Quick & Easy Adjustment
One twist, one second. The selector dial changes resistance mid-workout, keeping supersets and drop sets moving without a break in tempo.

- HBHadrien B.Verified BuyerReviewingAmStaff Adjustable Dumbbell 3-40LBI recommend this productRated 5 out of 5 stars5 months agosuper conviennent even for strong lifters
Bought a set, they are very easy to use, the rubber grip is good, they are not too bulky, and all of this is considering the low price this pair sells for.
40lbs can get low for certain exercises for strong lifters, but in that case it is still very very convenient for the warmups, otherwise it's plenty heavy for a multitude of other exercises.
They are still new but they work well.
