The two most popular adjustable dumbbells take very different approaches. Here's how they compare.

1. Design Differences
Bowflex SelectTech dumbbells use a dial on each end to select weight while the bell sits in its tray, and they look like traditional dumbbells. PowerBlock uses a block-shaped design with a selector pin, which is more compact and often more durable but looks and feels different.
2. Comparison
| Factor | Bowflex SelectTech 552 | PowerBlock Elite (EXP) |
|---|---|---|
| Weight range | 5 - 52.5 lb per hand | 5 - 50 lb, expandable with kits |
| Selection | Dial | Pin selector |
| Shape | Long, traditional | Short, block |
| Durability | Avoid drops; plastic parts | Steel construction, more robust |
| Expandability | Fixed (separate larger model) | Add-on kits for heavier weights |
| Feel | Familiar dumbbell feel | Compact; good for presses |
3. Which Should You Buy?
- Bowflex if you want a classic dumbbell feel and quick dial changes
- PowerBlock if you want durability, a compact shape and room to expand
- Either is a huge space saver compared with a full rack
4. Speed of Weight Changes
Bowflex SelectTech dials are fast: turn both ends and lift the dumbbell from the tray. PowerBlock uses a selector pin that you move to the desired weight, which is also quick once you're used to it. Both are fast enough for supersets and circuits. Bowflex can be a little faster for frequent changes, while PowerBlock feels more robust.
5. Which Is Better for Different Exercises?
Bowflex's longer shape can feel awkward on exercises where the dumbbells come close to the body, such as curls and lateral raises. PowerBlock's compact block shape works well for presses and rows but feels different from traditional dumbbells. Try both if possible, or watch videos of people using them for your favorite exercises.
6. Stands and Storage
Both brands offer stands that hold the dumbbells at waist height, saving your back. Consider the stand cost and footprint when comparing.
7. Our Verdict
Choose Bowflex for classic feel and PowerBlock for durability and expansion.
8. Price Comparison
Both brands sell at similar price points for comparable weight ranges, though PowerBlock expansion kits add cost over time if you upgrade. Bowflex offers models with higher maximum weights as separate purchases. Compare the total cost to reach the weight range you'll eventually need.
9. Warranty and Durability
PowerBlock dumbbells use a steel construction that tolerates more rough use, while Bowflex mechanisms include plastic parts that can crack if dropped. Check warranty terms for both.
10. Final Tip
Buy a stand with either brand. Lifting adjustable dumbbells from waist height protects your back and makes changing weights quicker.
Final Thoughts
Bowflex SelectTech offers a traditional feel with fast dial changes; PowerBlock offers a sturdier, compact and expandable design. Choose based on feel, durability needs and whether you'll want heavier weights later. Product lineups, prices and subscriptions change often. Specs and prices here are typical at the time of writing; check each brand's current models before buying.
