If you own a set of Bowflex SelectTech dumbbells, knowing how to change weight on Bowflex dumbbells is the first skill you need to master. These adjustable dumbbells are fantastic for saving space, but the mechanism can be confusing the first time you use them. This guide will walk you through the simple process, cover common issues, and give you tips to keep your equipment working smoothly for years.
How to Change Weight on Bowflex Dumbbells
The core process for adjusting Bowflex SelectTech dumbbells is straightforward once you understand it. The system uses a dial-and-tray mechanism to securely lock the selected weight plates in place. Here’s the basic method that applies to most models like the 552, 1090, and the newer 840.
Step-by-Step Adjustment Guide
Follow these numbered steps every time to adjust your dumbbells safely and correctly.
- Place the Dumbbell on a Flat, Level Surface. Always adjust them on the floor or a sturdy bench. Never try to change the weight while holding them in the air.
- Turn the Dial to Align with Your Desired Weight. Rotate the dial on each end until the number for the weight you want clicks into the indicator window. Make sure both ends are set to the same number.
- Lift the Dumbbell Straight Up. Grasp the handle firmly and lift it vertically out of the cradle. You should hear a slight click as the weight plates lock onto the handle.
- You’re Ready to Exercise. The selected weight is now securely attached. Perform your workout as usual.
- To Lower the Weight, Return it Carefully. After your set, place the dumbbell back into the cradle straight down. Do not drop it. Once it’s resting in the tray, you can turn the dials to a new setting.
Crucial Safety Tips During Adjustment
Safety should always be your top priority. Ignoring these tips can lead to damage or injury.
- Always double-check that both dials are on the same weight number. A mismatch can cause the dumbbell to be unbalanced and unsafe.
- Lift the dumbbell straight up and lower it straight down. Angled or sideways force can jam the mechanism or cause plates to fall off.
- Never, ever try to change the dial setting while the dumbbell is lifted out of the cradle. The adjustment must only happen when it is fully resting in the tray.
- Keep the area around the dumbbells clear. Make sure no obstructions like other weights or towels are in the cradle when you try to lift.
Identifying Your Bowflex Dumbbell Model
The adjustment process is similar across models, but knowing your specific one helps with troubleshooting. You can usually find the model number on a label on the cradle or the dumbbell itself.
- SelectTech 552: Adjusts from 5 to 52.5 pounds in 2.5-pound increments. This is the most common model.
- SelectTech 1090: Adjusts from 10 to 90 pounds. It’s larger and uses a similar dial system.
- SelectTech 840: An older model with a slightly different visual design but the same fundamental operation.
What If the Plates Feel Loose or Don’t Lock?
If you lift the dumbbell and hear a rattling sound or feel the plates are loose, something is wrong. Immediately set it back down gently. The most common cause is that the dials are not fully turned to a click-stop position. Ensure the number is perfectly centered in the indicator window. Also, check for any small debris like pebbles or gym chalk blocking the plates from seating properly.
Troubleshooting Common Problems
Even with great care, you might encounter issues over time. Here are solutions to the most frequent problems people face.
Dumbbell is Stuck or Won’t Lift Out
This is frustrating but often easy to fix. First, don’t force it. Forcing can break the plastic dials or internal parts.
- Check for a weight mismatch between the two dials. Correct them so they match.
- Ensure the dumbbell is sitting completely flat in its cradle. Rock it gently to seat it properly.
- Inspect the dials for damage. If a dial is cracked or broken, it may not be engaging the locking mechanism inside.
Weights Don’t Change When Dial is Turned
If you turn the dial but the plates don’t seem to disengage or change, there could be internal issue. Try lifting the dumbbell and giving it a gentle shake (over the cradle) to see if any loose plates fall off. If the problem persists, the internal selector may be worn or a spring could be broken. This might require contacting Bowflex customer support.
Cleaning and Maintenance for Smooth Operation
A little maintenance prevents most problems. About once a month, take a few minutes to care for your equipment.
- Wipe down the dumbbells and cradle with a dry cloth to remove dust and sweat.
- Use a can of compressed air to blow out any debris from the weight plate slots and the dial area.
- You can apply a very small amount of silicone-based lubricant on the metal rails inside the cradle if things feel sticky. Avoid oil-based lubricants that attract dirt.
Maximizing Your Workout with Adjustable Dumbbells
The real benefit of knowing how to change weight quickly is for your workouts. You can move between exercises with minimal rest.
Creating Efficient Supersets and Circuits
Since you can change weight in seconds, you can design workouts that keep your heart rate up. For example, you can do a set of heavy chest presses, then immediately lower the weight for a set of tricep extensions without moving to a new station. This saves time and increases workout intensity.
Progressing and Overloading Effectively
The small increments (like 2.5 pounds on the 552 model) are perfect for progressive overload. When an exercise gets to easy, you don’t have to jump a huge 10-pound increase. You can simply add the next smallest increment, which is safer and more sustainable for building strength over time. Make sure you record the weights you use so you know when to move up.
Frequently Asked Questions (FAQ)
Here are quick answers to some of the most common questions about Bowflex adjustable dumbbells.
Can you change the weight on Bowflex dumbbells while they’re in the air?
No, you must never do this. The dumbbell must be fully resting in its cradle to turn the dials safely. Changing weight in the air is dangerous and will damage the internal mechanism.
Why won’t my Bowflex dumbbells dial turn?
First, make sure the dumbbell is in the cradle. If it still won’t turn, look for visible obstructions or damage. Sometimes, if a weight plate is slightly misaligned, it can block the dial. Gently lifting and re-seating the dumbbell can help.
Are Bowflex dumbbells hard to adjust?
Not at all once you get the hang of it. The process—dial, lift, exercise, return, re-dial—becomes second nature after a few workouts. The key is patience and following the steps exactly as designed.
What do I do if a weight plate falls off?
If a plate detaches, carefully set the dumbbell down. Check the dial setting and the plate slots for debris. Usually, re-seating the dumbbell in the cradle and ensuring the dial is clicked to a valid number will solve it. If plates repeatedly fall off, the lock mechanism may need service.
How do you change the weight on older Bowflex models?
Most older Bowflex SelectTech models use the same dial system. The instructions above apply. If you have a very old model with a different mechanism, refer to the original user manual or look for a model-specific video online for guidance.
Mastering your Bowflex adjustable dumbbells opens up a full home gym experience. By following these clear steps for adjustment, performing regular simple maintenance, and using them safely, you’ll get years of effective workouts without any hassle. Remember, the consistent, correct use is what leads to great results.
