The Trulap 8592 G4 puts 52 dumbbells in one pair. Twist the handle in the docking base to pick any weight from 8.5 to 92 lb. Steel plates and a knurled aluminum handle give it the feel of a classic gym dumbbell.


Set the dumbbells in the docking bases and turn the knurled grip. Feel the click and lift.
One set covers warm-ups, presses, rows and heavy compound lifts.
Steps of 2.5 to 3.5 lb help you progress without big jumps.
Pounds show on one side and kilograms on the other.

Iron cast plates with an electroplated stainless finish.
A 34 mm grip with secure knurling for a confident hold.
The dumbbell gets shorter at lighter weights for a compact feel.
Unused plates stay locked in the base while you lift.
Trulap moves in 2.5 to 3.5 lb steps. Many twist-dial sets jump 5 or 10 lb at a time. Smaller steps help you add weight without breaking form.
Flat steel heads and an aluminum knurled handle. No plastic shell and no knob sticking out of the end.
Only the plates you pick leave the base. Light sets stay compact and easy to swing through curls and raises.
92 lb per hand covers heavy presses, rows and lunges.
Choose the 8592 G4 if you lift heavy or want one set that will last as you get stronger. Each docking base needs about 14.6 in x 8.5 in of floor space. Add a G2 or G3 rack to bring the dumbbells to waist height.
