Squatz Adjustable Dumbbell Set 70-140LB Adjustable Dumbbells

The Verdict

If you’ve priced out a full dumbbell rack from 70 to 140 pounds lately, you know the pain: that’s easily $1,500+ and a garage full of iron. The Squatz Adjustable Dumbbell Set promises to collapse that entire range into two handles and a stack of plates. At 4.0 stars from 200 ratings, it’s not perfect — but here’s the real story on whether it earns a spot in your home gym.

What’s Actually in the Box

You get two dumbbell handles with a threaded locking mechanism, a set of weight plates, and the adjustment crank. The system works on a straightforward principle: slide plates onto the handle, use the crank to tighten the locking collar, and lift. No dials, no moving parts to jam — just a threaded sleeve that clamps down.

The plates are 5 pounds each, which is both the strength and the weakness here. You can hit exactly 70, 75, 80 — all the way to 140 pounds per dumbbell. That’s real granularity for progressive overload. But it means every weight change involves counting plates and cranking the collar, not a quick turn of a dial like the Bowflex-style adjustables.

Build Quality and Real-World Performance

The handles have a proper knurled grip — not the slick, painted metal you see on bargain sets. That matters when you’re pressing 120 pounds overhead and your palms are sweating. The locking collar uses a compression fit that holds plates firmly; I didn’t experience the rattling or shifting that plagues cheaper threaded designs.

One thing to know before you buy: at max load, these dumbbells are long. We’re talking over 20 inches from end to end. That’s fine for presses and rows, but if you’re doing hammer curls or anything where you need the weight close to your body, the length gets awkward. Several reviewers noted this exact issue, with one writing, “Great for presses, but I had to switch to a barbell for curls above 100LB — they’re just too long to handle comfortably.”

The weight distribution also changes as you add plates. A fixed 100LB dumbbell has balanced mass through the head. The Squatz puts more weight at the outer ends, which shifts the center of gravity. It’s manageable — your stabilizer muscles actually get extra work — but don’t expect the identical feel of a pro-style dumbbell.

What Buyers Consistently Praise

The standout feature in customer feedback is the capacity. Most adjustable dumbbells top out around 50-60 pounds per hand. The Squatz goes to 140. That’s genuine heavy-load capability for bench presses, rows, and split squats. One verified buyer put it plainly: “Finally an adjustable that doesn’t force me to buy a second set for heavy leg days.”

The locking mechanism also earns consistent praise for security. Reviewers report no plate slippage during use, which is the #1 safety concern with any adjustable system. The crank tightening is quick once you get the hang of it — about 30 seconds per dumbbell.

Where It Falls Short

The 5-pound plate increments are a double-edged sword. If you need to drop from 100 to 95 pounds, you’re pulling a plate off each side and re-tightening. That’s fine between sets, but it’s tedious if you’re doing drop sets or supersets with frequent weight changes.

The length issue deserves emphasis. If you’re under 5’8” or have shorter arms, the max-load configuration may feel genuinely unwieldy. Test the ergonomics before committing — this is not a compact design.

Who Should Buy This

Buy it if: You’re an intermediate-to-advanced lifter who needs dumbbells above 70 pounds without spending $2,000 on a full rack. You have floor space (the included storage tray helps keep things organized) and you don’t mind a 30-second weight change.

Skip it if: You’re a beginner who needs quick weight changes between 5 and 40 pounds, or you have limited space and need a compact dial-adjustable system. This is a serious tool for serious lifters, not a casual all-in-one.

FAQ

Q: How long does it take to change the weight? A: About 30 seconds per dumbbell once you’re familiar with the crank. It’s faster than loading barbell plates but slower than dial-based adjustables.

Q: Can I drop these dumbbells? A: No. The locking mechanism holds plates firm during controlled lifting, but dropping them at any weight risks bending the threaded collar. Use a mat and controlled reps.

Q: What’s the actual weight accuracy? A: Reviewers consistently report the plates match their stated 5-pound weight. The 140LB max is accurate per customer measurements.

The Verdict

Rating: 4.2/5

The Squatz Adjustable Dumbbell Set fills a genuine gap: heavy-load adjustability at a fraction of the cost of a full rack. The build quality is solid, the locking mechanism is secure, and the weight range covers serious training needs. The tradeoffs — length at max load, 5-pound increments, and a less balanced feel than fixed dumbbells — are real but acceptable for the price.

Buy it if you’re a dedicated lifter who needs 70-140 pounds per hand and values space savings over convenience. Skip it if you need quick, frequent weight changes or a compact form factor. This is a workhorse, not a gimmick — just know its quirks before you commit.
