PowerBlock
PowerBlock pioneered the pin-select adjustable dumbbell category and remains the benchmark brand in compact home-gym dumbbells. The premise is simple: replace an entire dumbbell rack with a pair of stackable blocks that adjust from light warm-up loads to heavy training weights using a selector pin and add-on adder weights, all in a footprint that fits next to a desk or in a garage corner.
The lineup is organized by both capacity and expandability. The Elite EXP series anchors the expandable line -- starting at 5 to 50 lb per hand and expanding with capacity kits to 70 lb and then to 90 lb -- with 2.5 lb adder weights for micro-adjustments that let lifters dial in precise loads for delts, triceps, and biceps. The Pro and Sport non-expandable lines (Sport 24, Pro 32, Sport 50, PowerBlock 50) cover users who want a fixed capacity at a lower entry price. Newer flagship models extend the range up to 100 lb per hand for serious strength work without the storage hit of a traditional rack.
PowerBlock's stand ecosystem is designed to match the dumbbell ergonomics. The PowerStand 2.0 fits compact non-expandable sets up to 50 lb. The Large Column Stand (Made in USA) holds expandable sets up to 90 lb and includes circular holders for the 2.5 lb adder weights so they stay organized between sets. The PowerMax 2.0 Stand scales to 100 lb per tray for the largest Pro and Elite configurations. Split-tray ergonomics across the stand line let users step in and grab a block without bending. The Pro Series Kettlebell Handle converts an existing Pro dumbbell stack into a pin-adjusted kettlebell for swings, goblet squats, cleans, and carries -- expanding training without adding storage.
Per the vendor: warranties are 1-year limited for residential use across the stand line, and stands ship in one carton with simple assembly hardware included.
