Home lifters who want to expand the same handles later
A pair of pin-selected block dumbbells running from 5 to 50 pounds per hand, with two 2.5 pound micro weights inside each handle for the half steps. PowerBlock's manual is strict: lift from the centre grip only, keep the pin tethered, and never drop them, because dropping voids the five-year warranty.

- PowerBlock publishes the full owner's manual and a weight range chart
Caveats
- Dropping them from any height voids the warranty, in the maker's own words
