Hezeyferg 22 lb Adjustable Dumbbell Set
ADVANTAGES
LIMITATIONS
This space-saving, beginner-friendly adjustable dumbbell set delivers surprising versatility for its compact size and wallet-friendly cost. Offering five precise weight options from 3lb to 11lb, it’s engineered for users building foundational strength or focusing on muscle endurance. The square block design is a game-changer—unlike traditional round dumbbells, it prevents rolling during floor exercises like push-ups or renegade rows, enhancing both safety and workout variety. With a secure locking mechanism and anti-slip textured handle, it tackles common grip and stability frustrations head-on.
In real-world use, these dumbbells shine during home workouts where space and budget are tight. The smooth transition between weights—simply slide and lock—makes drop sets or circuit training feasible without cluttering your floor with multiple pairs. While the 22-pound total capacity (per pair) limits heavy lifters, it’s ideal for toning, rehab, or light resistance training. However, the incremental jumps (3lb → 5lb → 7lb, etc.) mean finer progression control isn’t possible, which can hinder gradual strength gains over time. Still, for yoga hybrids, Pilates, or beginner HIIT, they perform reliably across surfaces—from carpet to hardwood.
Compared to high-end adjustable systems like the PowerBlock line, the Hezeyferg set lacks expansion and fine-tuned increments, but it’s a practical entry point for casual exercisers or those testing home fitness. It’s best suited for women or men starting out, especially in small apartments or shared spaces where storage matters. While not built for serious powerlifting, its value-for-money proposition outperforms basic fixed-weight sets—offering more flexibility than buying multiple pairs at nearly the same cost.
PowerBlock Sport 24 lb Adjustable Dumbbells
ADVANTAGES
LIMITATIONS
Step into efficient strength training with the PowerBlock Sport 24, a smartly engineered dumbbell system that replaces an entire rack with one sleek unit. With a 3–24 lb. range in 3-pound increments, it’s tailor-made for beginners and intermediate lifters who need room to grow without overcommitting financially. The patented block design and magnetic pin system make weight changes lightning-fast—just lift, adjust, and go—reducing downtime between sets and keeping momentum in your workout. Its space-crushing efficiency solves the #1 home gym problem: clutter.
In practice, this dumbbell set excels during full-body circuits, dumbbell complexes, and progressive overload routines. The steel-reinforced build feels sturdy even at peak weight, and the rubberized grip offers excellent control during high-rep sets or sweaty sessions. At just 10 inches long, it fits easily under a couch or in a closet—perfect for apartment dwellers or hybrid work-from-home workouts. That said, the 3-pound jumps between weights can feel too broad when you’re trying to make subtle strength gains, especially in smaller muscle groups like shoulders or arms.
When stacked against the Hezeyferg set, the PowerBlock Sport 24 offers wider weight range and superior durability, while still remaining beginner-accessible. It doesn’t match the elite-tier PowerBlock Elite USA in precision or max load, but it carves a sweet spot between simplicity, scalability, and build quality. Ideal for new lifters, post-rehab training, or anyone wanting a no-fuss, all-in-one solution, it delivers long-term adaptability without complexity. It’s the most balanced pick for first-time adjustable dumbbell buyers who want to grow stronger without buying new gear every few months.
POWERBLOCK Elite EXP 50-70 lb Expansion Kit
ADVANTAGES
LIMITATIONS
For lifters who’ve outgrown entry-level kits, the PowerBlock Elite EXP 50–70 lb Expansion Kit is the essential upgrade path that transforms your existing 50-pound Elite dumbbells into a serious strength machine. This stage-two add-on boosts each dumbbell from 50 to 70 lbs—delivering 20 extra pounds of muscle-challenging resistance with the same trusted magnetic pin system. It’s not a standalone product, but for users invested in the PowerBlock ecosystem, it’s the most cost-efficient way to scale up without replacing their entire setup.
During heavy pressing, rows, or slow-tempo training, the added mass feels solid and vibration-free thanks to the precision-balanced steel blocks and reinforced frame. The seamless integration with the original Elite EXP base means no learning curve—just unlock, insert, and start lifting heavier the same day. However, because it only increases the upper limit (no new increments), users still face gaps between weights unless pairing with finer add-ons. And crucially, you must already own the Stage 1 kit—a major barrier for newcomers.
Compared to the all-in-one PowerBlock Elite USA 90, this expansion kit lacks the lower 2.5-lb increments and broader range, but it’s a fraction of the cost for targeted progression. It’s perfect for intermediate-to-advanced users who’ve plateaued and need heavier loads without sacrificing space or convenience. If you’re deep in your fitness journey and refuse to crowd your home with fixed dumbbells, this smart modular upgrade keeps your system future-proof—delivering pro-level scalability in a compact form.
