Yes4All Spinlock Dumbbell Set Review (2027): The Load a $500 Build Is Built On
Research review of the Yes4All 105 lb spinlock set as a budget core: cost per pound logic, change-time programming, collar discipline, and the decade ownership case.
Yes4All Adjustable Dumbbell Set with Spinlock Collars (105 lb Pair)
105 lb of cast iron across a pair: the most real load a $500 build can own.
- 105 lb total across the pair set (52.5 lb per hand); larger total sets also sold
- Weight range
- Set by loaded plates; smallest included plate decides the step
- Increments
- Spinlock star collars on threaded handles
- Mechanism
Our verdict
Every budget build makes one decision that decides it, and this set is that decision made well. 105 lb of standard cast iron across a pair delivers more progressable load per dollar than any mechanism at any price, accepts cheap plate additions forever, and has no failure mode more dramatic than a collar to retighten. Its cost is paid in the workout, not the wallet: changes take a minute, handles are utilitarian, and circuits need restructuring into straight sets. For a first gym under $500, that exchange is not a compromise to apologize for; it is the entire strategy working as designed.
What we like
- Cast iron plates are a decade purchase, droppable on a mat and immune to mechanism failure
- Standard pattern plates mean cheap extra plates anywhere when strength outgrows the set
- Load ceiling per hand covers years of beginner and intermediate progression
What to watch out for
- Change time is the slowest in home gym equipment; program in straight sets
- Star collars loosen with vibration and need a hand check between sets as a standing habit
Who it is for
First-time builders and returning lifters who want maximum load and longevity from the largest slice of a $500 total, and who train in straight sets.
The cost per pound argument, in full
Adjustable mechanisms charge for convenience: dials, pins, and trays are engineering a spinlock set does not contain. What remains is iron and thread, the two cheapest durable things in fitness. The result is a ceiling of 52.5 lb per hand at a share of the budget that leaves room for a bench, a bar, bands, and a mat. Any competing core either costs the build its second piece or caps the load years earlier. That is the whole review in one paragraph; the rest is living with it.
Programming around a one-minute change
Straight sets, supersets of same-weight pairs, and top-set structures all fit spinlock life naturally. What fails is the follow-along circuit with four loads in four minutes. Owners adapt by staging plates beside the handles, pre-setting the second dumbbell during rest periods, and choosing programs written for barbell logic, where load changes were always events. Two weeks in, the routine is invisible; the savings are not.
Collar discipline and thread care
Star collars walk loose under vibration, and the ownership habit is a squeeze check before every set, as automatic as a seatbelt. Threads stay clean and dry; a gritty thread gets brushed, never forced. Collars are cheap wear items with replacements everywhere, which is the deeper point: every part of this system that can wear is a part you can replace for pocket change, forever.
The decade view
Owner reports run long on this class of product because there is little to report: the iron persists. Sets get inherited, resold at real value, and expanded with plates bought one pair at a time. In a build designed to upgrade around its core, a core that never needs upgrading is the correct foundation, and it is why this set leads the hub despite being its least glamorous object.

FAQ
Questions, answered straight
Is 105 lb total enough for a first year?
For the overwhelming majority of first-year lifters, yes: 52.5 lb per hand covers presses, rows, split squats, and goblet work through the beginner phase and well into intermediate training. The honest exceptions are strong returners and former athletes, who should price the larger total sets in the same line.
Can I buy more plates later, and will they fit?
Yes. The set uses the standard 1 in plate pattern, the most common in existence, so additional plates from any maker fit its handles. That openness is a core reason it anchors a budget build: growth costs plates, not a new system.
Do the handles hurt on presses?
The threaded ends extend past the plates and can contact thighs at the end of some movements. Owners solve it with setup: plates loaded to keep ends shorter on pressing days, or a towel at the contact point. It is an annoyance with known fixes, priced into every spinlock review including this one.
