NÜOBELL 80 lb Classic Adjustable Dumbbells (Pair, 5–80 lb)
The NÜOBELL 80 is a twist-handle adjustable dumbbell pair spanning 5–80 lb per hand in 16 settings (5 lb steps), in a compact 17-inch body. It's the higher-ceiling alternative to the BowFlex 552's 52.5 lb — buy it if stronger lifts have outgrown a 50 lb cap; the extra range only matters once you're near that ceiling.

What does the research say about the NÜOBELL 80 lb Classic Adjustable Dumbbells?
Every claim below is tied to a source you can open, quoted verbatim — how we research picks.
-
“All RTxs were superior to CTRL for muscle strength and hypertrophy.”
Any structured resistance-training program beats no training for strength and muscle — the program, not the top-end weight, is what works.

“Increases in 1RMSQUAT were ~20 kg on average across groups, but slightly favored LOAD, with a point estimate of 2 kg, or about a 10% greater increase in LOAD compared to REPS.”
Progressing by adding load slightly favors maximal strength — which is why a higher weight ceiling has value once you're strong.

“both low-load and high-load resistance training may produce similar muscle hypertrophy at the whole muscle level when the training is performed to momentary muscular failure”
Honest caveat: heavier weight does not automatically build more muscle — trained to failure, lighter loads grow muscle comparably.

Buy it if
- Stronger intermediate-to-advanced lifters who outgrow a 52.5 lb cap
- Anyone whose rows, presses or goblet squats already push near 50 lb per hand
- Buyers who prefer machined steel plates and a compact, dumbbell-shaped body
- Home lifters wanting one pair to replace a heavy dumbbell rack
Skip it if
- Beginners and light lifters who'll never approach 52.5 lb (the BowFlex 552 costs less)
- Anyone who needs fine 2.5 lb increments for small isolation lifts
- People who drop or throw weights — twist mechanisms dislike abuse
Is the NÜOBELL 80 lb Classic Adjustable Dumbbells worth it?
The adjustable dumbbell to buy when 52.5 lb stops challenging you: 80 lb per hand across 16 settings in a genuinely compact, solid-feeling shell. It costs more than the BowFlex 552 and jumps in flat 5 lb steps, and the honest truth is the extra weight mainly matters for maximal strength — trained hard, lighter loads build muscle just as well. Get it for the headroom, not as a shortcut.

- NÜOBELL 80 vs the BowFlex Results 552 — which should I get?
- The NÜOBELL reaches 80 lb per hand across 16 settings versus the BowFlex's 52.5 lb across 15, so it's the pick if your rows, presses or goblet squats already push toward a 50 lb dumbbell. The trade-offs: the NÜOBELL costs more and uses flat 5 lb jumps, while the 552 offers finer 2.5 lb steps at the low end and a proven dial system. Buy the NÜOBELL for headroom, the BowFlex 552 for a lower price and smaller increments.
- Does lifting more weight actually build more muscle?
- Not by itself. A meta-analysis found low- and high-load training produce similar whole-muscle growth when sets are taken to failure — so the NÜOBELL's 80 lb ceiling doesn't build more muscle than the 552 for most people. Where extra load helps is maximal strength, which studies show slightly favors adding weight over adding reps. The dumbbell just lets you keep progressing; the effort does the work.

- How does the weight range and adjustment work?
- Each dumbbell covers 5 to 80 lb in 16 settings of 5 lb, selected by twisting the handle to lift only the plates you want off the tray. There are no 2.5 lb steps like the BowFlex, so the smallest jump is 5 lb — fine for most lifts but coarse for small isolation work. Source SMRTFT product specs ↗
- Is 80 lb per hand worth the extra money over cheaper adjustables?
- Only if you'll use it. Any structured resistance program beats none, so a 50 lb adjustable is plenty for many people; the NÜOBELL earns its premium once your compound and unilateral lifts genuinely need more than 52.5 lb. Its machined steel plates and compact 17-inch shape are the other draw over dial-and-tray designs. Source Resistance training prescription review (PMC) ↗
