Core Home Fitness Adjustable Dumbbells vs TriForm 3-in-1 Adjustable Weight Set

Buy the Core Home Fitness adjustable dumbbells if you want a straightforward pair of dumbbells with fast twist-of-the-handle changes and a wide weight range. Buy the TriForm if you want one set that also becomes a barbell and a kettlebell. On build, the Core Home Fitness set uses steel plates and knurled steel handles and holds a 4.8 rating from 159 owners; the TriForm holds 4.6 from 114 and its metal plates and multi-mode design draw praise for versatility. The Core Home Fitness pair is the better pure dumbbell; the TriForm is the better one-kit solution.

  • Choose the Core Home Fitness adjustable dumbbells if you mainly lift dumbbells and want quick weight changes, a knurled steel handle and a broad range in one compact pair.
  • Choose the TriForm 3-in-1 system if you want dumbbell, barbell and kettlebell training from a single set of plates without buying three separate pieces.

What reviewers say

Core Home Fitness Adjustable Dumbbells

  • 4.8 / 5159 ratings

Owners rate these highly, with 4.8 out of 5 from 159 ratings. They like the quick twist adjustment, the compact storage and the solid feel of the steel plates. Complaints center on the growing length at heavy settings and the 50 lb ceiling.

What people mention
  • AdjustmentPraisedOwners say the twist handle makes switching weights quick and simple.
  • BuildPraisedReviewers describe the steel plates and cradles as solid and well made.
  • LengthCriticisedThe dumbbell grows longer as weight is added, which some find awkward for certain lifts.
  • Weight rangeMixedThe 5 to 50 lb range suits most home users, but stronger lifters want more.

TriForm 3-in-1 Adjustable Weight Set

  • 4.6 / 5114 ratings

Rated 4.6 out of 5 from 114 ratings, owners like the space saved and the fast weight changes. Most criticism centers on the 45 lb ceiling and the bulk of the adjustable dumbbell.

What people mention
  • VersatilityPraisedOwners like getting dumbbell, barbell and kettlebell work from one set.
  • Weight changesPraisedThe dial lets people change load quickly between sets.
  • FootprintPraisedIt takes far less room than separate fixed weights.
  • Max weightCriticisedThe 45 lb limit is too low for heavy lifts, reviewers say.

Questions and answers

Which is better for a small home gym?
The TriForm, because one set covers dumbbell, barbell and kettlebell work in a single footprint. The Core Home Fitness pair is smaller to store than three separate pieces but only does dumbbell work.
Which has the wider weight range?
The Core Home Fitness set, at 5 to 50 lb per dumbbell in 5 lb steps. The TriForm set runs 20 to 45 lb.
Which is faster to change weight on?
The Core Home Fitness pair, where you twist the handle to the next setting. The TriForm needs you to move and click plates into place, and switching modes takes more handling.
Which feels more solid?
The Core Home Fitness set, with steel plates, a knurled steel handle and a steel cradle. The TriForm's metal plates are solid too, but its convertible frame adds moving parts.
Is the TriForm worth stepping up to over the Core Home Fitness pair?
Only if you will actually use the barbell and kettlebell modes. If you train with dumbbells alone, the Core Home Fitness pair gives you a wider range and a better handle.
Which lasts longer?
Both use metal plates and steel frames. The Core Home Fitness set has a 12-month limited warranty and a simpler mechanism with fewer parts to wear; the TriForm's convertible joints are the parts to watch.
