Best Adjustable Dumbbells in Singapore (2026)

Most adjustable dumbbells fail you at the same moment: mid-workout, standing over a half-built handle while your muscles cool down. Almost every set in this guide works that way. The Bowflex SelectTech 552 is the one that doesn't, and it's the one to buy. Turn the dial and two seconds later you're lifting a different weight: finish your presses, click down a few settings, and you're into curls before your rest timer runs out. One pair covers 2.3 to 23.8kg per hand. That's fifteen dumbbells standing in the floor space of one.

The difference that decides this comparison: a dial changes the load in seconds, a plate-select handle has to come apart and go back together at every weight change.

It costs around S$280 as of July 2026. The FEIERDUN and SKOK pairs cost up to S$175 more and still use rebuild-the-handle adjustment, so the extra money buys you a slower mechanism. One thing to check if you shop beyond the 552: its listing is the only one that states the full weight range, so for any other set, confirm the range with the seller before you pay.

The 552 has one hard limit: it stops at 23.8kg per hand. If you already press more than that, skip it and go straight to the 110 lb set, the only one in this guide with enough load for you. And if you're not sure home training will stick yet, start with the ByZoom pair instead. It's the cheapest set here, so you're risking the least while you find out, and you can step up to the 552 once the habit holds.

Every option at a glance

Worth noticing: three of these listings don't fully state their own weight range, and that's the main spec you're paying for. Treat it as a serious mark against them.

Bowflex SelectTech 552: best for most people

The Bowflex SelectTech 552 (S$279.80) spreads its range across 15 dial positions, so the jumps between weights stay small and you're never stuck between a setting that's too light and one that's too heavy. Work the money out against the range and it comes to about S$11.80 per kilo of capacity, the lowest in this guide. The design has been around for years without much change, so its quirks are well known rather than surprises you discover at home.

Two downsides to know about. At light settings the handle stays full length (the unused plates stay on the stand), so light curls feel a bit awkward. It's fine for presses and rows. More importantly, the manual clearly says not to drop them. If you tend to let the last rep crash to the floor, an adjustable set with a dial mechanism isn't for you, at any price. Get fixed rubber dumbbells or train at a gym instead.

The other limit is the ceiling. 23.8kg per hand covers most people's dumbbell work for years, but if your rows are already past that, this set has nothing for you. That's what the next one is for.

110 lb set: for heavier lifters

50kg combined across the pair, the heaviest documented option here. Image from the Amazon listing.

The 110 lb adjustable pair (S$479.74) is 50kg combined, which makes it the heaviest documented set on Amazon right now. It's a generic unbranded set, and weight changes are slower because it's plate-select, but if you need more than 24kg per hand it's the only in-stock option.

For the lifter it fits, the win is real: your rows and presses get room to grow again instead of stalling because the dumbbells ran out before you did. If you're not lifting that heavy yet, though, the extra S$200 over the Bowflex buys headroom you won't touch for a long time. You'd get more out of the Bowflex plus a Gymreapers lifting belt (S$73.50). One practical note for heavy pairs: put proper flooring under them. Our S$2,000 home gym guide covers the flooring cost.

ByZoom pair: the budget option, with a catch

The cheapest set of the group. Image from the Amazon listing.

The ByZoom Fitness pair (S$214.79) is the cheapest option here, S$65 less than the Bowflex. The catch is that the listing doesn't clearly state the weight range or the increments, so there's no way to be sure of the top weight per hand before you order.

If what you're really deciding is whether you'll train at home at all, this is the cheapest way to find out. If the habit sticks, you'll know within a month or two, and you can hand this pair down and upgrade without a second thought. If it doesn't, you've lost S$215 instead of S$480. Just check the listing's range table on the day you order, and if it's still vague, we'd go with the Bowflex.

The three we'd skip

The FEIERDUN pair (S$323.55) and the SKOK pair (S$454.76) both cost more than the Bowflex, and their listings say less about the range and the mechanism. Nothing on either page explains the difference. The 25/55 lb pair set (S$420.86) comes in two versions: the 25 lb one costs S$141 more than the Bowflex for around half the top-end weight, and the 55 lb one is close enough in price to the 110 lb set that you might as well buy that.

Two names you might be looking for: the PowerBlock Elite 90 has been out of stock on Amazon since at least May 2026, and the old Bowflex 1090 listing is gone. We'll update this comparison if either comes back.

Or just join a gym

Worth running the numbers before you buy anything. S$279.80 is roughly three months at a mid-range gym (memberships run about S$90 to S$110 a month), and any gym's rack goes well past 24kg without taking up space at home. If there's a good 24-hour gym near you, that might be the better deal: Anytime Fitness Chai Chee (4.8 stars, 579 Google reviews), Snap Fitness 888 Plaza (5.0, 762 reviews) and Anytime Fitness Jurong Summit (4.9, 411 reviews) are all solid options, and you can browse the rest of the 24-hour gyms here. A common middle ground is a membership plus one Yes4All kettlebell (S$53.26) at home for the days you can't make it. If you'd rather build a proper home setup, start with our S$1,000 home gym guide.
