a slight shake or tap to ensure no plates are loose. You should hear and feel a solid, single unit.
If you feel any rattling or shifting, set the dumbbell down, re-check the dial alignment, and lift again. Never use the dumbbell if plates feel loose.

Common Mistakes to Avoid

Even with a simple system, a few common errors can cause problems. Being aware of them will keep your equipment in good shape.

Adjusting While in Hand: This puts stress on the locking pins and can lead to premature wear or failure.
Not Using a Level Surface: If the dumbbell is tilted on a uneven surface, the plates inside may not align correctly, preventing a proper lock.
Forcing the Dial: If the dial won’t turn easily, don’t force it. Check that the dumbbell is sitting flat and that no obstructions are in the way. Forcing it can break the selector pin.
Ignoring Rattles: A rattling sound means the weight is not securely locked. Always investigate and resolve this before lifting.

What to Do If Your Dumbbell Gets Stuck

Sometimes, the dial might feel stuck or the plates won’t release. Here’s what to try.

First, set the dumbbell back on a perfectly flat surface. Jiggle the dial gently back and forth between two numbers to help the pins disengage. You can also try turning the dial to the lowest weight setting and then back to your desired number.

If a specific plate seems stuck, visually inspect the dumbbell for any debris like dust, chalk, or small objects that might have fallen into the mechanism. A can of compressed air can be useful for blowing out any particles.

Safety Checks Before Every Use

Making safety a habit is crucial. Perform these quick checks each time you prepare to workout.

Visual Inspection: Look over the dumbbell for any obvious cracks, damage, or worn parts, especially around the dial and handle connections.
Auditory Check: After selecting your weight and lifting, listen for any unusual sounds. A solid “thud” is good; a “clank” or rattle is not.
Weight Verification: Before a heavy set, do a simple test lift. Does the weight feel correct and balanced? If something feels off, set it down and re-dial.

Taking these few extra seconds can prevent accidents and equipment damage. It’s a simple routine that becomes second nature.

Maintenance Tips for Longevity

Your Bowflex dumbbells are an investment. Proper care will keep them working smoothly for years to come.

Keep them in a dry environment to prevent rust on the internal plates. Wipe them down with a dry cloth after use to remove sweat and moisture. Avoid dropping them, as a hard impact can misalign the internal mechanism and plates, even if the exterior looks fine.

Every few months, you might want to lightly wipe the dial area with a clean, dry toothbrush to dislodge any accumulated dust or grime that could interfere with the selector pin’s movement.

Understanding Different Bowflex Models

While the core dial system is similar, there are slight variations between popular models like the SelectTech 552, 1090, and the newer Blaze models.

The SelectTech 552s adjust in 2.5 lb increments up to 25 lbs, and then 5 lb increments up to 52.5 lbs. The 1090 model goes from 10 to 90 lbs. The dial and number system works the same, but the weight increments and maximums differ. Always refer to your specific model’s manual for it’s exact weight chart.

The fundamental process of how to change them, however, remains consistent across the board: dial, click, lift, and check.

Creating an Efficient Workout Flow

Now that you can change weights effortlessly, you can design better workouts. Plan your exercise order to minimize weight changes. For example, do all your heavy chest presses first, then lower the weight for your flyes, rather than alternating back and forth.

If you’re doing circuit training, consider having two sets of adjustable dumbbells if possible, or be strategic about your station order to allow time for adjustments without rushing. Knowing your equipment well makes your time in your home gym much more productive and enjoyable.

Frequently Asked Questions (FAQ)

Here are answers to some common questions about adjusting Bowflex weights.

Why won’t my Bowflex dumbbell dial turn?

This is usually because the dumbbell isn’t sitting flat. Ensure it’s on a level stand or floor. Also, check that no weight plates are partially engaged and blocking the dial’s rotation.

Can I change the weight in the middle of an exercise?

No. You should always set the dumbbell down on a stable surface before attempting to turn the dial. Changing weight while holding it is unsafe and can damage the internal selector pin.

My dumbbell makes a clicking noise when I lift it. Is that normal?

A single, solid click or clunk when you first lift is usually normal—it’s the sound of the handle engaging with the plates. However, a continuous rattle or shaking during the lift is not normal and means the weight is not locked properly.

How do I find the weight chart for my model?

The easiest way is to check the user manual that came with your dumbbells. You can also find this information online by searching for your specific model number, which is usually printed on the dumbbell stand or the dumbbell itself.

What’s the best surface to adjust them on?

The dedicated Bowflex stand is ideal. If you don’t have the stand, use a firm, level floor. Avoid soft surfaces like carpet where the dumbbell can sink in and tilt, as this prevents proper plate alignment.

Mastering your equipment is key to a successful fitness journey. With this guide, you now have the knowledge to adjust your Bowflex dumbbells quickly, safely, and with confidence. Remember the core steps: place, dial, click, lift, and check. Incorporate the maintenance tips, and your dumbbells will provide a reliable workout for countless sessions to come. Now, go put that knowledge to use in your next workout.
