PowerBlock Pro 50 Adjustable Dumbbells (5–50 lb, Pair)

The PowerBlock Pro 50 is a dial-pin adjustable dumbbell set sold in pairs, ranging from 5–50 lb per hand with 2.5 lb increments. Adjustment uses a secure magnetic polypropylene pin (not a twist dial like SelectTech, but faster than spinlock). The set features durable steel construction with a rubber grip handle and compact dimensions (12.5" L × 7" W × 7.25" H per dumbbell). At 100 lb total weight and engineered to replace up to 16 pairs of fixed dumbbells, it's ideal for small-space lifters and progressive overload training. Includes a 5-year residential warranty and pairs well with a compact home gym. Known for reliability and steady performance, though the pin mechanism feels less premium than twist dials and the footprint is standard for the category.
