If you’re looking to build a versatile home gym, learning how to buy adjustable dumbbells is a smart first step. This guide will walk you through everything you need to know to make a great choice.
Adjustable dumbbells save space and money compared to a full rack of fixed weights. They let you change the load quickly for different exercises. But with many models on the market, picking the right set requires some thought.
How To Buy Adjustable Dumbbells
This main section covers the core process. We’ll break down the key factors you should consider before spending any money.
Determine Your Budget Range
Prices for adjustable dumbbells vary wildly. You can spend anywhere from $100 to over $500 for a single set. Setting a clear budget upfront narrows your options.
- Budget-Friendly: Basic dial or pin-select models. They often have lower weight ranges.
- Mid-Range: Most popular selectorized styles (like Bowflex or NordicTrack). They offer good value and features.
- High-End: Commercial-grade or ultra-smooth mechanisms with very high weight limits.
Remember, this is an investment in your health. Sometimes paying a bit more for durability pays off in the long run.
Assess Your Fitness Level and Goals
Are you a beginner, intermediate, or advanced lifter? Your current strength and future goals dictate the weight range you need.
- Beginners: A set that goes from 5 to 50 pounds might be perfect for starting out.
- Strength Training: You’ll need heavier options. Look for sets that go to 90 pounds or more per dumbbell.
- General Fitness: A moderate range (e.g., 10-55 lbs) often suffices for full-body workouts.
Always check the increment between weights. Smaller increments (2.5 lbs) are better for precise progression, especially for beginners.
Understand the Different Types and Mechanisms
How the dumbbells adjust is crucial for convenience and safety. Here are the common types:
Selectorized Dumbbells
You turn a dial or move a selector pin to choose your weight. The change is fast and the design is compact. Brands like Bowflex made these popular. They’re great for circuit training.
Dial-Based Dumbbells
A twist dial on the end of the dumbbell engages the desired weight plates. They function similar to selectorized ones but with a different interface. Just make sure the dial is easy to turn.
Add-On Plate Dumbbells
These use standard weight plates you slide onto a fixed or adjustable-length handle. You secure them with clips or collars. This is often the most cost-effective and expandable option, but changing weight is slower.
PowerBlock or Cage-Style Dumbbells
Weights are arranged in a rectangular block. You insert a selector pin to choose the load. They have a unique feel and are very durable, but some find the shape awkward for certain exercises.
Check Key Features and Specifications
Don’t just look at the price tag. Dig into the details listed on the product page or box.
- Weight Range: The minimum and maximum weight per dumbbell.
- Weight Increments: How much the weight increases with each adjustment.
- Build Quality: Are the materials metal or plastic? How sturdy are the connections?
- Handle Comfort: Look for a secure, knurled grip. It shouldn’t be to slippery or to rough.
- Footprint & Storage: Measure your space. Do they come with a stand? Can they be stored vertically?
- Warranty: A good warranty (2+ years) indicates the company stands behind their product.
Read Reviews and Watch Video Demos
Other users experiences are invaluable. Search for long-term reviews that talk about durability after months of use.
Watch video reviews to see the dumbbells in action. Pay attention to the sound of the mechanism—is it loud or quiet? See how quickly the reviewer can change the weight. This research can reveal flaws or perks not mentioned in the official description.
Consider Where to Buy
You have several options for your purchase. Each has it’s own advantages.
- Direct from Manufacturer: Often the best warranty support, but sales may be limited.
- Major Retailers (Amazon, Walmart, etc.): Convenient shipping, easy returns, and lots of customer reviews in one place.
- Sporting Goods Stores: You can sometimes try them in person before you buy.
- Secondhand Markets (Facebook Marketplace, Craigslist): Potential for big savings, but inspect carefully for damage and ensure all parts are included.
Try Before You Buy (If Possible)
If you have a friend with adjustable dumbbells, ask to try them. Some gyms also have them available. Getting a feel for the handle thickness, balance, and adjustment speed is the best way to know if you’ll like them.
Notice how they feel in your hand during a curl or press. The ergonomics are just as important as the tech specs.
Make Your Purchase and Start Training
Once you’ve done your homework, pull the trigger. When your dumbbells arrive, inspect them immediately for any shipping damage.
Read the manual thoroughly to understand the adjustment mechanism and safety instructions. Start with a weight you can handle comfortably to get used to the feel. Proper form is always more important then lifting heavy right away.
Maintenance and Safety Tips
Take care of your equipment and it will last for years. Here’s how:
- Always store them on a level surface or in their stand.
- Avoid dropping the dumbbells, especially selectorized types, as it can damage the internal mechanism.
- Wipe them down with a dry cloth after use to prevent sweat corrosion.
- Periodically check that all selector pins, dials, or locks are functioning correctly.
- Never use weights that are loose or make unusual noises when shaken.
Frequently Asked Questions (FAQ)
Are adjustable dumbbells worth it?
Yes, for most people. They save a tremendous amount of space and money compared to buying a full set of traditional dumbbells. The convenience encourages more consistent workouts.
What is the best brand of adjustable dumbbell?
There’s no single “best” brand. Popular and reliable brands include Bowflex, PowerBlock, NordicTrack, and Ironmaster. The best one depends on your budget, desired weight range, and preferred adjustment style.
How much should I spend on adjustable dumbbells?
Plan to spend at least $200-$300 for a quality mid-range set from a known brand. Cheaper models often have lower weight limits or less durable construction. View it as a long-term investment.
Can you build muscle with just adjustable dumbbells?
Absolutely. You can perform a huge variety of exercises that target all major muscle groups. As long as you progressively overload (increase weight or reps over time), you can build significant strength and muscle.
What’s the main disadvantage of adjustable dumbbells?
The primary drawback is the slower transition time between exercises compared to grabbing a new fixed dumbbell. Also, some models have a bulky shape that can limit certain movements like goblet squats.
How do adjustable dumbbells work?
They use a mechanical system to lock only the selected weight plates to the handle. When you turn the dial or insert the pin, it engages a specific combination of internal plates, leaving the rest in the stand.
Choosing the right set for your home gym doesn’t have to be confusing. By following these steps—setting a budget, knowing your needs, and researching the types—you’ll find a pair that fits your workouts perfectly. Take your time, and you’ll make a choice you’re happy with for years to come.
