How Adjustable Dumbbells Work

Most adjustable systems use one of three mechanisms. Each trades off speed, durability, and fine weight increments (micro‑loads). Choose based on your priorities and training style.

Dial Systems

Turn a dial to latch plates in one motion. Fastest for drop‑sets and circuits.

  • • Very quick changes
  • • Limited micro‑load options
  • • More moving parts to maintain

Pin/Selector Systems

Insert a selector pin to choose the plate stack. Great balance of speed and durability.

  • • Quick changes
  • • Often supports micro‑plates
  • • Robust under frequent use

Plate/Spin‑Lock

Add standard plates and secure with a collar. Slowest, but highly customizable and inexpensive.

  • • Cheapest and modular
  • • Micro‑load friendly
  • • Slowest weight changes
