What does the research say about the BowFlex Results Series 552 SelectTech Dumbbells?
Every claim below is tied to a source you can open, quoted verbatim — how we research picks.
-
“Muscle-strengthening activities were associated with a 10–17% lower risk of all-cause mortality, cardiovascular disease (CVD), total cancer, diabetes and lung cancer.”
Strength training is associated with lower all-cause mortality.
British Journal of Sports Medicine (Momma et al.) · 2022 ↗ -
“Resistance training is effective for increasing lean tissue mass and muscular strength in older adults”
Resistance training builds lean mass and strength — but the training does the work, not the equipment.
Open Access Journal of Sports Medicine (meta-analysis) · 2017 ↗ -
“Load progressions were slightly more effective for maximal strength and equally effective for muscular endurance performance.”
Progressive overload via increasing load is slightly better for maximal strength — which is why an adjustable load matters.

Buy it if
- Apartment/small-space lifters who can't store a rack
- Beginner-to-intermediate strength trainees
- People wanting fast weight changes between exercises
- Buyers who want the safer post-recall redesign
Skip it if

- Budget buyers fine with cheaper fixed or spinlock dumbbells
Is the BowFlex Results Series 552 SelectTech Dumbbells worth it?
The best space-to-strength trade in a home gym, and now the version to buy after the original's recall. Buy it for the 5–52.5 lb range in one footprint — just know dial dumbbells are more delicate than steel, 52.5 lb is a real ceiling, and progress comes from the program, not the gear.

- Is this the recalled version?
- No. The original SelectTech 552/1090 were recalled in June 2025 for plates that could dislodge. The Results Series 552 is the redesign with metal locking tabs and is the version sold now. Source BowFlex recall info ↗
- How much weight does each dumbbell go up to?
- 5 to 52.5 lb per hand across 15 settings — 2.5 lb jumps to 25 lb, then 5 lb jumps. Stronger lifters on big lifts (rows, presses) may outgrow the top end. Source BowFlex product page ↗
- Is it actually worth it over fixed dumbbells?
- For space: yes — one pair replaces 15 sets. But dials add fragility and a bulkier shape than solid dumbbells, and you still have to do the training; the gear doesn't train you. Source Load progression study (PMC) ↗
- BowFlex Results 552 vs NÜOBELL: which adjustable dumbbell?
- The NÜOBELL 580 reaches 80 lb across 16 settings versus the BowFlex's 52.5 lb across 15, so stronger lifters get more headroom. Both are compact adjustables; the BowFlex uses dual selection dials, the NÜOBELL a twist handle. Warranty is 2 yr parts on the BowFlex versus 2 yr (4 yr direct) on the NÜOBELL. Choose the NÜOBELL for a higher ceiling, the BowFlex for the proven dial system and post-recall redesign.
- Does training with adjustable dumbbells actually build strength?
- The training builds the strength, not the tool. Muscle-strengthening activity is linked to 10-17% lower all-cause mortality, and resistance training reliably increases lean tissue mass and muscular strength — but those gains come from progressive overload, which the 5-52.5 lb range simply lets you keep adding. The dumbbells enable the program; they don't do the work. Source British Journal of Sports Medicine (PMC) ↗Open Access J Sports Med (PMC) ↗
