Whether you’re looking at Powerblock dumbbells, the iconic Bowflex SelectTech, or the cult-favorite Ironmaster dumbbells, we’ll help you find your perfect match.
What to Consider Before You Buy
Your ideal dumbbell depends on your priorities. Ask yourself these questions:
- Feel: Do you need the traditional, round head feel of a pro-grade dumbbell, or is a unique shape okay?
- Speed: How important is a near-instant weight change to your workout flow?
- Durability: Are you a gentle user or do you plan on dropping them from overhead?
- Budget: Are you looking for a budget-friendly entry point or a “buy it for life” investment?
- Expansion: Do you see yourself needing heavier weights down the line?
The Top Contenders: A Detailed Breakdown
Here’s how the most popular adjustable dumbbells stack up against each other.
1. Powerblock Elite USA
- The Gist: The rugged, expandable, and incredibly popular choice for serious lifters.
- Mechanism: Uses a series of selector rods that slide into the block to add weight plates. Weight is changed by moving the selector pin.
- Pros:
- Highly Durable: Built to withstand serious use and are often rated for drops.
- Easily Expandable: Most Powerblock models can be expanded with add-on kits (e.g., from 50lb to 70lb to 90lb) without buying a whole new set.
- Excellent Warranty: A standout 5-year warranty on the urethane-coated Elite USA series.
- Space-Saving: The vertical design has a very small footprint.
- Cons:
- Unique Feel: The square shape and wide handles take some getting used to for certain exercises like goblet squats.
- Slower Changes: Weight changes are slightly slower than a dial mechanism.
- Best For: The lifter who values durability, expandability, and a commercial-grade build above all else. Ideal for garage gyms.
2. Bowflex SelectTech 552
- The Gist: The mainstream king of rapid weight changes and sleek design.
- Mechanism: The famous dial system. Turn the dial to your desired weight, lift, and the internal mechanism locks the correct plates in place.
- Pros:
- Blazing Fast Changes: The fastest weight change on the market. Perfect for high-intensity interval training (HIIT).
- User-Friendly: The dial system is intuitive and easy for anyone to use.
- Sleek Aesthetics: They look modern and clean sitting in a room.
- Cons:
- Durability Concerns: The internal plastic components are a known failure point, especially if treated roughly. The warranty has become more limited.
- Not Expandable: You are locked into the weight range you buy (usually 52.5lbs or 90lbs per dumbbell).
- Bulky Design: They have a large horizontal footprint when not in use.
- Best For: The casual to intermediate lifter who prioritizes speed and convenience and treats their equipment with care.
3. Ironmaster Quick-Lock
- The Gist: The indestructible, “buy it for life” tank of adjustable dumbbells.
- Mechanism: Uses a patented quick-lock lever to secure traditional iron plates to a handle. This is the least “gadgety” feel of the bunch.
- Pros:
- Unmatched Durability: Made of solid steel. These are virtually indestructible and feel exactly like gym dumbbells.
- Incredible Feel: The compact, round heads and knurled metal handles provide the most authentic dumbbell experience.
- Fully Expandable: You can buy additional plates to take them as heavy as you want.
- Cons:
- Slowest Changes: Changing weight requires manually adding or removing plates with the locking lever. It’s a deliberate process.
- Price: Among the most expensive options upfront.
- Weight: They are extremely heavy, even at lower weights.
- Best For: The purest and the strength athlete who wants a permanent, professional-grade set and doesn’t mind a slower pace.
4. Nuobell
- The Gist: The best feeling and most innovative mechanism on the market, but at a premium price.
- Mechanism: A beautiful dial-free mechanism that uses a series of sliding locks. The dumbbell adjusts seamlessly and retains a perfectly cylindrical shape at every weight.
- Pros:
- Perfect Feel: They look, feel, and balance exactly like a traditional hex dumbbell. No compromise.
- Very Fast Changes: Almost as fast as Bowflex, but with a much more satisfying and durable mechanism.
- Quiet Operation: The adjustment is smooth and quiet.
- Cons:
- Price: The most expensive option by a significant margin.
- Durability Unknown: As a newer player, their long-term durability isn’t as proven as Ironmaster or Powerblock.
- Weight Limit: Currently maxes out at 80lbs per dumbbell.
- Best For: The enthusiast who wants the ultimate combination of feel, speed, and aesthetics and has the budget to match.
