The Original Space-Saving Adjustable Dumbbell Systems
Looking to replace an entire commercial rack of heavy dumbbells without taking up an entire room or relying on fragile, complex gear dials? Invented in 1993, PowerBlock pioneered the world's first selectorized adjustable dumbbell system. Built around a patented nesting weight-block design and heavy-duty magnetic selector pins, PowerBlock delivers fast weight changes with unmatched structural durability.
Whether you are starting with a compact 24 lb set for home mobility work or building out a 100+ lb expandable strength station for heavy presses and rows, PowerBlock offers space-saving equipment engineered to handle decades of intense progressive overload.

The PowerBlock Engineering & Durability Advantage
Replace up to 28 pairs of dumbbells in a single square foot of floor space—built with steel and urethane plates designed to outlast traditional dial-system weights.
-
Patented Selector Pin System: Uses a magnetic, color-coded selector pin that slides into weight rails in seconds—mimicking the simple, bulletproof operation of a commercial gym cable stack.
-
Compact Squared Footprint: Unlike round weights that roll around or traditional dial dumbbells that stay unnecessarily long even at light settings, PowerBlock dumbbells stay short and well-balanced at lower weights.
-
Expandable Stage Upgrades: Many PowerBlock series (like the Pro 100 EXP and Elite USA) allow you to start at 40 or 50 lbs per hand and expand up to 70, 90, or 100 lbs as your strength progresses—saving you from buying a new set later.
-
Urethane & Steel Construction: High-end models feature urethane-coated flex-frame steel plates for quieter lifts, impact resistance, and smooth, corrosion-free durability.