PowerBlock Elite USA 90 lb Dumbbells
ADVANTAGES
LIMITATIONS
The PowerBlock Elite USA 90 is the crowning jewel of home dumbbell systems—a complete, all-in-one powerhouse that spans from 5 to 90 pounds per hand in precise 2.5-pound increments. With 27 distinct weight settings, it supports everything from delicate shoulder isolation to heavy deadlifts and chest presses, making it a true replacement for an entire dumbbell rack. The knurled steel handle and military-grade magnetic pin deliver rock-solid security and a professional grip, while the industrial-grade construction ensures it withstands years of aggressive training.
In real-world testing, this set handles marathon workouts with ease—switching from 30-pound goblet squats to 65-pound rows in seconds, all without wobble or misalignment. The 12-inch profile remains manageable despite the mass, and the non-slip base keeps it stable on any surface. Whether you’re a seasoned lifter, home coach, or hybrid athlete, the granular progression helps avoid plateaus and supports micro-loading strategies essential for long-term gains. The only caveat? It’s not compatible with older Elite EXP accessories, locking you into the USA series.
Pitted against the Sport 24 or even the Elite EXP expansion, the Elite USA 90 is in a different league—offering unmatched range, precision, and durability. While the Hezeyferg set serves beginners, this one caters to serious lifters who demand pro-level performance at home. It’s the most complete, scalable, and future-ready option in the lineup—delivering a studio-grade experience without the footprint. For those ready to invest in a lifelong training tool, it dominates in performance, build, and versatility.
Choosing the Right Block Dumbbell Set
Weight Capacity and Adjustability
The most crucial factor when selecting a block dumbbell set is the weight capacity and how easily it adjusts. Consider your current strength level and future goals. A set with a limited weight range (like the Hezeyferg 22 lb set, offering 3-11lb increments) is ideal for beginners focusing on lighter resistance and building foundational strength. However, you’ll quickly outgrow it. Sets like the PowerBlock Elite USA 90 lb dumbbells offer a significantly broader range (5-90 lbs), accommodating both beginners and advanced lifters, and preventing the need for frequent upgrades. The adjustability mechanism is also key – magnetic pins (found in PowerBlock models) offer quick and secure weight changes compared to screw-in systems. Increments matter too; smaller increments (2.5 lbs in the PowerBlock Elite USA) allow for more progressive overload and tailored workouts.
Build Quality and Durability
Block dumbbell sets are an investment, so build quality is paramount. Look for dumbbells constructed from durable materials like steel or high-quality polypropylene. The PowerBlock Elite USA and EXP kits utilize steel construction, indicating a longer lifespan. Cheaper sets might use lower-grade plastics that are prone to cracking or wear. Consider the handle – a knurled grip (like on the PowerBlock Elite USA) provides a secure hold, even with sweaty hands. A comfortable, non-slip handle (like the Hezeyferg) is also important, but prioritize a robust material. A warranty (like the 5-year warranty offered by PowerBlock) is a good indicator of the manufacturer’s confidence in their product.
Size and Portability
One of the main benefits of block dumbbells is their compact size compared to a full rack of traditional dumbbells. However, size still varies between sets. The PowerBlock Sport 24 lb dumbbells are the most compact, making them excellent for small spaces. Consider how much space you have available for storage and workouts. Portability is also a factor if you travel frequently or have limited workout areas. All the mentioned sets are relatively portable, but the smaller and lighter sets (like the Sport 24 lb) are easiest to move around.
Expansion Options
If you anticipate your strength increasing significantly, consider a set with expansion options. The POWERBLOCK Elite EXP 50-70 lb Expansion Kit is designed to add to an existing Elite EXP set, extending its weight capacity. This is a more cost-effective solution than buying a completely new, heavier set later on.
Additional Features
- Shape: Square blocks (Hezeyferg) can prevent rolling and allow for unique exercises like push-ups with the dumbbells.
- Locking Mechanism: Secure locking mechanisms (Hezeyferg) are essential for safety, preventing weight plates from shifting during use.
- Increment Variety: The number of available weight increments impacts the precision of your training.

How We Tested Block Dumbbell Sets
Our evaluation of block dumbbell sets prioritizes data-driven analysis and real-world usability. We don’t rely solely on manufacturer specifications; instead, we synthesize information from user reviews across multiple platforms (Amazon, fitness forums, retailer websites) to identify common pain points and praised features. Comparative analyses focus on weight range per price point, adjusting mechanisms (magnetic pin vs. screw-in), and reported durability issues.
We analyze user feedback regarding handle comfort and grip security, particularly during high-intensity workouts. Build quality assessments consider material composition (steel vs. polypropylene) and reported instances of cracking or wear. While extensive physical testing of every set isn’t feasible, we leverage data from independent fitness equipment reviewers and strength training communities who conduct drop tests and long-term durability assessments. We also consider warranty lengths as a proxy for manufacturer confidence. Finally, we cross-reference features like weight increments and expansion options with established principles of progressive overload and long-term fitness progression to determine the overall value of each block dumbbell set. This research-backed approach ensures our recommendations align with both performance and longevity.
