Cheapest Dumbbells for Your Home Gym
Cheapest Dumbbells for Your Home Gym — real-world options, costs, and trade-offs
Tommy walks through everything he actually used in his garage gym over six months: adjustable handles (good and bad), used fixed dumbbells, and what he’s eyeing next. If you’re trying to keep costs down and footprint small, here’s the distilled playbook.
Key takeaways
New fixed dumbbells are pricey and eat space. If you want a rack of hex dumbbells, buy used locally.
Adjustable handles can be cheap and compact, but most are annoying to change mid-workout and some get comically long.
Best budget win Tommy tried: inexpensive plastic handles that lock plates solidly (with optional adapters to use your 2" Olympic plates).
If you want a one-and-done adjustable set that feels like real dumbbells and stores small, you’re looking at ~$1,000.
What Tommy tried (pros, cons, and who they’re for)
Gungnir 1" adjustable handles (SlideLock style)
Pros: Ridiculously cool mechanism; quick plate swaps; compact handle.
Cons: Requires 1" standard plates; cheap 1" plates vary in thickness and bore, causing slop, scraping, and a sketchy feel; mismatch with groove spacing.
Verdict: Fun gadget, but the plate variability killed confidence.
Kenuni plastic 1" handles (threaded bolt collars)
Price Tommy paid: about $40–45 shipped (pair).
Pros: Rock-solid clamp; zero rattle; uses 1" plates; optional adapters let you load 2" Olympic plates; feels like a mini pro-style setup.
Cons: You can’t drop them; still slow to change weights; long overall length when lightly loaded can be awkward overhead.
Verdict: Best ultra-budget pick if you can be gentle and don’t mind manual changes.
Strength Co MB12 mini dumbbell (2" Olympic)
Pros: Great for one heavy dumbbell (goblet squats, rows) while leaving another pair set up; stout with real collars; looks clean.
Cons: Not a full replacement for a set; with two handles you now need four collars; still stops/starts to swap plates.
Verdict: Nice complement piece, not a holistic solution.
Used hex dumbbells (10–50 lb sets)
Pros: Always on Marketplace; often $300–$500 with a rack; no fiddling mid-workout; classic feel.
Cons: Big footprint; patience required to find a decent lot; don’t buy new unless you have to.
Verdict: If you’ve got space and can wait for a deal, this beats living in plate-swap purgatory.
Higher-end adjustable sets Tommy’s considering
REP Pepin: Starts around $900, add a stand and you’re near $1,000. Solves the length, speed, and feel issues better than budget handles.
Other options: PowerBlocks and Bowflex adjustables are proven; REP QuickDraw goes to ~60 lb at a lower price, but limited top-end weight and still not a full “dumbbell feel” for some lifters.
Buyer cheat sheet
Under $100 (tight budget, tiny space)
Kenuni-style plastic 1" handles + cheap 1" plates. Add 2" adapters if you already own Olympic plates.
Best for curls, lateral raises, light accessories. Don’t drop them.
$300–$600 (value hunter, some space)
Stalk Marketplace for a used 10–50 lb hex set with a rack. Expect $300–$500 depending on your area.
Great for supersets and quick changes without reloading.
~$1,000 (premium adjustable, minimal footprint)
REP Pepin or similar high-end adjustable system. Faster changes, better ergonomics, and less “sword-length” handles.
Good if you want to “solve dumbbells forever” without dedicating a wall.
Practical tips Tommy learned
Avoid buying new cheap hex dumbbells; used deals are everywhere.
If you must go 1" standard, expect plate variance. That’s what caused the Gungnir headache.
Adjustable handles multiply the number of collars you own. Plan on four if you buy two handles.
Long handles feel the worst on overhead moves. Favor compact designs if presses are a priority.

Who should do what
