If you own a set of Bowflex adjustable dumbbells, knowing how to adjust Bowflex dumbbells is the first step to a great workout. This guide will walk you through the process for different models, troubleshoot common issues, and help you get the most from your equipment.
How To Adjust Bowflex Dumbbells
The adjustment mechanism is what makes these dumbbells so convenient. While the core idea is the same, the exact steps can vary between series. Let’s break it down by the most popular models.
Adjusting the Bowflex SelectTech 552 & 1090 Dumbbells
These are the classic dial-a-weight models. The process is very straightforward.
- Place the dumbbell on a flat, level surface. This is crucial for the dial to turn smoothly.
- Turn the selection dial clockwise until it clicks into your desired weight setting. The numbers on the dial align with the weight markings on the dumbbell.
- Lift the dumbbell straight up. You will hear and feel the unused weight plates disengage and stay in the tray.
- To return it, lower the dumbbell straight down into the tray. The dial will click as it settles.
- Turn the dial back to the lowest setting before storing or adjusting again.
Adjusting the Bowflex SelectTech 840 & Stand
The 840 model uses a similar dial system but often comes with a specific stand. The adjustment steps are identical to the 552 model. The stand simply makes picking up and placing down the dumbbells easier and protects your floor.
Important Safety Note for All Dial Models
Always ensure the dial is clicked firmly into a number, not between settings. A misaligned dial can cause plates to fall loose during your lift, which is a safety hazard. Also, never try to change the weight while the dumbbell is in the air.
Adjusting Older Bowflex Models (Like the PowerPro)
Older styles, such as the PowerPro, use a pin system instead of a dial. Here’s how you adjust them:
- Set the dumbbell on a stable surface.
- Locate the selector pin attached to the handle by a cord.
- Insert the pin into the hole corresponding to the weight you want. You’ll usually see the weight numbers marked along the side.
- Pull the pin out firmly to return the dumbbell to it’s starting position after your set.
Common Problems and Troubleshooting
Even the best gear can have hiccups. Here are solutions to frequent issues.
Dumbbell Won’t Adjust or Dial is Stuck
If the dial won’t turn, don’t force it. First, check for obstructions like dust or small debris in the dial mechanism. A can of compressed air can help blow it out. Sometimes, placing the dumbbell perfectly level in it’s tray is all it needs to free up.
Weight Plates Are Loose or Rattle
A slight sound is normal, but excessive rattling often means the dumbbell isn’t fully engaged. Lower it back into the tray and lift it straight up again. If the problem persists, inspect for worn plastic tabs on the plates—these might need replacement from Bowflex customer service.
Uneven Weight Selection
You pick up the dumbbell and one side feels heavier. This almost always means the dials on the two dumbbells are set to different weights. Double-check that both are clicked into the same number. It’s an easy mistake to make when your in a hurry between sets.
Maintenance Tips for Longevity
Taking good care of your dumbbells ensures they last for years and perform reliably.
- Store them in the included tray or stand on a level floor. Avoid leaving them on carpet where the dial can get misaligned.
- Keep them clean. Wipe down the handles with a dry cloth after use to prevent sweat corrosion. A lightly damp cloth can clean the body, but avoid harsh chemicals.
- Never drop the dumbbells. Even though they feel sturdy, the internal mechanism can be damaged from impact.
- Periodically check for wear. Look at the dial, the plastic housing, and the connection points. Catching a small issue early prevents bigger problems.
Getting the Most From Your Workouts
Easy adjustment means more efficient training. Here’s how to leverage that.
Supersets and Drop Sets Made Simple
The quick change system is perfect for advanced techniques. For a drop set, perform an exercise to fatigue, then immediately lower the weight by turning the dial and continuing your set. You can do this without hardly any rest, increasing workout intensity.
Organizing Your Home Gym Space
Keep your workout area clear around the dumbbell tray. This gives you safe space to adjust weights and prevents you from tripping over other equipment when your handling the dumbbells. Good organization makes your routine smoother.
Weight Increment Recommendations
Bowflex dumbbells increase in small increments (usually 2.5 or 5 lbs). A good rule is to increase weight when you can complete all your planned sets and reps with perfect form. The next increment up should challenge you on the final few reps.
Frequently Asked Questions (FAQ)
Why won’t my Bowflex dumbbell dial turn?
The most common reason is the dumbbell isn’t sitting flat in it’s tray. Remove it, clear any debris, and place it back evenly. Forcing the dial can break it.
Can I use one dumbbell without the other?
Yes, each dumbbell works independently. This is useful for unilateral exercises like single-arm rows or shoulder presses.
Are Bowflex dumbbells safe to drop?
No. They are not designed like traditional rubber-coated hex dumbbells. Dropping them can damage the internal selector mechanism and void the warranty.
How do I find the model number of my Bowflex dumbbells?
The model number (e.g., 552, 1090) is usually printed on a label on the side of the dumbbell tray or directly on the dumbbell housing. Knowing this helps when you need to order parts.
My weights feel off—is the calibration wrong?
It’s very unlikely the weight is miscalibrated. First, check for dirt in the mechanism causing drag. If one specific plate feels stuck, it may not be fully disengaging. Contact customer support if you suspect a true mechanical fault.
Mastering how to adjust your Bowflex dumbbells is simple once you know the steps for your specific model. Regular care and proper use will keep them functioning perfectly, making your home workouts both effective and efficient. Remember to always prioritize safety by checking the dial or pin before each lift.
