The Bowflex 552 alternative with a tighter handle and shorter overall length. 5-50 lb in 5 lb increments, slide-dial selection. Cult favorite on r/homegym for tall lifters who hit the wall with PowerBlocks.

- Tall lifters and anyone who finds Bowflex SelectTech dumbbells too long for chest fly and close-grip work. The compact 16-inch length and 50 lb top end suit most home-gym hypertrophy training.
- You need 2.5 lb increments for precise progression on lateral raises or rear delt work, you want sub-5-pound starting weight for rehab, or you need top weight above 50 lb per hand.
Tray footprint roughly 18" wide x 12" deep, plus 36" of clearance in front for picking up and replacing the dumbbells smoothly.
easy — Assemble the cradle base from 4 bolts and a plastic tray. Plan 30 minutes. Place on a flat, stable surface before loading the dumbbells in, since the cradle can tip if the dumbbells are not seated symmetrically. Owners on r/homegym recommend setting the cradle on a horse stall mat to dampen drop noise and protect the floor underneath.
Adjustable dumbbells fill out a home gym once the rack, barbell, plates, and bench are in place. They cover unilateral work that the barbell cannot easily replicate.

What owners actually complain about
Synthesized from owner reviews and community threads. Paraphrased, not quoted.
- 5 lb increments are too coarse for shoulder isolation progression
- Plastic tray feels cheap and can crack if a dumbbell is dropped on it
- Shipping delays are common, sometimes 4 to 8 weeks for backorder
- Slide dial requires firm engagement, occasionally needs lubrication
Buyer sentiment
Based on 151 user mentionsBuyers praise quality, functionality, adjustable weights and ease of use. Mixed feedback on sturdiness and assembly.
Verdict: The shorter adjustable dumbbell that beats Bowflex on fly and close-grip range — for taller lifters who can tolerate 5 lb jumps and a possible backorder wait.
Specs that matter
| Spec | Value |
|---|---|
| Length at 50 lb | 16 in (vs Bowflex ~17.5 in) |
| Increment | 5 lb per dumbbell |
| Mechanism | Slide-dial, plates lock solidly |
| Availability | Often 4–8 wk backorder |
What you get
- Shorter length — smoother chest fly and close-grip press arc
- Solid feel — no rattle through full ROM
- Big space/cost savings vs 10 fixed pairs (~$1,000–1,200)
What you give up
- Coarse 5 lb jumps — too aggressive for lateral raises
- Weak cradle — cracks if dropped; protect with a mat
Buy it if you're tall or do high-volume isolation and want the shorter length. Skip it if you need dumbbells immediately — Bowflex ships fast.
Most owners keep a fixed 12.5/17.5 lb pair (~$50–75) alongside to fill the 5 lb isolation gaps.
