We compared these two current 50-pound-class sets from Bowflex’s official Results Series 552 page and PowerBlock’s official Pro 50 page, both fetched November 10, 2026, with additional context from BarBend’s adjustable-dumbbell roundup updated August 21, 2026. We haven’t used either set ourselves, and we don’t give scores. This is a mid-range head-to-head, not a review of the heavier Results Series 1090 or the expandable Pro 100 EXP; those are the right next step if you already need more than about 50 lb per hand. Confirm the live price, shipping and the exact model name — BarBend notes a June 5, 2025 recall of older Bowflex 552 and 1090 dumbbells, which are not the Results Series replacements sold now.
Choose the Bowflex Results Series 552 SelectTech ($399 sale / $479 regular on Bowflex’s page, plus $30 shipping; 5–52.5 lb, 15 dial settings, trays included) if you want a familiar round-dumbbell shape and a lower current sale price. Choose the PowerBlock Pro 50 ($549, free shipping in the lower 48; 5–50 lb in 2.5 lb steps, 13" × 7" frame, no stand required) if you want finer increments, a smaller footprint and a five-year residential warranty, and you are sure 50 lb per hand is enough. Neither set expands past its ceiling.

What are the pros and cons?
Bowflex Results Series 552 SelectTech: pros
- Lower current sale price: $399 vs $549 on the official pages we fetched (sale listed through November 14, 2026)
- Slightly higher ceiling (52.5 vs 50 lb) and a traditional round-dumbbell shape
- Trays included; BarBend’s beginner pick for a simple dial
Bowflex Results Series 552 SelectTech: cons
- Two-year parts warranty vs PowerBlock’s five-year residential coverage
- BarBend was still testing the Results Series replacement as of August 21, 2026, and cautions against rough cradle use
- $30 shipping on Bowflex’s page; increments jump to 5 lb after 25 lb
PowerBlock Pro 50: pros
- Finer 2.5 lb steps all the way to 50 lb, and a smaller 13" × 7" footprint
- Five-year residential warranty and free shipping in the lower 48, per PowerBlock
- No stand required to change weight; optional Pro Series kettlebell and barbell attachments
PowerBlock Pro 50: cons
- Higher list price at $549, and a hard 50 lb ceiling with no expansion kits
- Block-shaped handle is a different feel from a round dumbbell
- TPR grip is standard; knurled handles are a $179 extra on the Pro Series accessory list
Which should you choose: Bowflex Results Series 552 SelectTech or PowerBlock Pro 50?
If you want the more familiar shape and the lower November 2026 sale price, the Results Series 552 is the practical pick, as long as you treat the trays kindly and accept a two-year parts warranty. If you care more about 2.5 lb jumps, a smaller footprint and a longer residential warranty, and you are confident 50 lb per hand is enough, the Pro 50 is the more compact tool — just know you cannot add stages later. Lifters who already see 50 lb coming soon should skip both and look at the Pro 100 EXP or a 60 lb QuickDraw, which we cover in the adjustable-dumbbell guide. We have not trained with either set, so treat drop and durability comments from BarBend as theirs, not a lab score from us.
Choose Bowflex Results Series 552 SelectTech if…
- You want a traditional dumbbell shape and a simple twist dial
- The $399 sale price (plus $30 shipping) matters more than a five-year warranty
- 52.5 lb is enough, and you are fine with 5 lb jumps above 25 lb
Choose PowerBlock Pro 50 if…
- You want 2.5 lb steps all the way to 50 lb and a shorter 13-inch bell
- You prefer a five-year residential warranty and free lower-48 shipping
- You might add PowerBlock kettlebell or barbell attachments, and you will not need more than 50 lb per hand
What do they actually cost right now?
On the pages we fetched on November 10, 2026, the 552 is $399 on sale and $479 regular, with $30 FedEx parcel shipping; Bowflex’s promotion text listed an end time of November 14, 2026, at 11:59 p.m. CT. The Pro 50 is $549 with free residential shipping in the contiguous 48 states. The 552 is cheaper on today’s sale. Over a longer ownership window the Pro 50’s five-year residential warranty (versus two years of Bowflex parts coverage) is the offset, not a lower sticker.
Traditional plates or a compact block?
The 552 is a long, round adjustable bell: 16.9 inches long on Bowflex’s spec sheet, with uniform plates and a non-slip handle. The Pro 50 is PowerBlock’s square, open-handle design at 13" × 7" × 7.25", with color-coded rails and a 38 mm TPR grip. The block is shorter and stores in less length; the tradeoff is a feel that is not the same as a fixed hex or round dumbbell, especially on exercises where the cage can get in the way. BarBend’s small-space praise for PowerBlock is really about this compact profile (it used the expandable Pro 100 EXP as the example).
Who should skip both?
- Anyone who already needs more than 50–52.5 lb per hand. Neither set expands. Look at the Pro 100 EXP (officially up to 100 lb) or a 60 lb QuickDraw.
- Lifters who drop dumbbells. BarBend flags plastic components on the Bowflex design and lower drop tolerance on PowerBlock than all-metal sets.
- People who want a knurled steel handle in the box. The 552 uses a non-slip grip; the Pro 50 ships with TPR, with knurled Pro Series grips sold separately.

This is a format decision, not another adjustable-dumbbell best-of. One QuickDraw pair can replace a rack of fixed bells, but a hex pair is simpler, can be set down more casually, and is sold as final sale.
