BowFlex Results Series SelectTech Dumbbells

This pick is ideal for users who prioritize rapid weight changes, thanks to its dial-based adjustment mechanism. It replaces multiple dumbbells with a single space-efficient set, with weights ranging from 5 to 52.5 pounds. The robust metal components and ergonomic handles make workouts comfortable and secure. The main tradeoff is the weight limit, which may not suffice for advanced lifters, and the need for space to store the included trays. Compared to more versatile sets, BowFlex offers unmatched convenience for dynamic routines.
Pros:
- Space-saving design replaces multiple weights
- Quick adjustment dials for easy changes
- Durable metal construction with secure locking
- Ergonomic, non-slip handles for comfort
Cons:
- Limited maximum weight of 52.5 pounds

Key Differences
The Bowflex SelectTech 552 emphasizes smooth, dial-based weight adjustments that feel seamless during workouts, making them ideal for users who value ease and speed of change. Their larger size may require more space but offers a familiar dumbbell shape. In contrast, PowerBlock Elite features a compact, rectangular design with a toggle mechanism that enables quick weight changes, suitable for those with limited space or who prefer a more durable, metal build. The choice hinges on whether you prioritize ease of use and traditional feel or durability and space efficiency.Detailed Comparison
Adjustment mechanism (Bowflex SelectTech 552 wins — moderate)
The Bowflex uses a dial system that increments weight smoothly, which is very user-friendly and minimizes errors. PowerBlock employs a toggle system, which allows rapid switching but may require a slight learning curve. The gap is moderate; for beginners or those who want simplicity, Bowflex wins. For quick, frequent adjustments, PowerBlock is advantageous.Maximum weight per dumbbell (PowerBlock Elite wins — major)
The Bowflex reaches 52.5 lbs per hand, sufficient for many strength routines. PowerBlock can be expanded up to 70 lbs with additional kits, offering more versatility for heavier lifting. The difference is significant for advanced users needing heavier weights; for casual or beginner users, Bowflex’s limit is usually enough.Physical size and storage (PowerBlock Elite wins — moderate)
Bowflex dumbbells are larger and resemble traditional dumbbells, which may require more storage space. PowerBlock’s compact rectangular design is easier to stow away in tight spaces. For small home gyms, PowerBlock’s size is a clear advantage. For those with ample space, size is less critical.Ease of use (Bowflex SelectTech 552 wins — moderate)
The Bowflex’s dial is intuitive once understood, providing gradual weight increments. PowerBlock’s toggle is quick but slightly less intuitive initially, especially for new users. Overall, Bowflex wins for ease, especially for beginners or those who prefer traditional feel.Durability and build quality (PowerBlock Elite wins — moderate)
PowerBlock’s all-metal construction offers high durability and longevity, especially under frequent use. Bowflex’s plastic components are sturdy but slightly more prone to wear over time. For high-use environments, PowerBlock is more dependable; for casual use, Bowflex’s quality suffices.Price (Bowflex SelectTech 552 wins — moderate)
Bowflex SelectTech 552 is generally more affordable, making it attractive for budget-conscious buyers. PowerBlock Elite’s higher price reflects its build quality and expandability. Users valuing multi-purpose, long-term durability may find the extra cost justified.Comfort and ergonomics (Bowflex SelectTech 552 wins — minor)
Both options have ergonomic handles, but Bowflex’s traditional shape offers a familiar grip. PowerBlock’s rectangular design may feel bulkier but remains comfortable with padded handles. Comfort is subjective; both are suitable for extended use.Expandability (PowerBlock Elite wins — moderate)
PowerBlock offers expandability with additional weight kits, making it suitable for progression. Bowflex’s design is fixed, so upgrading isn’t an option. For users planning long-term strength gains, PowerBlock provides more flexibility.Bowflex SelectTech 552: Pros and Cons
